Within a project area, I can see a creationFactory with an associated list of resourceShapes that are types /rm/types/$id.   These types appear to be all the artifact types.    Each one of those /rm/types/id when fetched produces a list of oslc:property.   The name and valueType are recognized as attributes appearing in my artifacts, including the custom attributes I set up in a new artifact type; OK.
Problem:   There's no indication of the name of the artifact type; thus, I cannot narrow the set of attributes that are relevant to a particular NAMED artifact (as opposed to using the ID).

So...  can anyone articulate how to get fetch the oslc:property tuples (i.e. all the attribute defs) for a SINGLE NAMED artifact type in RM?

Are you looking for a way to identify which named artifact type does the resource shape belong to, on a resource shape URI?

I don't see a way to do that directly without doing a get on the resource shape URI. But the result of GET on resource shape URI does have a tuple that would allow you to identify which named artifact type's properties they are, along with the bunch of oslc:properties it gets:

<dc:title rdf:parseType="Literal">Feature</dc:title>

Funny how when you step away and then look again, you see it.   Yes, the dc:title is in fact in there as a peer item to the oslc:property items (which irritatingly enough are not wrapped as a collection similar to other calls).   For some reason I simply did not see it before. So I whipped it up and now it works.   I get the resourceShapes from the creationFactory, then iterate over them, ignoring all but the dc:title of the desired artifact type.   Functionally OK but there can be a performance hit, especially since my custom artifacts tend to end up at the BOTTOM of the list.   Thanks.
