That is indeed my understanding: the object of a hanging @rel is a fully
formed "entity", with a subject and triples of its own.

More importantly, using @resource to complete a hanging @rel brings back
the @instanceof confusion of my earlier proposal: does @instanceof apply
to @about or @resource, and why? At the time, I thought the confusion
was justified because it enabled a bunch of use cases.

Here, however, this enables no new use cases. And, as I've stated before
it requires additional parser rules, not fewer.

All the example you've written, Mark, can be easily rewritten by writing
@about instead of @resource.

So, I don't see the point of complicating things.
