Here’s an update from the validator formerly known as the RSS Validator and now known as the Feed Validator:
The validator is now known as the “Feed Validator”, because it now supports multiple syndication formats with different names. (Previously it only supported the seven different formats called “RSS”.) Specifically, there is now preliminary support for Pie, based on the July 1 snapshot. As the format evolves, the validator will be updated to support it.
Sweet! Check out what’s new for the new version of the validator:
It includes 225 new test cases for Pie, as well as the existing 326 test cases for RSS.
This is definately a step in the right direction. It’s good to have an authoritative answer on what consititutes a good feed, be it RSS, RDF, or pie (not echo).
