Lexicons
Every schema Lexicon Community publishes, by namespace. These are the areas of responsibility it stewards: collectively owned, MIT licensed, and usable by any application, system, or SDK on the AT Protocol.
Published NSIDs resolve through the dedicated
@lexicons.lexicon.community repository, which holds
exactly the published schema records; this page is generated from
it. Per-schema documentation lives on
Lexicon Garden, an independent lexicon browser and validator, and the schema
sources live in
the lexicons repository. If you build with one of these namespaces and want to get
involved, see
Contributing.
