: any target value must be unique (i.e., occur only once)
Properties (9)
description Uniquely identifies this assessment activity. This UUID may be referenced elsewhere in an OSCAL document when referring to this information. A UUID should be consistently used for a given included activity across revisions of the document.
description The title for this included activity.
description A human-readable description of this included activity.
use name prop
group as props
Remarks
Properties permit the deployment and management of arbitrary controlled values, within OSCAL objects. A property can be included for any purpose useful to an application or implementation. Typically, properties will be used to sort, filter, select, order, and arrange OSCAL content objects, to relate OSCAL objects to one another, or to associate an OSCAL object to class hierarchies, taxonomies, or external authorities. Thus, the lexical composition of properties may be constrained by external processes to ensure consistency.
Property allows for associated remarks that describe why the specific property value was applied to the containing object, or the significance of the value in the context of the containing object.
group as links
Remarks
To provide a cryptographic hash for a remote target resource, a local reference to
a back matter resource
is needed. The resource allows one or more hash values to be provided using the rlink/hash
object.

Remarks
In the context of an assessment plan, this construct is used to identify the controls and control objectives that are to be assessed. In the context of an assessment result, this construct is used to identify the actual controls and objectives that were assessed, reflecting any changes from the plan.
When resolving the selection of controls and control objectives, the following processing will occur:
1. Controls will be resolved by creating a set of controls based on the control-selections by first handling the includes, and then removing any excluded controls.
2. The set of control objectives will be resolved from the set of controls that was generated in the previous step. The set of control objectives is based on the control-objective-selection by first handling the includes, and then removing any excluded control objectives.
This can be optionally used to define the set of controls and control objectives that are assessed by this step.
group as responsible-roles
Remarks
Identifies the roles, and optionally the parties, associated with this step that is part of an assessment activity.
use name related-controls
Remarks
In the context of an assessment plan, this construct is used to identify the controls and control objectives that are to be assessed. In the context of an assessment result, this construct is used to identify the actual controls and objectives that were assessed, reflecting any changes from the plan.

This can be optionally used to define the set of controls and control objectives that are assessed or remediated by this activity.
group as responsible-roles
Remarks
Since responsible-role
associates multiple party-uuid
entries with a single role-id
, each role-id must be referenced only once.
description Specifies contents to be added into controls, in resolution
Remarks
When no id-ref
is given, the addition is inserted into the control targeted by the alteration at
the start or end as indicated by position
. Only position
values of "starting" or "ending" are permitted when there is no id-ref
.
id-ref
, when given, should indicate, by its ID, an element inside the control to serve as
the anchor point for the addition. In this case, position
value may be any of the permitted values.
Constraint (1)
allowed values for prop/@name
The value may be locally defined, or one of the following:
- label: A human-readable label for the parent context.
- sort-id: An alternative identifier, whose value is easily sortable among other such values in the document.
Properties (7)
description Where to add the new content with respect to the targeted element (beside it or inside it)
Constraint (1)
allowed values
The value must be one of the following:
- before: Preceding the id-ref target
- after: Following the id-ref target
- starting: Inside the control or id-ref target, at the start
- ending: Inside the control or id-ref target, at the end
description Target location of the addition.
description A name given to the control, which may be used by a tool for display and navigation.
use name param
group as params
Remarks
In a catalog, a parameter is typically used as a placeholder for the future assignment
of a parameter value, although the OSCAL model allows for the direct assignment of
a value if desired by the control author. The value
may be optionally used to specify one or more values. If no value is provided, then
it is expected that the value will be provided at the Profile or Implementation layer.
A parameter can include a variety of metadata options that support the future solicitation
of one or more values. A label
provides a textual placeholder that can be used in a tool to solicit parameter value
input, or to display in catalog documentation. The desc
provides a short description of what the parameter is used for, which can be used
in tooling to help a user understand how to use the parameter. A constraint
can be used to provide criteria for the allowed values. A guideline
provides a recommendation for the use of a parameter.
use name prop
group as props
Remarks
Properties permit the deployment and management of arbitrary controlled values, within OSCAL objects. A property can be included for any purpose useful to an application or implementation. Typically, properties will be used to sort, filter, select, order, and arrange OSCAL content objects, to relate OSCAL objects to one another, or to associate an OSCAL object to class hierarchies, taxonomies, or external authorities. Thus, the lexical composition of properties may be constrained by external processes to ensure consistency.
Property allows for associated remarks that describe why the specific property value was applied to the containing object, or the significance of the value in the context of the containing object.
group as links
Remarks
To provide a cryptographic hash for a remote target resource, a local reference to
a back matter resource
is needed. The resource allows one or more hash values to be provided using the rlink/hash
object.
The OSCAL link
is a roughly based on the HTML link element.
group as parts
Remarks
A part
provides for logical partitioning of prose, and can be thought of as a grouping structure
(e.g., section). A part
can have child parts allowing for arbitrary nesting of prose content (e.g., statement
hierarchy). A part
can contain prop
objects that allow for enriching prose text with structured name/value information.
A part
can be assigned an optional id
, which allows for internal and external references to the textual concept contained
within a part
. A id
provides a means for an OSCAL profile, or a higher layer OSCAL model to reference
a specific part within a catalog
. For example, an id
can be used to reference or to make modifications to a control statement in a profile.
Use of part
and prop
provides for a wide degree of extensibility within the OSCAL catalog model. The optional
ns
provides a means to qualify a part's name
, allowing for organization-specific vocabularies to be defined with clear semantics.
Any organization that extends OSCAL in this way should consistently assign a ns
value that represents the organization, making a given namespace qualified name
unique to that organization. This allows the combination of ns
and name
to always be unique and unambiguous, even when mixed with extensions from other organizations.
Each organization is responsible for governance of their own extensions, and is strongly
encouraged to publish their extensions as standards to their user community. If no
ns
is provided, the name is expected to be in the "OSCAL" namespace.
To ensure a ns
is unique to an organization and naming conflicts are avoided, a URI containing a
DNS or other globally defined organization name should be used. For example, if FedRAMP
and DoD both extend OSCAL, FedRAMP will use the ns
"https://fedramp.gov", while DoD will use the ns
"https://defense.gov" for any organization specific name
.
Tools that process OSCAL content are not required to interpret unrecognized OSCAL extensions; however, OSCAL compliant tools should not modify or remove unrecognized extensions, unless there is a compelling reason to do so, such as data sensitivity.

