S3Model Has Moved - Now Semantic Data Charter

Thank you for visiting. S3Model has been rebranded and significantly enhanced as the Semantic Data Charter (SDC4).

What's Changed?

The Semantic Data Charter represents the evolution of S3Model into a comprehensive, standards-based specification for semantic data modeling, built on 16+ international standards from W3C, ISO, and IETF.

For readers of our peer-reviewed publications: All S3Model research, concepts, and specifications have been integrated into the Semantic Data Charter with enhanced capabilities and broader standards compliance.
