>From RFC4287: 1. Introduction Atom is an XML-based document format that describes lists of related information known as "feeds". Feeds are composed of a number of items, known as "entries", each with an extensible set of attached metadata. For example, each entry has a title. I understand it as "if the set/list of entries is different, this is not the same feed", as is the case with a "filtered version". I know this is subject to debate, as later on, the RFC reads: An Atom Feed Document is a representation of an Atom feed, including metadata about the feed, and some or all of the entries associated with it. Its root is the atom:feed element. Given that there's no mandatory way of getting "all of the entries with" a feed, you cannot really compare two feed documents (or two sets of feed documents) to determine whether they represent the same feed or not. My opinion however is that a "filtered version" of a feed is a new feed; and Google should mint new atom:id's for GData's search result feeds. -- Thomas Broyer
