Fieldnotes
Focused explorations of one architectural question and the tradeoff behind it.
Why a Semantic Space has both an RID and an RSN
Why each Semantic Space carries a registered name and a separate permanent identifier, and what goes wrong when either is mistaken for the other — or for the server.
Why an RID should not encode its meaning
Why an RID carries no type, place, owner, or host — and why the meaning-rich parts live in names and metadata that are allowed to change.
Why identity is not ownership
Why RSM ID keeps issuance authority, legal ownership, custody, and stewardship as separate relationships — and what would break if it did not.
Why resolution is not simply fetching a document
Why RSM ID resolution verifies authority, evaluates lifecycle and disclosure, and negotiates a representation instead of following a link to a file.
Why semantic equivalence is not identity equality
Why RSM ID never merges identities on similarity, sameAs claims, or shared source files — and what an authorized equivalence decision needs instead.
