(registered 2026-08-06, last updated 2026-11-03) Scheme name: cm Status: Provisional Applications/protocols that use this scheme name: A cm URI is a domain-free identifier (no host, no "//") that names a stable, local-scope referent, unique within its namespace. Its form is cm::/, with the components of a gdsi URI. Its structure and semantics are defined by the specification (in preparation). Any cm URI shown in referenced material is a non-normative example only. Contact: Jan Zdráhal Change controller: Jan Zdráhal References: No permanent specification is cited at the provisional stage. Per RFC 7595 a citable specification is required only for permanent registration; the credible reasons for deferring it are (1) reference stability - the name is reserved under FCFS so that cm URIs already shown as non-normative examples have a stable, unambiguous namespace while the defining specification is finalized; and (2) definitional stability - permanent registration fixes the scheme's semantics, and the definition's scope is still being closed, so a permanent definition would lock in semantics prematurely. The registration will be updated to Permanent, with a citable specification, upon publication.
