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.

BMWE2025: From silos to ecosystems

The Federal Ministry for Economic Affairs and Energy’s conference “From Silos to Ecosystems – Creating Europe’s Digital Momentum” (Berlin, 5–6 Nov 2025) highlighted Europe’s unique opportunity to lead in industrial data ecosystems powered by dataspace technology. While Europe may not compete at scale in general-purpose foundation models, it holds a strategic advantage in sovereign, cross-industry data sharing. Keynotes and panels emphasized the urgency of data readiness, with Oliver Ganser (BMW, Catena‑X) calling for accelerated adoption to maintain Europe’s lead. Practical workshops showcased initiatives such as Manufacturing‑X, Industrial AI, and the IPCEI on Cloud Infrastructure and Services, while RoX demonstrated early prototypes for AI‑based robotics dataspaces. The event underscored that Europe’s digital momentum will hinge on scaling industrial ecosystems, anchoring them in local clusters, and expanding across supply chains to unlock new growth opportunities.
