About RSSid.com

Mission

RSSid.com explains how publishers and software can keep syndication identity stable while URLs, hosts, formats, and metadata change. The site focuses on practical implementation: canonical feed URLs, item identifiers, discovery markup, validation, migration evidence, and transparent registry models.

Scope and independence

This is an independent educational reference. It is not an official standards body, podcast directory, ownership registry, or live feed resolver. Standards and vendor documentation are linked where they directly support an article, while architecture recommendations are presented as implementation guidance.

Editorial approach

Each Identity Log article addresses one distinct operational problem, uses stable terminology, links to one authoritative external source, and cross-references related internal guides. Claims about formats are checked against specifications or official publisher documentation. The site does not publish invented usage statistics, rankings, partnerships, or testimonials.

Formats covered

The reference covers RSS 2.0, Atom, JSON Feed, and podcast RSS. It also discusses HTTP redirects, HTML autodiscovery, XML namespaces, feed fingerprints, and API contracts where they affect identity and interoperability.