Constraint (1)
matches: a target (value) must match the regular expression '[A-Z](2)'.
description If the selected security level is different from the base security level, this contains the justification for the change.
description An Alter element specifies changes to be made to an included control when a profile is resolved.
Remarks
Use @control-id
to indicate the scope of alteration.
It is an error for two alter
elements to apply to the same control. In practice, multiple alterations can be applied
(together), but it creates confusion.
At present, no provision is made for altering many controls at once (for example, to systematically remove properties or add global properties); extending this element to match multiple control IDs could provide for this.
Properties (3)
group as removes
Remarks
Use name-ref
, class-ref
, id-ref
or generic-identifier
to indicate class tokens or ID reference, or the formal name, of the component to
be removed or erased from a control, when a catalog is resolved. The control affected
is indicated by the pointer on the removal's parent (containing) alter
element.
To change an element, use remove
to remove the element, then add
to add it back again with changes.
group as adds
Remarks
When no id-ref
is given, the addition is inserted into the control targeted by the alteration at
the start or end as indicated by position
. Only position
values of "starting" or "ending" are permitted when there is no id-ref
.
id-ref
, when given, should indicate, by its ID, an element inside the control to serve as
the anchor point for the addition. In this case, position
value may be any of the permitted values.
description An As-is element indicates that the controls should be structured in resolution as they are structured in their source catalogs. It does not contain any elements or attributes.
description Identifies the assets used to perform this assessment, such as the assessment team, scanning tools, and assumptions.

Property (1)
description A resource associated with content in the containing document. A resource may be directly included in the document base64 encoded or may point to one or more equivalent internet resources.
group as resources
Remarks
A resource can be used in two ways. 1) it may point to an specific retrievable network
resource using a rlink
, or 2) it may be included as an attachment using a base64
. A resource may contain multiple rlink
and base64
entries that represent alternative download locations (rlink) and attachments (base64)
for the same resource. Both rlink and base64 allow for a media-type
to be specified, which is used to distinguish between different representations of
the same resource (e.g., Microsoft Word, PDF). When multiple rlink
and base64
items are included for a given resource, all items must contain equivalent information.
This allows the document consumer to choose a preferred item to process based on a
the selected item's media-type
. This is extremely important when the items represent OSCAL content that is represented
in alternate formats (i.e., XML, JSON, YAML), allowing the same OSCAL data to be processed
from any of the available formats indicated by the items.
When a resource includes a citation, then the title
and citation
properties must both be included.
Constraints (7)

Properties (9)
description A globally unique identifier that can be used to reference this defined resource elsewhere in an OSCAL document. A UUID should be consistently used for a given resource across revisions of the document.
description A name given to the resource, which may be used by a tool for display and navigation.
description A short summary of the resource used to indicate the purpose of the resource.
group as props
use name prop
Remarks
Properties permit the deployment and management of arbitrary controlled values, within OSCAL objects. A property can be included for any purpose useful to an application or implementation. Typically, properties will be used to sort, filter, select, order, and arrange OSCAL content objects, to relate OSCAL objects to one another, or to associate an OSCAL object to class hierarchies, taxonomies, or external authorities. Thus, the lexical composition of properties may be constrained by external processes to ensure consistency.
Property allows for associated remarks that describe why the specific property value was applied to the containing object, or the significance of the value in the context of the containing object.
group as document-ids
value key identifier
Remarks
This element is optional, but it will always have a valid value, as if it is missing the value of "document-id" is assumed to be equal to the UUID of the root. This requirement allows for document creators to retroactively link an update to the original version, by providing a document-id on the new document that is equal to the uuid of the original document.
description A citation consisting of end note text and optional structured bibliographic data.
Remarks
The text
is used to define the endnote text, without any required bibliographic structure.
If structured bibliographic data is needed, then the biblio
can be used for this purpose.
A biblio
can be used to capture a structured bibliographical citation in an appropriate format.

Remarks
This construct is different from link
, which makes no provision for a hash or formal title.
Multiple rlink
can be included for a resource. In such a case, all provided rlink
items are intended to be equivalent in content, but may differ in structure. A media-type
is used to identify the format of a given rlink, and can be used to differentiate
a items in a collection of rlinks. The media-type
also provides a hint to the OSCAL document consumer about the structure of the resource
referenced by the rlink
.

Remarks
In a catalog, a parameter is typically used as a placeholder for the future assignment
of a parameter value, although the OSCAL model allows for the direct assignment of
a value if desired by the control author. The value
may be optionally used to specify one or more values. If no value is provided, then
it is expected that the value will be provided at the Profile or Implementation layer.
A parameter can include a variety of metadata options that support the future solicitation
of one or more values. A label
provides a textual placeholder that can be used in a tool to solicit parameter value
input, or to display in catalog documentation. The desc
provides a short description of what the parameter is used for, which can be used
in tooling to help a user understand how to use the parameter. A constraint
can be used to provide criteria for the allowed values. A guideline
provides a recommendation for the use of a parameter.
group as controls
Remarks
Controls may be grouped using group
, and controls may be partitioned using part
or further enhanced (extended) using control
.
A control must have a part with the name "statement", which represents the textual narrative of the control. This "statement" part must occur only once, but may have nested parts to allow for multiple paragraphs or sections of text.
group as groups
Remarks
Catalogs can use a group
to collect related controls into a single grouping. That can be useful to group controls
into a family or other logical grouping.
A group
may have its own properties, statements, parameters, and references, which are inherited
by all members of that group.
Remarks
Provides a collection of identified resource
objects that can be referenced by a link

