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 gary On 4/5/2011 11:46 PM, Andre Merzky wrote:

Maybe I wasn't clear with the question. I thought we generated a scheme and published it on http://schemas.ogf.org . It been almost a year ago, so I may be wrong... or dropped another brain cell along the way :) From what I understand from the OCCI specs, the schema locations are indeed supposed to provide a unique and well defined namespace for OCCI, and OCCI extensions. But I don't see any place in the specs where that URL is actually evaluated, and returns a schema of any kind.
Having said that, I think it might be a good idea to use that schema scheme (ha!) to implement some form of namespace verification. For example, I placed an empty document at http://schemas.ogf.org/occi/infrastructure, so that all GET operations on that document return an HTTP 200 (OK). That provides a very simple way to confirm the validity of OCCI identifiers, and also provides a straight-forward way to register OCCI extensions (or rather, their namespaces). One could also link the normative documents for the extension at http://schemas.ogf.org/occi/infrastructure#specification; one could verify the #target elements; etc. However, that is as of yet unspecified AFAICS, and is likely a rather naive proposal, given my somewhat limited knowledge of HTTP itself.
Best, Andre.
cheers, gary

(Same question in the core document , with regards to the http://schemas.ogf.org/occi/ base URL reserved for OCCI and the http://schemas.ogf.org/occi/core#entity Kind instances.)
Sorry for the ignorant question.

More specifically - in Table 1 we define the following Kind instances. Are these tken to be a namespace, so that no definite schema has to be associated with them, or is there intended to be a document returned at the following URIs (i.e., are they actual schemata URLs)?
Table 1. The Kind instances defined for the infrastructure sub-types of Resource, Link and related Mixins. The base URL http://schemas.ogf.org/occi has been replaced with<schema> in this table for a better readability experience.

What would you expect to see there?
