A Predicate is a sentence forming Relation. Thus, you can effectively 
group RDF relations by Predicate scoped to a Named Graph IRI, if you 
choose. Naturally, you can also apply other forms of ordering, en route 
to effect UI/UX.

You can describe collections using RDF statements, I don't have any idea 
how what I am talking about implies collection exclusion.

Why do you think we've built an RDF editor without factoring in OWL?

Sorta.

There is no perfect view. You simply need a view to enables:

1. coherent data curation
2. provides the user with choices in regards to how items are categorized.


I think we are better off waiting until we release our RDF Editor. We 
actually built this on the request of a vary large customer. This isn't 
a speculative endeavor. It's actually being used by said organization as 
I type....

We've opted (we didn't have to) to make it Open Source too.
