| Draft as of 2026-06-29 | Computable Name: SyndicationFeedMetadata | ||||
A reduced description of a feed, used inside an entry's
⟨source⟩ element (Atom RFC 4287 §4.2.11).
When an entry is copied, mirrored, or aggregated from one feed into
another, the receiving feed SHOULD preserve the originating feed's
identity by including a ⟨source⟩ element on the entry. The
⟨source⟩ element carries enough metadata to recover the
originating feed even if the entry is later detached from any feed
document.
A consumer that re-encounters the same entry ⟨id⟩ in two
different feeds can use ⟨source⟩ to disambiguate origin.
