Atom Feed Summary

Atom’s explicit IDs, timestamps, link relations, and content types make it a strong input for structured feed summary workflows.

Atom strengths

Why Atom is useful for summary systems

Atom provides explicit semantics that reduce several common ingestion ambiguities.

Required identity

Entries carry IDs that support source-scoped update tracking.

Link relations

Alternate, self, related, and enclosure links can remain distinct.

Typed content

Text, HTML, XHTML, and external content are declared rather than guessed.

Normalization

Map Atom without losing semantics

A normalized record should remember which Atom construct supplied each value.

Dates and people

Keep `published` and `updated` separate. Preserve multiple authors and contributor roles. Do not infer publication time from update time when the feed omits it.

Store the original timestamp string and normalized UTC value.

Content and links

Process content according to its declared type, resolve base URIs, and retain every meaningful link relation. Select the alternate page link deliberately.

Keep XHTML structure until it has been converted into ordered content blocks.

Record design

Atom in a multi-format pipeline

The downstream summarizer should receive the same core record as RSS and JSON Feed.
