OSID - osid.resource.Resource Service Interface Definition

Interface	osid.resource.Resource

A provider may present such a group in an opaque manner through a single resource definition, or the provider may expose the resource collection for examination or manipulation. If such a resource collection is visible, `isGroup()` is `true` and can be used in one of the group sessions available in this OSID.
