[occi-wg] Model attributes and category attributes

[Ralf Nyren]

Hi,

The update of the core model introduced (at least) 3 new categories within  
the core scheme, http://schemas.ogf.org/occi/core# :

http://schemas.ogf.org/occi/core#resource
http://schemas.ogf.org/occi/core#link
http://schemas.ogf.org/occi/core#action

(The core&model page still use the purl.org scheme urls, update needed)

These categories are not defined (as e.g. the resources in the  
infrastructure document) and thus it is not yet entirely clear which set  
attributes are associated with the categories.  The link category is  
likely to define "occi.link.source", "occi.link.target" for example.

We also have hard-coded attributes in the model, the "title" attribute of  
Kind, "id" and "summary" of Resource, etc.

In short there are two ways an attribute can be defined.

Which attributes of the core types should be static and which should be  
defined by categories? What criteria should determine where an attribute  
is defined? E.g. should Link source/target be defined in the model or by  
http://schemas.ogf.org/occi/core#link?

regards, Ralf
