Steve, The rdf:type should be the OSLC type defined by the appropriate domain spec, e.g. CM. It belongs to the OSLC domain, http://open-services.net, so GETing it would NOT reflect any new properties added by a service provider.
I agree that it would be handy to be able to easily find the shape of a resource. There are really two major use cases: 1. Schema-based information, e.g. to design a report. You need to find the shape from the service provider. This is what oslc:shape is for. 2. Instance-based information, e.g. you are given the URL of an instance resource and you want to find its shape, e.g. to modify the instance via PUT. There is no property defined yet. Using oslc:shape might be confusing. In XML Schema, they introduced a special namespace for instance level information such as type, xsi: http://www.w3.org/2001/XMLSchema-instance. To avoid confusion I suggest we use a different property, e.g. oslc:instanceShape Regards, ___________________________________________________________________________ Arthur Ryman, PhD, DE Chief Architect, Project and Portfolio Management IBM Software, Rational Markham, ON, Canada | Office: 905-413-3077, Cell: 416-939-5063 Twitter | Facebook | YouTube From: Steve K Speicher <[email protected]> To: [email protected] Date: 04/24/2010 03:06 PM Subject: [oslc-core] How do I get the shape from a resource? Sent by: [email protected] I had assumed that every OSLC defined resource would have an rdf:type property that references either the spec defined Type URI OR is it a gettable URI that references the service provider's hosted version of the resource shape. Here's my example, I have a OSLC-CM Change Request resource that looks like: <oslc_cm:ChangeRequest rdf:about="http://example.com/bugs/2314";> <rdf:type rdf:reference=" http://open-services.net/xmlns/cm/2.0#ChangeRequest";> </oslc_cm:ChangeRequest> Is it required for rdf:type to point to the OSLC defined Type URI? How do I get to the resource shape of this resource? I would instead think that we'd want an OSLC Common Property called "oslc:shape" which points to a gettable OSLC shape resource. Any objections to adding this? Any need use dc:type here instead (or clarify how it could be used) ?
