About the BIM Dictionary

The BIM Dictionary is the canonical, editorial home for BIMei Terms: the shared vocabulary of Building Information Modelling and the wider digital built environment.

Permanent identifiers

Every term has a permanent identifier you can cite and link to with confidence:

https://w3id.org/bimei/term/{slug}

A term's identity does not depend on language, region or version. Labels and definitions are given for each language and, where they differ, for each region, while the term keeps one stable identity.

A source of truth, not a live service

Other tools and ontologies take a versioned snapshot of the dictionary's terms rather than calling it live, so what they cite stays fixed.