Remarks
Properties permit the deployment and management of arbitrary controlled values, within OSCAL objects. A property can be included for any purpose useful to an application or implementation. Typically, properties will be used to sort, filter, select, order, and arrange OSCAL content objects, to relate OSCAL objects to one another, or to associate an OSCAL object to class hierarchies, taxonomies, or external authorities. Thus, the lexical composition of properties may be constrained by external processes to ensure consistency.
Property allows for associated remarks that describe why the specific property value was applied to the containing object, or the significance of the value in the context of the containing object.
group as links
Remarks
To provide a cryptographic hash for a remote target resource, a local reference to
a back matter resource
is needed. The resource allows one or more hash values to be provided using the rlink/hash
object.
The OSCAL link
is a roughly based on the HTML link element.
description A Combine element defines whether and how to combine multiple (competing) versions of the same control
Remarks
Whenever combining controls from multiple (import) pathways, an issue arises of what to do with clashing invocations (multiple competing versions of a control).
This setting permits a profile designer to apply a rule for the resolution of such cases. In a well-designed profile, such collisions would ordinarily be avoided, but this setting can be useful for defining what to do when it occurs.
Property (1)
description A collection of component descriptions, which may optionally be grouped by capability.
root name component-definition
Constraints (2)
index for component
an index index-system-component-uuid
shall list values returned by targets component
using keys constructed of key field(s) @uuid

group as components
Remarks
Components may be products, services, APIs, policies, processes, plans, guidance, standards, or other tangible items that enable security and/or privacy.
The type
indicates which of these component types is represented.
A group of components may be aggregated into a capability
. For example, an account management capability that consists of an account management
process, and a Lightweight Directory Access Protocol (LDAP) software implementation.
Capabilities are expressed by combining one or more components.
group as capabilities
Remarks
Provides a collection of identified resource
objects that can be referenced by a link
with a rel
value of "reference" and an href
value that is a fragment "#" followed by a reference to a reference identifier. Other
specialized link "rel" values also use this pattern when indicated in that context
of use.
description A structured information object representing a security or privacy control. Each security or privacy control within the Catalog is defined by a distinct control instance.
Remarks
Controls may be grouped using group
, and controls may be partitioned using part
or further enhanced (extended) using control
.
A control must have a part with the name "statement", which represents the textual narrative of the control. This "statement" part must occur only once, but may have nested parts to allow for multiple paragraphs or sections of text.
Constraints (4)

the cardinality of part[@name='statement']
is constrained: 1; maximum 1.
allowed values for prop/@name
The value may be locally defined, or one of the following:
- label: A human-readable label for the parent context.
- sort-id: An alternative identifier, whose value is easily sortable among other such values in the document.
- status: The status of a control. For example, a value of 'withdrawn' can indicate that the control has been withdrawn and should no longer be used.
allowed value for prop[@name='status']/@value
The value must be one of the following:
- withdrawn: The control is no longer used.
allowed values for link/@rel
The value may be locally defined, or one of the following:
- reference: The link cites an external resource related to this control.
- related: The link identifies another control with bearing to this control.
- required: The link identifies another control that must be present if this control is present.
- incorporated-into: The link identifies other control content where this control content is now addressed.
Properties (8)
description A unique identifier for a specific control instance that can be used to reference the control in other OSCAL documents. This identifier's uniqueness is document scoped and is intended to be consistent for the same control across minor revisions of the document.
description A textual label that provides a sub-type or characterization of the control.
Remarks
A class
can be used in validation rules to express extra constraints over named items of
a specific class
value.
A class
can also be used in an OSCAL profile as a means to target an alteration to control
content.
description A name given to the control, which may be used by a tool for display and navigation.
group as params
use name param
Remarks
In a catalog, a parameter is typically used as a placeholder for the future assignment
of a parameter value, although the OSCAL model allows for the direct assignment of
a value if desired by the control author. The value
may be optionally used to specify one or more values. If no value is provided, then
it is expected that the value will be provided at the Profile or Implementation layer.
A parameter can include a variety of metadata options that support the future solicitation
of one or more values. A label
provides a textual placeholder that can be used in a tool to solicit parameter value
input, or to display in catalog documentation. The desc
provides a short description of what the parameter is used for, which can be used
in tooling to help a user understand how to use the parameter. A constraint
can be used to provide criteria for the allowed values. A guideline
provides a recommendation for the use of a parameter.
group as props
use name prop
Remarks
Properties permit the deployment and management of arbitrary controlled values, within OSCAL objects. A property can be included for any purpose useful to an application or implementation. Typically, properties will be used to sort, filter, select, order, and arrange OSCAL content objects, to relate OSCAL objects to one another, or to associate an OSCAL object to class hierarchies, taxonomies, or external authorities. Thus, the lexical composition of properties may be constrained by external processes to ensure consistency.
Property allows for associated remarks that describe why the specific property value was applied to the containing object, or the significance of the value in the context of the containing object.
group as links
Remarks
To provide a cryptographic hash for a remote target resource, a local reference to
a back matter resource
is needed. The resource allows one or more hash values to be provided using the rlink/hash
object.
The OSCAL link
is a roughly based on the HTML link element.
group as parts
Remarks
A part
provides for logical partitioning of prose, and can be thought of as a grouping structure
(e.g., section). A part
can have child parts allowing for arbitrary nesting of prose content (e.g., statement
hierarchy). A part
can contain prop
objects that allow for enriching prose text with structured name/value information.
A part
can be assigned an optional id
, which allows for internal and external references to the textual concept contained
within a part
. A id
provides a means for an OSCAL profile, or a higher layer OSCAL model to reference
a specific part within a catalog
. For example, an id
can be used to reference or to make modifications to a control statement in a profile.
Use of part
and prop
provides for a wide degree of extensibility within the OSCAL catalog model. The optional
ns
provides a means to qualify a part's name
, allowing for organization-specific vocabularies to be defined with clear semantics.
Any organization that extends OSCAL in this way should consistently assign a ns
value that represents the organization, making a given namespace qualified name
unique to that organization. This allows the combination of ns
and name
to always be unique and unambiguous, even when mixed with extensions from other organizations.
Each organization is responsible for governance of their own extensions, and is strongly
encouraged to publish their extensions as standards to their user community. If no
ns
is provided, the name is expected to be in the "OSCAL" namespace.
To ensure a ns
is unique to an organization and naming conflicts are avoided, a URI containing a
DNS or other globally defined organization name should be used. For example, if FedRAMP
and DoD both extend OSCAL, FedRAMP will use the ns
"https://fedramp.gov", while DoD will use the ns
"https://defense.gov" for any organization specific name
.
Tools that process OSCAL content are not required to interpret unrecognized OSCAL extensions; however, OSCAL compliant tools should not modify or remove unrecognized extensions, unless there is a compelling reason to do so, such as data sensitivity.
group as controls
Remarks
Controls may be grouped using group
, and controls may be partitioned using part
or further enhanced (extended) using control
.
A control must have a part with the name "statement", which represents the textual narrative of the control. This "statement" part must occur only once, but may have nested parts to allow for multiple paragraphs or sections of text.
description A reference to a control with a corresponding id
value.
description Defines how the component or capability supports a set of controls.
Remarks
Use of set-parameter
in this context, sets the parameter for all related controls referenced in an implemented-requirement

