Logical Model: Terminology Syndication Feed

Official URL: https://ontoserver.csiro.au/syndication/StructureDefinition/syndication-feed Version: 0.1.0
Draft as of 2026-06-29 Computable Name: SyndicationFeed

An Atom 1.0 feed (RFC 4287) used to syndicate terminology releases.

The default XML namespace is http://www.w3.org/2005/Atom. Feeds that use the NCTS ASF profile additionally declare the ncts: namespace and SHOULD include the ⟨ncts:atomSyndicationFormatProfile⟩ element identifying the profile version.

A feed is an ordered collection of entries (RFC 4287 §4.1). Order is publisher-defined; consumers MUST NOT rely on order to determine recency — use the entry-level updated element instead.
