A snapshot in time comparison of the Metaschema Java and XSLT-M4 implementations' schema generation for usnistgov/metaschema#317.

Comparing Generated OSCAL Scheams from Java and XSLT-M4

Methodology

• develop from usnistgov/OSCAL with metaschema submodule @ ``
• oscal-cli version 0.3.1 was used at this time with current metaschemas from develop branch of usnistgov/OSCAL.

JSON Schema

• Object names for sub-schemas (i.e. xslt-M4: oscal-complete-oscal-catalog:catalog: vs. metaschema-java: OscalCatalogCatalogAssemblyType)
• XSLT-M4 schema generation prefixes the schema "strategy" as a prefix whereas metaschema-java does not (i.e. oscal-complete-oscal-catalog:catalog: vs. metaschema-java: OscalCatalogCatalogAssemblyType)
• $ref structures are different (i.e. in xslt-M4: "$ref": "#/definitions/UUIDDatatype" versus the same with metaschema-java is "#/definitions/OscalCatalogCatalogUuidFlagType")
