The following is a reference for the JSON object definitions derived from the metaschema for this model.
Short name oscal-ap
JSON Base URI http://csrc.nist.gov/ns/oscal
Remarks
The OSCAL assessment plan format is used to describe the information typically provided by an assessor during the preparation for an assessment.
The root of the OSCAL assessment plan format is assessment-plan.
description Identifies an assessment or related process that can be performed. In the assessment plan, this is an intended activity which may be associated with an assessment task. In the assessment results, this an activity that was actually performed as part of an assessment.
Constraints (4)
allowed value for prop/@name
The value may be locally defined, or the following:
- method: The assessment method to use. This typically appears on parts with the name "assessment".
has cardinality for prop[@name='method'] the cardinality of prop[@name='method'] is constrained: 1; maximum unbounded.
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.

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.

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.

use name 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.
description An assessment plan, such as those provided by a FedRAMP assessor.

- rules-of-engagement: Defines the circumstances, conditions, degree, and manner in which the use of cyber-attack techniques or actions may be applied to the assessment.
- disclosures: Any information the assessor should make known to the system owner or authorizing official. Has child 'item' parts for each individual disclosure.
- assessment-inclusions: Defines any assessment activities which the system owner or authorizing official wishes to ensure are performed as part of the assessment.
- assessment-exclusions: Defines any assessment activities which the system owner or authorizing official explicitly prohibits from being performed as part of the assessment.
- results-delivery: Defines conditions related to the delivery of the assessment results, such as when to deliver, how, and to whom.
- assumptions: Defines any supposition made by the assessor. Has child 'item' parts for each assumption.
- methodology: An explanation of practices, procedures, and rules used in the course of the assessment.
Property (1)
group as parts
use name 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.
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.

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.

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.

Properties (6)
Remarks
The specified control-id must be a valid value within the baseline identified by the target system's SSP via
the import-profile statement.
description A human-readable description of this control objective.
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.

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.
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.
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 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
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, last-modified, oscal-version, and version are not required, values for these entries should be provided if the information
is known. For a revision entry to be considered valid, at least one of the following
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
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.

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.

description A namespace qualifying the part'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 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.
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 A textual label that uniquely identifies the part's semantic type.
Constraint (1)
allowed values
The value may be locally defined, or one of the following:
- overview: An introduction to a control or a group of controls.
- statement: A set of control implementation requirements.
- item: An individual item within a control statement.
- guidance: Additional information to consider when selecting, implementing, assessing, and monitoring a control.
- objective: Describes a set of assessment objectives.
- assessment: Describes a method-based assessment over a set of assessment objects.
- objects: Provides a list of assessment objects.
description A namespace qualifying the part'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 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.
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 A textual label that provides a sub-type or characterization of the part's name. 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.
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.
description Permits multiple paragraphs, lists, tables etc.
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.

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.

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-roles
Remarks
Identifies the person or organization responsible for performing a specific role defined by the activity.
use name subject
group as subjects
Remarks
Processing of an include/exclude pair starts with processing the include, then removing matching entries in the exclude.

description A string used to distinguish the current version of the document from other previous (and future) versions.
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 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.
