We are trying to use resource shapes to advertise metadata about resources types that can be queried by OSLC clients. However, the description in the table in the OSLC Core spec seems to indicate a different usage, which is not clear:
"oslc:resourceShape zero-or-one ... The Query Capability SHOULD provide a Resource Shape that describes the query base URI. " Is the intent that a query capability can only be used to query for instances of a single type of resource, since "occurs" is zero-or-one? Also, not clear what is meant by "a Resource Shape that describes the query base URI." We thought that the Resource Shape would be used to describe the resources that are managed by the provider and can be searched/retrieved using the query URL. If not, then it's not clear where we can expose that metadata to clients. This other paragraph later on in the specification seems to describe the use that we intended: "An OSLC Service may provide one or more Query Capabilities to enable query of resources. A Query Capability provides a base URI for forming Query Resource URIs and MAY provide Resource Shapes that describe the property values that may be expected in the resources that are queryable via the query capability. Thus, Query Capabilities provide a way to discover the resources managed by an OSLC Service. " This seems to indicate that there can be multiple resource shapes for a query capability and that they describe properties of the resources being managed by the provider. Which of these is correct?
