Nice work, it fits in to the current use of categories while making extensibility easier to understand. A few comments/questions: Each category, defined by schema + term, can have a set of associated attributes. What namespace restrictions/rules are imposed on these attributes? Currently Core&Models says provider defined categories must be in a different namespace but no more. Maybe extend this a bit further as to avoid namespace conflicts while combining many categories? I believe earlier revs of the spec said something like: com.example.<category_term>.<attr_name> I do not quite understand the various Content-type headers used in the examples. Are they of any significance to the definition/use of categories? And just a few notes on the examples, sorry if it sounds picky but consistency really helps understanding: - Category: compute; scheme="http://prov.com/occi#"; Scheme should be "http://prov.com/occi/resource#" right? - Link: </compute/123-123-123;start>; type="application/occi-action"; Is the "type" attribute of the Link header something new? If so, how it is defined? - In Link header: rel="category http://prov.com/occi#action" Is the format rel="category XXX" something new as well? regards, Ralf On Fri, 13 Aug 2010 11:10:18 +0200, Edmonds, AndrewX <andrewx.edmonds@intel.com> wrote:
Hi all, Yesterday Alexander and I spent some time exploring and discussing OCCI categories. These categories make up the type system for OCCI and I've documented our discussion here [1]. We'd love to hear feedback, comments etc!
