Nick Crossley commented on OSLCCORE-48:
---------------------------------------

I agree that if the new shape describes only part of the resource - just the extension properties and not the base properties - then using oslc:describes and a new type would not be appropriate. In that case, it would be better to add a new predicate (oslc:extends?).

> Many of the existing OSLC domain vocabularies are fairly simple, defining a relatively small number of RDFS classes, and rarely (if ever) use subClassOf. As a result an instance of a domain class can have an oslc:instanceShape that references a simple ResourceShape.
> However, some vocabularies, such as those derived from UML, SysML, PLE, etc. may have much richer vocabularies that have deep inheritance hierarchies. Although it is possible to create A ResourceShape for each subclass, this would result in a very large number of repeated properties as the properties inherited from superclasses would need to be copied down into the ResourceShape for each subclass in order to fully specify the resource shape. 
> I is therefore desirable to have some means of "inheriting" constraints from some other ResourceShape(s), or extend a ResourceShape with constraints defined in some other shape - a chain of constraints like prototypes in JavaScript.
