The AUGMANITAI Concept Registry: A Public, Versioned, Author-Attributed Concept Registry — Reference Implementation of the Universal Concept Layer (v0.1)

Whitepaper on the AUGMANITAI Concept Registry — a public, versioned, author-attributed concept registry, live at augmanitai.com/registry/ as the reference implementation of the Universal Concept Layer (v0.1, bilingual English/German). Agent ecosystems are standardising transport, discovery and identity. The meaning level — what a term means, how its meaning changes over versions, and who coined it — has no public, versioned, cross-organisational infrastructure. This paper describes the design principles (terms as versioned artefacts with semantic versioning: MAJOR = break in meaning, MINOR = refinement, PATCH = wording; stable GET-addressable records; mandatory author attribution; evidence anchors per concept), the data model with schema, and the live reference implementation covering six signature concepts, each resolvable as JSON.
