Semantic Hub

Glossary Page

Semantic models play a vital role in organizing data, providing a foundational understanding of data and its interconnections. In the context of data modeling and organization, semantic models facilitate the seamless development of applications and ensure data consistency. In the Catena-X framework, semantic data models are accessible through a well-suited publishing system called the Semantic Hub. For data and service providers, the Semantic Hub acts as a platform for leveraging and reusing semantic models. As a result, the publication of a semantic data model includes the specification of a version, enhancing transparency and enabling control over all semantic models and their release status.
