in between position

Hi,

As a SPIN and ICV user myself, I have no objections in standardising nor SPIN nor a closed world semantics OWL.
I have no opinions yet on ShEx since not studied.

But what we as implementation partner encounter doing jobs (mainly linked data in the government domain) is that both SPIN and ICV are very difficult to sell. 
The reasons might be different (perceived as difficult, overloading the system, OWL being already closed in the minds of people).

So if there would come along a constraint language death simple (with escape route to SPARQL) that would get my vote also.