- satisfied: The objective has been completely satisfied.
- not-satisfied: The objective has not been completely satisfied, but may be partially satisfied.
description The reason the objective was given it's status.
Remarks
Reason may contain any value, and should be used to communicate additional information regarding the status.
Constraint (1)
allowed values
The value may be locally defined, or one of the following:
- pass: The target system or system component satisfied all the conditions.
- fail: The target system or system component did not satisfy all the conditions.
- other: Some other event took place that is not a pass or a fail.
Remarks
The implementation-status
is used to qualify the status
value to indicate the degree to which the control was found to be implemented.
description Describes a function performed for a given authorized privilege by this user class.
description A group of controls, or of groups of controls.
Remarks
Catalogs can use a group
to collect related controls into a single grouping. That can be useful to group controls
into a family or other logical grouping.
A group
may have its own properties, statements, parameters, and references, which are inherited
by all members of that group.
Constraint (1)
allowed values for prop/@name
The value may be locally defined, or one of the following:
- label: A human-readable label for the parent context.
- sort-id: An alternative identifier, whose value is easily sortable among other such values in the document.
Properties (8)
description A unique identifier for a specific group instance that can be used to reference the group within this and in other OSCAL documents. This identifier's uniqueness is document scoped and is intended to be consistent for the same group across minor revisions of the document.
description A textual label that provides a sub-type or characterization of the group.
Remarks
A class
can be used in validation rules to express extra constraints over named items of
a specific class
value.
A class
can also be used in an OSCAL profile as a means to target an alteration to control
content.
description A name given to the group, which may be used by a tool for display and navigation.
group as params
use name param
Remarks
In a catalog, a parameter is typically used as a placeholder for the future assignment
of a parameter value, although the OSCAL model allows for the direct assignment of
a value if desired by the control author. The value
may be optionally used to specify one or more values. If no value is provided, then
it is expected that the value will be provided at the Profile or Implementation layer.
A parameter can include a variety of metadata options that support the future solicitation
of one or more values. A label
provides a textual placeholder that can be used in a tool to solicit parameter value
input, or to display in catalog documentation. The desc
provides a short description of what the parameter is used for, which can be used
in tooling to help a user understand how to use the parameter. A constraint
can be used to provide criteria for the allowed values. A guideline
provides a recommendation for the use of a parameter.
group as props
use name prop
Remarks
Properties permit the deployment and management of arbitrary controlled values, within OSCAL objects. A property can be included for any purpose useful to an application or implementation. Typically, properties will be used to sort, filter, select, order, and arrange OSCAL content objects, to relate OSCAL objects to one another, or to associate an OSCAL object to class hierarchies, taxonomies, or external authorities. Thus, the lexical composition of properties may be constrained by external processes to ensure consistency.
Property allows for associated remarks that describe why the specific property value was applied to the containing object, or the significance of the value in the context of the containing object.
group as links
Remarks
To provide a cryptographic hash for a remote target resource, a local reference to
a back matter resource
is needed. The resource allows one or more hash values to be provided using the rlink/hash
object.
The OSCAL link
is a roughly based on the HTML link element.
group as parts
Remarks
A part
provides for logical partitioning of prose, and can be thought of as a grouping structure
(e.g., section). A part
can have child parts allowing for arbitrary nesting of prose content (e.g., statement
hierarchy). A part
can contain prop
objects that allow for enriching prose text with structured name/value information.
A part
can be assigned an optional id
, which allows for internal and external references to the textual concept contained
within a part
. A id
provides a means for an OSCAL profile, or a higher layer OSCAL model to reference
a specific part within a catalog
. For example, an id
can be used to reference or to make modifications to a control statement in a profile.
Use of part
and prop
provides for a wide degree of extensibility within the OSCAL catalog model. The optional
ns
provides a means to qualify a part's name
, allowing for organization-specific vocabularies to be defined with clear semantics.
Any organization that extends OSCAL in this way should consistently assign a ns
value that represents the organization, making a given namespace qualified name
unique to that organization. This allows the combination of ns
and name
to always be unique and unambiguous, even when mixed with extensions from other organizations.
Each organization is responsible for governance of their own extensions, and is strongly
encouraged to publish their extensions as standards to their user community. If no
ns
is provided, the name is expected to be in the "OSCAL" namespace.
To ensure a ns
is unique to an organization and naming conflicts are avoided, a URI containing a
DNS or other globally defined organization name should be used. For example, if FedRAMP
and DoD both extend OSCAL, FedRAMP will use the ns
"https://fedramp.gov", while DoD will use the ns
"https://defense.gov" for any organization specific name
.
Tools that process OSCAL content are not required to interpret unrecognized OSCAL extensions; however, OSCAL compliant tools should not modify or remove unrecognized extensions, unless there is a compelling reason to do so, such as data sensitivity.
group as groups
Remarks
Catalogs can use a group
to collect related controls into a single grouping. That can be useful to group controls
into a family or other logical grouping.
A group
may have its own properties, statements, parameters, and references, which are inherited
by all members of that group.
group as controls
Remarks
Controls may be grouped using group
, and controls may be partitioned using part
or further enhanced (extended) using control
.
A control must have a part with the name "statement", which represents the textual narrative of the control. This "statement" part must occur only once, but may have nested parts to allow for multiple paragraphs or sections of text.
description A group of (selected) controls or of groups of controls
Remarks
This construct mirrors the same construct that exists in an OSCAL catalog.
Properties (8)
description A unique identifier for a specific group instance that can be used to reference the group within this and in other OSCAL documents. This identifier's uniqueness is document scoped and is intended to be consistent for the same group across minor revisions of the document.

