[occi-wg] OCCI Categories and Types

[Ralf Nyren]

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
