The core idea
A well-defined article record can serve a website card, a topic archive, and a feed entry without maintaining three competing copies of the facts. Preserve the distinction between the full body, a short excerpt, and a derived summary. They serve different reading situations and may need separate review.
A workable starting pattern
Assign an identifier before publication and choose one canonical destination. Keep visible and machine-readable dates together. When a correction changes the article, review its excerpt and related summaries as well. Use tags to explain the main subject rather than mirror every phrase in the body.
A guide to RSS validation could have a short card excerpt and a full-text feed representation. Both point to the same canonical article and use the same reviewed category, even though their displayed length differs.