Remarks
A class
can be used in validation rules to express extra constraints over named items of
a specific class

Properties (5)
description A reference to a component that is implemented as part of an inventory item.
use name prop
group as props
Remarks
Properties permit the deployment and management of arbitrary controlled values, within OSCAL objects. A property can be included for any purpose useful to an application or implementation. Typically, properties will be used to sort, filter, select, order, and arrange OSCAL content objects, to relate OSCAL objects to one another, or to associate an OSCAL object to class hierarchies, taxonomies, or external authorities. Thus, the lexical composition of properties may be constrained by external processes to ensure consistency.
Property allows for associated remarks that describe why the specific property value was applied to the containing object, or the significance of the value in the context of the containing object.
group as links
Remarks
To provide a cryptographic hash for a remote target resource, a local reference to
a back matter resource
is needed. The resource allows one or more hash values to be provided using the rlink/hash
object.
The OSCAL link
is a roughly based on the HTML link element.
group as responsible-parties
Remarks
This construct is used to either: 1) associate a party or parties to a role defined
on the component using the responsible-role
construct, or 2) to define a party or parties that are responsible for a role defined
within the context of the containing inventory-item
.
description The date and time the document was last modified. The date-time value must be formatted according to RFC 3339 with full time and time zone included.
Remarks
This value represents the point in time when the OSCAL document was last updated, or at the point of creation the creation date. Typically, this date value will be machine generated at time of creation or modification.
In some cases, an OSCAL document may be derived from some source material in a different
format. In such a case, the last-modified
value should indicate the modification time of the OSCAL document, not the source
material.
A publisher of OSCAL content can use this data point along with its siblings published
and version
to establish a sequence of successive revisions of a given OSCAL-based publication.
The metadata for previous revisions can be represented as a revision
in this object.
description A reference to a local or remote resource
Remarks
To provide a cryptographic hash for a remote target resource, a local reference to

resource
in the same document.
If a local reference using a fragment is used, this will be indicated by a fragment
"#" followed by an identifier which references an identified resource
in the document's back-matter
or another object that is within the scope of the containing OSCAL document.
If an internet resource is used, the href
value will be an absolute or relative URI pointing to the location of the referenced
resource. A relative URI will be resolved relative to the location of the document
containing the link.
description Describes the type of relationship provided by the link. This can be an indicator of the link's purpose.
Constraint (1)

Remarks
Properties permit the deployment and management of arbitrary controlled values, within OSCAL objects. A property can be included for any purpose useful to an application or implementation. Typically, properties will be used to sort, filter, select, order, and arrange OSCAL content objects, to relate OSCAL objects to one another, or to associate an OSCAL object to class hierarchies, taxonomies, or external authorities. Thus, the lexical composition of properties may be constrained by external processes to ensure consistency.
Property allows for associated remarks that describe why the specific property value was applied to the containing object, or the significance of the value in the context of the containing object.
group as links
Remarks
To provide a cryptographic hash for a remote target resource, a local reference to
a back matter resource
is needed. The resource allows one or more hash values to be provided using the rlink/hash
object.
The OSCAL link
is a roughly based on the HTML link element.
group as parts
Remarks
A part
provides for logical partitioning of prose, and can be thought of as a grouping structure
(e.g., section). A part
can have child parts allowing for arbitrary nesting of prose content (e.g., statement
hierarchy). A part
can contain prop
objects that allow for enriching prose text with structured name/value information.
A part
can be assigned an optional id
, which allows for internal and external references to the textual concept contained
within a part
. A id
provides a means for an OSCAL profile, or a higher layer OSCAL model to reference
a specific part within a catalog
. For example, an id
can be used to reference or to make modifications to a control statement in a profile.
Use of part
and prop
provides for a wide degree of extensibility within the OSCAL catalog model. The optional
ns
provides a means to qualify a part's name
, allowing for organization-specific vocabularies to be defined with clear semantics.
Any organization that extends OSCAL in this way should consistently assign a ns
value that represents the organization, making a given namespace qualified name
unique to that organization. This allows the combination of ns
and name
to always be unique and unambiguous, even when mixed with extensions from other organizations.
Each organization is responsible for governance of their own extensions, and is strongly
encouraged to publish their extensions as standards to their user community. If no
ns
is provided, the name is expected to be in the "OSCAL" namespace.
To ensure a ns
is unique to an organization and naming conflicts are avoided, a URI containing a
DNS or other globally defined organization name should be used. For example, if FedRAMP
and DoD both extend OSCAL, FedRAMP will use the ns
"https://fedramp.gov", while DoD will use the ns
"https://defense.gov" for any organization specific name
.
Tools that process OSCAL content are not required to interpret unrecognized OSCAL extensions; however, OSCAL compliant tools should not modify or remove unrecognized extensions, unless there is a compelling reason to do so, such as data sensitivity.
description A location, with associated metadata that can be referenced.
Constraints (3)
allowed value for prop/@name
The value may be locally defined, or the following:
- type: Characterizes the kind of location.
allowed value for prop[@name='type']/@value
The value may be locally defined, or the following:

allowed values for prop[@name='type' and @value='data-center']/@class
The value may be locally defined, or one of the following:
- primary: The location is a data-center used for normal operations.
- alternate: The location is a data-center used for fail-over or backup operations.
Properties (9)
description A unique identifier that can be used to reference this defined location elsewhere in an OSCAL document. A UUID should be consistently used for a given location across revisions of the document.
description A name given to the location, which may be used by a tool for display and navigation.
Remarks
Typically, the physical address of the location will be used here. If this information is sensitive, then a mailing address can be used instead.
group as telephone-numbers
value key number
Remarks
A phone number used to contact the location.
description The uniform resource locator (URL) for a web site or Internet presence associated with the location.
group as urls
group as props

