Blogging Roller

APP draft #10 is available. I'm still reading it over, but the major changes appear to be:

• Categories can be specified at the workspace and collection level. Multiple category schemes are allowed and both fixed and free-form categories (e.g. tags) are allowed.
• Collection titles are now specified by an <atom:title> instead of an attribute on the <collection> element.
• A new "slug" header has been added for media posts so that clients can specify the file-name to be used for the uploaded file.

I'm especially happy about the category support -- now Atom protocol can do everything that MetaWeblog API can do, and much more. I'll be updating my client and server implementations during the next week.
