PlatPhorm Metadata Header Stamp

A PlatPhorm Metadata Header Stamp is a PlatPhorm News dictionary concept for making PlatPhorm stories portable across RSS, Atom, APIs, and article cards. It treats the top-level story metadata block as a structured article-listing or network-graph concern, and it marks when the feed item changed. In practice, it helps editors, services, and AI agents keep title, canonical URL, source, image, summary, and timestamps aligned across every listing surface.

“Use the PlatPhorm Metadata Header Stamp when serializing a story into RSS while keeping its canonical article URL and preview image intact so the article listing, source metadata, and agent-facing context stay aligned.”
