I think in the context of Atom you'd have to leave that to the applications at the end of the line. I imagine it should be possible to use Atom Protocol to maintain and synchronise such structures. > I strongly suggest that we come out a list of use cases and that would > make the discussion and decision much easier. I would put forward: server-side categorization as provided by blogging tools, where the user either adds arbitrary tags or builds a tree of labels; bibliographic style categorization, where the entries are associated with standard categorizations. > e.g. will the autodiscovery prompts user the available feeds of > different categories, or allow user choose which categories to subscribe? That sounds feasible, though probably quite tricky. > Somehow I feel the tags used by flickr and delicious is good enough. I believe PaceCategoryRevised will allow simple tagging : <category term="animals" /> possibly more personal: <category term="animals" scheme="http://myexampleblog.com"; /> as well as more a more standardised approach: <category term="animals" scheme="http://flickr.com"; /> a bit richer: <category term="Dog-2" scheme="http://xmlns.com/wordnet/1.6/"; label="Dog" /> Cheers, Danny. -- http://dannyayers.com
