      "description": "An anchor in the t0ronto data commons: a bare, claim-free identity for a thing — an organization, programme, venue, neighbourhood, or a vocabulary concept. The anchor holds NO properties of its own. Everything true of it — name, type, topics, location, prefLabel, broader, alignments — is asserted by separate com.t0ronto.commons.statement records, which may be authored by many different DIDs. The anchor exists only to mint a stable, resolvable identity that statements point at. Whether an anchor denotes a real-world thing or a vocabulary concept is itself an attestation (an `instanceOf` statement, e.g. instanceOf skos:Concept), not a property of this record or of which collection it lives in. The rkey IS the entity's stable identifier: a UUIDv7 for real-world things (mapping 1:1 to the public URL t0ronto.ca/e/<uuid>) or a curated slug for vocabulary concepts (e.g. at://<did>/com.t0ronto.commons.entity/music).",