Remarks
Properties permit the deployment and management of arbitrary controlled values, within OSCAL objects. A property can be included for any purpose useful to an application or implementation. Typically, properties will be used to sort, filter, select, order, and arrange OSCAL content objects, to relate OSCAL objects to one another, or to associate an OSCAL object to class hierarchies, taxonomies, or external authorities. Thus, the lexical composition of properties may be constrained by external processes to ensure consistency.

description Used to indicate who created a log entry in what role.
Properties (2)
description A pointer to the party who is making the log entry.
description A point to the role-id of the role in which the party is making the log entry.
description Specifies a media type as defined by the Internet Assigned Numbers Authority (IANA) Media Types Registry.
description A Merge element merges controls in resolution.
Remarks
The contents of the merge
element may be used to reorder
or restructure
controls by indicating an order and/or structure in resolution.
Implicitly, a merge
element is also a filter: controls that are included in a profile, but not included
(implicitly or explicitly) in the scope of a merge
element, will not be merged into (will be dropped) in the resulting resolution.
Properties (2)
Remarks
Whenever combining controls from multiple (import) pathways, an issue arises of what to do with clashing invocations (multiple competing versions of a control).
This setting permits a profile designer to apply a rule for the resolution of such cases. In a well-designed profile, such collisions would ordinarily be avoided, but this setting can be useful for defining what to do when it occurs.
Remarks
The custom
element represents a custom arrangement or organization of controls in the resolution
of a catalog.
While the as-is
element provides for a restitution of a control set's organization (in one or more
source catalogs), this element permits the definition of an entirely different structure.

Properties (14)
description A name given to the document, which may be used by a tool for display and navigation.
Remarks
This value represents the point in time when the OSCAL document was published. Typically, this date value will be machine generated at the time the containing document is published.
In some cases, an OSCAL document may be derived from some source material in a different
format. In such a case, the published
value should indicate when the OSCAL document was published, not the source material.
Where necessary, the publication date of the original source material can be captured
as a named property or custom metadata construct.
A publisher of OSCAL content can use this data point along with its siblings last-modified
and version
to establish a sequence of successive revisions of a given OSCAL-based publication.
The metadata for previous revisions can be represented as a revision
in this object.
Remarks
This value represents the point in time when the OSCAL document was last updated, or at the point of creation the creation date. Typically, this date value will be machine generated at time of creation or modification.

Remarks
A version string may be a release number, sequence number, date, or other identifier suffcient to distinguish between different document versions. This version is typically set by the document owner or by the tool used to maintain the content.
While not required, it is recommended that OSCAL content authors use Semantic Versioning as a format for version strings. This allows for the easy identification of a version tree consisting of major, minor, and patch numbers.
A publisher of OSCAL content can use this data point along with its siblings published
and last-modified

Remarks
Indicates the version of the OSCAL model to which this data set conforms, for example
1.1.0
or 1.0.0-M1
. That can be used as a hint by a tool to indicate which version of the OSCAL XML
or JSON schema to use for validation.
group as revisions
Remarks
While published

items must be provided: published
, last-modified
, version
, or a link
with a rel
of source
.
group as document-ids
value key identifier
Remarks
This element is optional, but it will always have a valid value, as if it is missing the value of "document-id" is assumed to be equal to the UUID of the root. This requirement allows for document creators to retroactively link an update to the original version, by providing a document-id on the new document that is equal to the uuid of the original document.
group as props

Remarks
Use @control-id
to indicate the scope of alteration.
It is an error for two alter
elements to apply to the same control. In practice, multiple alterations can be applied
(together), but it creates confusion.
At present, no provision is made for altering many controls at once (for example, to systematically remove properties or add global properties); extending this element to match multiple control IDs could provide for this.

