Smart Data Models\u2019 Candidates repository<\/a> now includes a new candidate standard translated from the Catena-X semantic models<\/strong>: catena-x-semantic-models<\/code><\/strong>, with 8 candidate models<\/strong> from the Catena-X Industry Core, the traceability backbone of the automotive data space. The source models are published under CC-BY-4.0<\/strong>. Like every candidate, each model comes with a JSON Schema, an NGSI-LD @context<\/code> and all four example serializations (NGSI-v2 and NGSI-LD, key-values and normalized), each validated against its schema.<\/p>\n

About the Catena-X semantic models<\/h2>\n

Catena-X<\/a> is the data space of the automotive industry. Its shared vocabulary is a set of aspect models<\/strong> written in SAMM, the Semantic Aspect Meta Model, and published by the Catena-X Automotive Network through the Eclipse Tractus-X project in the sldt-semantic-models<\/a> repository. Each aspect describes one view of a digital twin, such as a serialized part, its bill of material or its product carbon footprint. All the aspects of a twin share one identifier, the globalAssetId<\/code>. The repository holds about 150 aspect models. This first candidate covers the Industry Core<\/strong>, the eight aspects that every Catena-X traceability use case builds on, in their current versions (the io.catenax.industry_core<\/code> namespaces introduced in release 26.09).<\/p>\n

Examples from the Tractus-X reference data<\/h2>\n

Real Catena-X data is exchanged between companies under usage policies and is not public. The examples therefore come from the Eclipse Tractus-X reference test data set used by the Item Relationship Service, which forms consistent twin trees. A \u201cDoor front-left\u201d serial part, its as-built bill of material and its as-built usage describe the same twin, and its child is the just-in-sequence part \u201cMirror left\u201d. On the planning side, an \u201cOEM A High Voltage Battery\u201d part type is planned into a \u201cVehicle Model A\u201d. The test data uses older aspect versions, so each record was updated to the current version using the renames in each model\u2019s release notes.<\/p>\n
