Semantic Data Model (Ontology)
Depending on the use case and related KIT, Catena-X provides different semantic models that help to structure and make use of data via semantic information. These models help to provide a basic meaning to the data and their relationship, thereby enabling interoperability between data sets. Catena-X data models rely on principles as understandability, standardization, accuracy, differentiation, audibility, comprehensiveness, and provision of insights to drive improvement actions.
In an era defined by growing environmental consciousness and sustainability imperatives, the concept of measuring and reducing carbon footprints has become paramount across industries. A pivotal key in this pursuit is an aligned and standardized PCF data model. This data model not only facilitates the systematic calculation and comparison of carbon footprints but also offers a structured approach to managing environmental impact data.
As the global community grapples with the impacts of climate change, consumers, businesses, and governments are seeking actionable ways to mitigate their carbon emissions. The need for a consistent and universally accepted method of quantifying these emissions from diverse products has given rise to the significance of a standardized PCF data model. This model acts as a lingua franca, enabling stakeholders to communicate and analyze carbon footprint information transparently and comprehensively.
For this KIT only the PCF data model is used. The PCF data model follows the CX-0136 Use Case PCF standard and is implemented in compliance with the CX-0003 SAMM Aspect Meta Model standard.
The Catena-X PCF data model has been developed in accordance with the "Technical Specifications for PCF Data Exchange" from the WBCSD (World Business Council for Sustainable Development)/ PACT initiative. The basis for the specification of the Catena-X PCF data model is the PCF Rulebook v3.0.0.
The following illustration describes the logical structure of the Catena-X PCF data model:
