CodeSystem: Ontoserver RF2 Binary Index Category

Official URL: http://ontoserver.csiro.au/syndication/rf2 Version: 0.1.0
Draft as of 2026-05-09 Computable Name: OntoserverRf2Index

The single category term used by syndication entries that publish a pre-built Ontoserver RF2 binary index — i.e. a zip file containing the on-disk index Ontoserver builds from a SNOMED CT RF2 release, ready to be consumed directly without re-indexing.

Consumers that recognise this artefact type can load the index directly; consumers that do not MUST ignore the entry (the artefact is not a SNOMED CT RF2 release).

Wire-level scheme URI

On the wire, the Atom ⟨category⟩ element's scheme attribute carries one of these URIs — not the canonical of this CodeSystem:

  • http://ontoserver.csiro.au/syndication/rf2/1.0.0
  • http://ontoserver.csiro.au/syndication/rf2/2.0.0

The trailing path segment is the binary index format version — not the version of the SNOMED CT release contained in the index. A consumer MUST match the scheme URI exactly: an index published as …/rf2/1.0.0 is not interchangeable with one published as …/rf2/2.0.0.

The label paired with this term on the ⟨category⟩ element is conventionally Binary Index.
