I gather it's all over but the crying for the Atom publishing
format. Congrats!

Meanwhile, I'm seeing something of a syndication trend in
a bunch of recent announcements from W3C members:


December 2004

We currently use XHTML and RSS/RDF to syndicate our news.

Some relevant points in W3C's history:

The design space around things like the google sitemap
were discussed at this workshop:

Distributed Indexing/Searching Workshop 
 May 28-19, 1996 in Cambridge, Massachusetts
 http://www.w3.org/Search/9605-Indexing-Workshop/

And we had CDF and the push workshop:

 March 1997 CDF submission
 http://www.w3.org/TR/NOTE-CDFsubmit.html

 September 1997 push workshop
 http://www.w3.org/Architecture/9709_Workshop/

An more recently:

TAG issue siteData-36 accepted 23 Feb 2003
http://www.w3.org/2001/tag/issues.html?type=1#siteData-36


I get questions occasionally about how W3C and IETF relate in
this space, so I thought I'd share at least the background facts
that I'm aware of here, and see if any helpful discussion
results.
