Abstract:

   Independently written systems that anchor records to a SCITT
   Transparency Service repeatedly re-derive the same construction: a
   canonical form of structured content, a content-addressed identifier
   derived from that form, a receipt placed in the unprotected header of
   the Signed Statement, and a typed reference mechanism that lets one
   record cite another by digest across profile boundaries.  This
   document defines that construction as a reusable profile — the
   Canonical Payload Binding — so that each payload class declares its
   canonicalization algorithm and exclusion set once, obtains an
   interoperable derived identifier, and inherits statement-to-receipt
   binding and typed digest reference semantics without restating the
   mechanics in every profile.  It complements the COSE Hash Envelope
   mechanism defined in RFC 9995: where that mechanism signals that a
   Signed Statement's payload is a digest standing in for content held
   elsewhere, this document defines how that digest is computed from
   structured content so that independently written implementations
   converge on the same bytes.  An IANA registry governs the
   canonicalization algorithms; entries are immutable.  This document
   defines no payload content formats and registers no artifact types;
   the artifact types that a typed reference may cite, and their
   meaning, are registered in a single shared Artifact Type Registry,
   governed separately from this document, that payload profiles
   register into.
