Hi, I have finished and uploaded a rather significant update of the Core & Models [1] document. The Infrastructure document [2] has been updated accordingly while the HTTP Rendering document is still in the works. The Core & Models changelog: - Updated UML diagram. Fixes the issue with Actions. - Updated and re-structured description/definition of the base types. Please read everything through. - Templates definition added, it is just a Category but without the requirement to be a type construct. - Added full description of the Category base type. - Removed all REST and HTTP stuff. This information will reappear in the HTTP Rendering document. - HTTP related Open Issues will reappear in the HTTP Rendering document. - Extension rules properly defined. - Discovery mechanism from the Core perspective. Hopefully the new version should be a lot more consistent and only address things relevant to the Core specification. The information which was specific to the HTTP rendering will reappear in that document when it is completed. I put some effort into describing how to extend OCCI Core so each base type now has its on subsection describing the rules for domain-specific extensions. Comments welcome. regards, Ralf [1] http://forge.ogf.org/sf/wiki/do/viewPage/projects.occi-wg/wiki/CoreAndModels [2] http://forge.ogf.org/sf/wiki/do/viewPage/projects.occi-wg/wiki/Infrastructur...
