W3C Feed Validation Service compared with Podbase and Validome
W3C Feed Validation Service	Podbase	Validome
Formats checked: RSS 0.90, 0.91, 0.92, 0.93, 0.94, 1.0 and 2.0, plus Atom 1.0 checked against the IETF draft that preceded the RFC. Atom validation targets that draft until the IETF assigns a number.	Formats checked: Checks that the XML is well formed and that the feed is iTunes compatible.	Formats checked: A general validator that also handles HTML, XHTML, WML, XML, DTD, Schema and Google Sitemaps. For feeds it covers RSS and Atom, including Atom 0.3 and 1.0, according to a 2006 description.
Extension and podcast checks: Only a fixed list of namespaces is validated: blogChannel, Dublin Core, itunes, mod_admin, mod_syndication and mod_content (content:encoded only). Podcast tags outside the itunes namespace are not covered.	Extension and podcast checks: Goes further on podcast metadata: it also reviews cover art compliance, category and summary.	Extension and podcast checks: A 2006 description states that RSS 0.91 feeds with a DOCTYPE are not supported and that RSS 1.0 extensions are not verified as RDF/XML. It warns when the Atom MIME type is not used for Atom feeds.
Input and interfaces: You enter the URL of a feed. A SOAP 1.2 interface is available by adding output=soap12 to the query. A downloadable test suite of almost 1,000 feeds is provided.	Input and interfaces: You enter the feed URL. Apple lists it among external validators for troubleshooting a failed podcast validation.
Maintenance and openness: The validator software is open source Python and is not developed at W3C. It was designed by Mark Pilgrim, with much of the back end written by Sam Ruby. Bugs go to the GitHub project and feedback to the public www-validator list.
