A Google search for "atom publishing protocol" lists the top several results as:
- Atom Publishing Format and Protocol (atompub) Charter - historically important and it has a link to the spec itself, but that's about it
- the atom publishing protocol - version 11 of IETF draft spec in text format, the latest normative version
- Joe Gregorio | BitWorking | Projects | Atom - Joe's work-in-progress page, probably the most useful link if you're looking for the latest spec
- The Atom Publishing Protocol - version 4(!?) of the draft spec in HTML format, hosted on Joe's site
- XML.com: Catching Up with the Atom Publishing Protocol" - a good article written by Joe a year ago
- XML.com: Implementing the Atom Publishing Protocol - a more recent article, also by Joe
- ietf-atompub-protocol-11.txt - the Internet Society's copy of the latest draft. (Is this site considered normative?)
Further down we get a few other important links, such as FrontPage - Atom Wiki, the wiki on Sam's site that started it all, and AtomEnabled / Developers / Atom API, a page on the the website that gets the top result for "atom" (on this topic).
So the question is: if you had to pick, which link would be first on a search for "atom publishing protocol"? Would it be one of the above?
Or would it be a site specifically designed for that purpose?
Frankly, atompub.org is a great candidate. Even in its current simple form it's already a good gateway to more information, which is all this site needs to be. But who knows if Robert Sayre, who registered and hosts the domain wants to take this project on right now. If not, perhaps it could be donated to the cause?
And for reference: links to searches for atom pub and atompub. All over the map, really. You know a term is not clearly defined when mailing list posts start popping up in the top few search results...
