Semantic models in Catena-X are predefined data structures that are particularly suitable for the automotive industry. Semantic models offer all network participants the advantage of being able to work with consistent, secure and comprehensible structures.
Semantic models offer the possibility of mapping both physical objects (e.g. machine components) and virtual objects. Virtual objects can be, for example, contact information or other data for which no “tangible” object exists in reality.
Examples of semantic models in the Sematic Hub
Semantic Model | Suitable for |
EndOfLife | Aspect for End of Life Story for the Dismantler. |
PartAsSpecified | The aspect model PartAsSpecified belongs to the Part Catalogue. A PartAsSpecified represents a certain OEM catalog part on part number level. Providing a digital representation of the part as specified by the OEM. The link to the serialized part is done via the partId, this can only be done if the respective DT was provided by the supplier within the value chain. |
The semantic models are used in the submodels. The submodels are therefore the “data” of the object to be described.
The industry-standard semantic models are provided in the Semantic Hub in the Cofinity-X portal. In addition, further semantic models can be obtained from the TRACTUSX association (see https://github.com/eclipse-tractusx/sldt-semantic-models).
An “asset” is used to share the data of the submodel with others. The asset contains a static link to the corresponding submodel.