description The OSCAL model version the document was authored against.
Remarks
Indicates the version of the OSCAL model to which this data set conforms, for example
1.1.0
or 1.0.0-M1
. That can be used as a hint by a tool to indicate which version of the OSCAL XML
or JSON schema to use for validation.
description Parameters provide a mechanism for the dynamic assignment of value(s) in a control.
use name param
Remarks
In a catalog, a parameter is typically used as a placeholder for the future assignment
of a parameter value, although the OSCAL model allows for the direct assignment of
a value if desired by the control author. The value
may be optionally used to specify one or more values. If no value is provided, then
it is expected that the value will be provided at the Profile or Implementation layer.
A parameter can include a variety of metadata options that support the future solicitation
of one or more values. A label
provides a textual placeholder that can be used in a tool to solicit parameter value
input, or to display in catalog documentation. The desc
provides a short description of what the parameter is used for, which can be used
in tooling to help a user understand how to use the parameter. A constraint
can be used to provide criteria for the allowed values. A guideline
provides a recommendation for the use of a parameter.
Properties (11)
description A unique identifier for a specific parameter instance. This identifier's uniqueness is document scoped and is intended to be consistent for the same parameter across minor revisions of the document.
description A textual label that provides a characterization of the parameter.
Remarks
A class
can be used in validation rules to express extra constraints over named items of
a specific class
value.
group as props
use name prop
Remarks
Properties permit the deployment and management of arbitrary controlled values, within OSCAL objects. A property can be included for any purpose useful to an application or implementation. Typically, properties will be used to sort, filter, select, order, and arrange OSCAL content objects, to relate OSCAL objects to one another, or to associate an OSCAL object to class hierarchies, taxonomies, or external authorities. Thus, the lexical composition of properties may be constrained by external processes to ensure consistency.
Property allows for associated remarks that describe why the specific property value was applied to the containing object, or the significance of the value in the context of the containing object.
group as links
Remarks
To provide a cryptographic hash for a remote target resource, a local reference to
a back matter resource
is needed. The resource allows one or more hash values to be provided using the rlink/hash
object.
The OSCAL link
is a roughly based on the HTML link element.
description A short, placeholder name for the parameter, which can be used as a substitute for
a value
if no value is assigned.
Remarks
The label value should be suitable for inline display in a rendered catalog.
description Describes the purpose and use of a parameter
use name value
group as values
Remarks
A set of values provided in a catalog can be redefined at any higher layer of OSCAL (e.g., Profile).
use name select
Remarks
A set of parameter value choices, that may be picked from to set the parameter value.
A set of parameter value choices, that may be picked from to set the parameter value.
description A reference to a parameter within a control, who's catalog has been imported into the current implementation context.
description A formal or informal expression of a constraint or test
Properties (2)
description A textual summary of the constraint to be applied.
description A test expression which is expected to be evaluated by a tool.
group as tests
Properties (2)
description A formal (executable) expression of a constraint
description A prose statement that provides a recommendation for the use of a parameter.
Property (1)
description Prose permits multiple paragraphs, lists, tables etc.
description Presenting a choice among alternatives
Remarks
A set of parameter value choices, that may be picked from to set the parameter value.
Properties (2)
description Describes the number of selections that must occur. Without this setting, only one value should be assumed to be permitted.
Constraint (1)
allowed values
The value must be one of the following:
- one: Only one value is permitted.
- one-or-more: One or more values are permitted.
description A value selection among several such options
use name choice
value key value
group as choice
description A parameter value or set of values.
description A partition of a control's definition or a child of another part.
Remarks
A part
provides for logical partitioning of prose, and can be thought of as a grouping structure
(e.g., section). A part
can have child parts allowing for arbitrary nesting of prose content (e.g., statement
hierarchy). A part
can contain prop
objects that allow for enriching prose text with structured name/value information.
A part
can be assigned an optional id
, which allows for internal and external references to the textual concept contained
within a part
. A id
provides a means for an OSCAL profile, or a higher layer OSCAL model to reference
a specific part within a catalog
. For example, an id
can be used to reference or to make modifications to a control statement in a profile.
Use of part
and prop
provides for a wide degree of extensibility within the OSCAL catalog model. The optional
ns
provides a means to qualify a part's name
, allowing for organization-specific vocabularies to be defined with clear semantics.
Any organization that extends OSCAL in this way should consistently assign a ns
value that represents the organization, making a given namespace qualified name
unique to that organization. This allows the combination of ns
and name
to always be unique and unambiguous, even when mixed with extensions from other organizations.
Each organization is responsible for governance of their own extensions, and is strongly
encouraged to publish their extensions as standards to their user community. If no
ns
is provided, the name is expected to be in the "OSCAL" namespace.
To ensure a ns
is unique to an organization and naming conflicts are avoided, a URI containing a
DNS or other globally defined organization name should be used. For example, if FedRAMP
and DoD both extend OSCAL, FedRAMP will use the ns
"https://fedramp.gov", while DoD will use the ns
"https://defense.gov" for any organization specific name
.
Tools that process OSCAL content are not required to interpret unrecognized OSCAL extensions; however, OSCAL compliant tools should not modify or remove unrecognized extensions, unless there is a compelling reason to do so, such as data sensitivity.
Constraints (4)
allowed values for prop/@name
The value may be locally defined, or one of the following:
- label: A human-readable label for the parent context.
- sort-id: An alternative identifier, whose value is easily sortable among other such values in the document.

allowed values for prop[@name='method']/@value
The value must be one of the following:
- INTERVIEW: The process of holding discussions with individuals or groups of individuals within an organization to once again, facilitate assessor understanding, achieve clarification, or obtain evidence.
- EXAMINE: The process of reviewing, inspecting, observing, studying, or analyzing one or more assessment objects (i.e., specifications, mechanisms, or activities).
- TEST: The process of exercising one or more assessment objects (i.e., activities or mechanisms) under specified conditions to compare actual with expected behavior.

, so that different organizations and individuals can assert control over the allowed
names and associated text used in a part. This allows the semantics associated with
a given name to be defined on an organization-by-organization basis.
An organization MUST use a URI that they have control over. e.g., a domain registered to the organization in a URI, a registered uniform resource names (URN) namespace.

. This can be used to further distinguish or discriminate between the semantics of
multiple parts of the same control with the same name
and ns
.
Remarks
A class
can be used in validation rules to express extra constraints over named items of
a specific class
value.
A class
can also be used in an OSCAL profile as a means to target an alteration to control
content.
description A name given to the part, which may be used by a tool for display and navigation.

description Each OSCAL profile is defined by a Profile element
root name profile
Remarks
An OSCAL document that describes a tailoring of controls from one or more catalogs,
with possible modification of multiple controls. It provides mechanisms by which controls
may be selected (import
), merged or (re)structured (merge
), and amended (modify
). OSCAL profiles may select subsets of controls, set parameter values for them in
application, and even adjust the representation of controls as given in and by a catalog.
They may also serve as sources for further modification in and by other profiles,
that import them.
Properties (6)
description A globally unique identifier for this profile instance. This UUID should be changed when this document is revised.
group as imports
Remarks
A profile must be based on an existing OSCAL catalog or another OSCAL profile. An
import
indicates such a source whose controls are to be included (referenced and modified)
in a profile. This source will either be a catalog whose controls are given (by value
), or a profile with its own control imports.
The contents of the import
element indicate which controls from the source will be included. Controls from the
source catalog or profile may be either selected, using the include-all
or include-controls
directives, or de-selected (using an exclude-controls
directive).
Remarks
The contents of the merge
element may be used to reorder
or restructure
controls by indicating an order and/or structure in resolution.
Implicitly, a merge
element is also a filter: controls that are included in a profile, but not included
(implicitly or explicitly) in the scope of a merge
element, will not be merged into (will be dropped) in the resulting resolution.
Remarks
Provides a collection of identified resource
objects that can be referenced by a link
with a rel
value of "reference" and an href
value that is a fragment "#" followed by a reference to a reference identifier. Other
specialized link "rel" values also use this pattern when indicated in that context
of use.

