Syndication Format from Google: Gdata

Search Engine Watch pointed me to a new Google data API, GData:

The Google data APIs (“GData” for short) provide a simple standard protocol for reading and writing data on the web. GData combines common XML-based syndication formats (Atom and RSS) with a feed-publishing system based on the Atom publishing protocol, plus some extensions for handling queries.

The big enhancement to its format, says Google is that it allows clients to query and get responses from a server. You can even add to, delete or update Web resources via GData. (I think those are called transactions, based on my limited understanding of Web services.)

My first thoughts are that this is a good idea. My second is that I want to be able to query about location. I’ve been reading up on GeoRSS and I hope there’s a way to incorporate its ideas into GData.
