Aspect ModelsAspect Model A formal, machine-readable semantic description (expressed with RDF/Turtle) of data accessible from an aspect. Note 1: An Aspect Model must adhere to the Semantic Aspect Meta Model (SAMM) and be compliant with its validity rules. Note 2: Aspect Models are logical data models that can be used to detail a conceptual model to describe the semantics of runtime data related to a concept; elements of an Aspect Model can/should refer to terms of a standardized Business Glossary (if existing). with the namespace urn:samm:io.catenax. MUST be maintained and released in Eclipse Tractus-X: SLDT-Semantic-Models.

Every semantic model used in any of the Catena-X Standards MUST have a unique identifier conformant to the meta model identifiers definition in SAMM. For the semantic models developed in the scope of Catena-X the unique identifier MUST start with either

urn:samm:io.catenax.

or

urn:samm.io.admin-shell.idta.batterypass.

Note 1: An Aspect Model must adhere to the Semantic Aspect Meta Model (SAMM) and be compliant with its validity rules.

For the current version of the Semantic Aspect Meta Model under consideration see CX-0003, normative references.

For the currently used version of the Validator see information in Readme. Newer versions of the validator can be used but need an explicit decision and -- if needed -- a migration path of all existing and released Aspect ModelsAspect Model A formal, machine-readable semantic description (expressed with RDF/Turtle) of data accessible from an aspect.
