# OSCAL Profile Schema

`src/oscal/schema/oscal_profile.yaml` is the module titled "OSCAL Profile Model", with the id `https://w3id.org/lmodel/oscal/oscal_profile`.[^oscal_profile.yaml] Its `version` is `1.2.3`, its license Apache-2.0, and its `source` is NIST's JSON schema of the model, `http://csrc.nist.gov/ns/oscal/1.2.3/oscal-profile-schema.json`. It imports `linkml:types` and the [catalog module](oscal-catalog-schema.md). Its `see_also` names NIST's page on the profile, <https://pages.nist.gov/OSCAL/learn/concepts/layer/control/profile/>.

The README describes the profile model as a selection of controls from catalogs, and how it alters them.[^readme.md] `Profile` is "An OSCAL Profile that designates a set of controls from one or more catalogs or profiles, optionally restructures and modifies them, to describe a basis for a security standard or body of practice". It requires `uuid`, `metadata` and `imports`, and also holds `merge`, `modify` and `back-matter`. `ProfileDocument` wraps one profile as the root of a profile document.

The module's one subset, `profile`, holds the root document and its profile-specific containers: `ProfileImport`, the merge classes `ProfileMerge`, `CombinationRule`, `MergeFlat` and `MergeCustom`, and the modification classes `ProfileModify`, `ParameterSetting`, `Alteration`, `Removal` and `Addition`, among others.