Properties (6)
description A textual label that uniquely identifies a specific attribute, characteristic, or quality of the property's containing object.
Constraint (1)
allowed value
The value may be locally defined, or the following:
- marking: A label or descriptor that is tied to a sensitivity or classification marking system. An optional class can be used to define the specific marking system used for the associated value.
description A unique identifier that can be used to reference this property elsewhere in an OSCAL document. A UUID should be consistently used for a given location across revisions of the document.
description A namespace qualifying the property's name. This allows different organizations to associate distinct semantics with the same name.
Remarks
Provides a means to segment the value space for the name
, so that different organizations and individuals can assert control over the allowed
names and associated values used in a property. This allows the semantics associated
with a given name/value pair to be defined on an organization-by-organization basis.
An organization MUST use a URI that they have control over. e.g., a domain registered to the organization in a URI, a registered uniform resource names (URN) namespace.
When a ns
is not provided, its value should be assumed to be http://csrc.nist.gov/ns/oscal
and the name should be a name defined by the associated OSCAL model.
description Indicates the value of the attribute, characteristic, or quality.
description A textual label that provides a sub-type or characterization of the property's name
. This can be used to further distinguish or discriminate between the semantics of
multiple properties of the same object with the same name
and ns
.
Remarks
A class
can be used in validation rules to express extra constraints over named items of
a specific class
value.
description Information about the protocol used to provide a service.
Properties (4)
description A globally unique identifier that can be used to reference this service protocol entry elsewhere in an OSCAL document. A UUID should be consistently used for a given resource across revisions of the document.
description The common name of the protocol, which should be the appropriate "service name" from the IANA Service Name and Transport Protocol Port Number Registry.
Remarks
The short name of the protocol (e.g., https).
description A human readable name for the protocol (e.g., Transport Layer Security).
group as port-ranges
Remarks
To be validated as a natural number (integer >= 1). A single port uses the same value for start and end. Use multiple 'port-range' entries for non-contiguous ranges.
description Identifies a 'provided' assembly associated with this assembly.
description The date and time the document was published. The date-time value must be formatted according to RFC 3339 with full time and time zone included.
Remarks
This value represents the point in time when the OSCAL document was published. Typically, this date value will be machine generated at the time the containing document is published.
In some cases, an OSCAL document may be derived from some source material in a different
format. In such a case, the published
value should indicate when the OSCAL document was published, not the source material.
Where necessary, the publication date of the original source material can be captured
as a named property or custom metadata construct.
A publisher of OSCAL content can use this data point along with its siblings last-modified
and version
to establish a sequence of successive revisions of a given OSCAL-based publication.
The metadata for previous revisions can be represented as a revision
in this object.
description Identifies an individual task for which the containing object is a consequence of.

Remarks
In the context of an assessment plan, this construct is used to identify the controls and control objectives that are to be assessed. In the context of an assessment result, this construct is used to identify the actual controls and objectives that were assessed, reflecting any changes from the plan.
When resolving the selection of controls and control objectives, the following processing will occur:
1. Controls will be resolved by creating a set of controls based on the control-selections by first handling the includes, and then removing any excluded controls.
2. The set of control objectives will be resolved from the set of controls that was generated in the previous step. The set of control objectives is based on the control-objective-selection by first handling the includes, and then removing any excluded control objectives.
The Assessment Results control-selection
ignores any control selection in the Assessment Plan and re-selects controls from
the baseline identified by the SSP.
The Assessment Results control-objective-selection
ignores any control objective selection in the Assessment Plan and re-selects control
objectives from the baseline identified by the SSP.
Any additional control objectives defined in the Assessment Plan local-definitions
do not need to be re-defined in the Assessment Results local-definitions
; however, if they were explicitly referenced with an Assessment Plan control-objective-selection
, they need to be selected again in the Assessment Results control-objective-selection
.
description A set of textual statements, typically written by the assessor.

Constraint (1)
is unique for responsible-party
: any target value must be unique (i.e., occur only once)
Properties (2)
group as responsible-parties
use name part
use name part
group as parts
Remarks
A part
provides for logical partitioning of prose, and can be thought of as a grouping structure
(e.g., section). A part
can have child parts allowing for arbitrary nesting of prose content (e.g., statement
hierarchy). A part
can contain prop
objects that allow for enriching prose text with structured name/value information.
A part
can be assigned an optional id
, which allows for internal and external references to the textual concept contained
within a part
. A id
provides a means for an OSCAL profile, or a higher layer OSCAL model to reference
a specific part within a catalog
. For example, an id
can be used to reference or to make modifications to a control statement in a profile.
Use of part
and prop
provides for a wide degree of extensibility within the OSCAL catalog model. The optional
ns
provides a means to qualify a part's name
, allowing for organization-specific vocabularies to be defined with clear semantics.
Any organization that extends OSCAL in this way should consistently assign a ns
value that represents the organization, making a given namespace qualified name
unique to that organization. This allows the combination of ns
and name
to always be unique and unambiguous, even when mixed with extensions from other organizations.
Each organization is responsible for governance of their own extensions, and is strongly
encouraged to publish their extensions as standards to their user community. If no
ns
is provided, the name is expected to be in the "OSCAL" namespace.
To ensure a ns
is unique to an organization and naming conflicts are avoided, a URI containing a
DNS or other globally defined organization name should be used. For example, if FedRAMP
and DoD both extend OSCAL, FedRAMP will use the ns
"https://fedramp.gov", while DoD will use the ns
"https://defense.gov" for any organization specific name
.
Tools that process OSCAL content are not required to interpret unrecognized OSCAL extensions; however, OSCAL compliant tools should not modify or remove unrecognized extensions, unless there is a compelling reason to do so, such as data sensitivity.

Remarks
Properties permit the deployment and management of arbitrary controlled values, within OSCAL objects. A property can be included for any purpose useful to an application or implementation. Typically, properties will be used to sort, filter, select, order, and arrange OSCAL content objects, to relate OSCAL objects to one another, or to associate an OSCAL object to class hierarchies, taxonomies, or external authorities. Thus, the lexical composition of properties may be constrained by external processes to ensure consistency.
