Initiated page with definition of content metamodels, and our specific usage/standard at SSC.
A content metamodel defines a set of entities that allow architectural concepts to be captured, stored, filtered, queried, and represented in a way that supports consistency, completeness, and traceability. (TOGAF 9: 30.2.2)

Our content metamodel is based largely on the TOGAF 9.2 and (primarily) on the ArchiMate 3.0.1 specification, with some specific adaptations and alignment for SSC. In general, unless specified, any relationship permitted in ArchiMate 3.0.1 is permitted.
