| Realm | uv |
| Description | 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. |
