ATProto Lexicons

Create a lexicon for concept schemes in general.

Crib from the RDF ecosystem, which has more or less figured this out.

Determine the extent to which Lexicon and RDF are isomorphic, or at least that the expressive range of Lexicon is a subset of the range of RDF.

If SKOS is portable to Lexicon, could other RDF vocabularies also be portable?

Is there prior art we can use for a concept scheme lexicon?

Port SKOS (RDF) to ATProto Lexicon.

SKOS concepts are identifiable, addressable data objects which are distinct from their labels.

SKOS is a stable ontology and its proponents have already fairly exhaustively plumbed the problem space.

SKOS is already deployed in e.g. content management systems.

The topology of SKOS is set-theoretic rather than strictly hierarchical, which is much less restrictive and more enlightened take on organizing information.
