[occi-wg] Where is the scheme ?

Wed Apr 6 01:17:46 CDT 2011

Hi Andre,

Thanks..

I did find the reference to it in one of your emails from 2 years 
ago..Minor comments:

        - why the purl.org/occi namespace? OGF has an established
        namespace for XML schemata, see http://schemas.ogf.org/,
        and GFD.84 on http://www.ogf.org/docs/?cp

cheers
