Yes, you are correct and I made a mistake. I removed the
oslc:describes property without properly raising an issue on the
issues page. Somebody pointed out that shapes should not be tied to
types, which I thought was consensus, I dropped that property and then
forgot to raise/document it with an issue.

I just added it back, but I do wonder: do we really want to tie
resource types to shapes?

Back to the topic at hand...

With oslc:describes, there is a way to enable clients to
programmatically select a Creation Factory and a Query Capability.

But perhaps we are not quite there yet. Once a Creation Factory is
selected, a client would then have to select a Resource Shape. There
could be multiple Resource Shapes that describe any one OSLC defined
resource type, e.g. Task, Defect, Issue and Story shapes for a Change
Request. How does a client select a shape?
