[SKOS] About Closing ISSUE-36 ConceptSchemeContainment

Hello all,

Sorry for opening again a can of worm, but I have some doubts about the 
process of closing this issue...
During last telconf, we agreed on the following resolution for ISSUE-36 
ConceptSchemeContainment [1]:

> RESOLUTION: skos:inScheme is not deprecated, skos:inScheme is not a
>     subproperty of rdfs:isDefinedBy. In accordance [3] can be kept, but
>     adding inScheme in the proposed vocabulary as well as domain and 
> range
>     statements for this property. It should also include the following
>     sentence: "The SKOS Primer also defines best practices for using
>     skos:inScheme to explicitly state the relationship between a SKOS
>     conceptual resource and the concept scheme(s) to which it belongs."
>
>     The general idea is "we let the opportunity of using rdfs:isDefinedBy
>     for some purposes open, but skos:inScheme is clearly what is 
> needed for
>     concept scheme membership and we keep it in the SKOS language".

I would like before closing the issue to make sure that member of the WG 
are aware of the fact that *this reolution brings only a partial 
solution to the issue*.
As part of the issue reads on [1]:

> SKOS relationships such as broader and narrower are represented as triples in
> RDF. The fact that a particular broader/narrower relationship between two
> concepts belongs to a concept scheme cannot then be represented without
> resorting to reification.
>
> A principled approach to representing this containment would be desirable.
>   

This aspect is not dealt with by the above resolution, which deals only 
with containment of Concepts.
Would this formally prevent us to CLOSE the issue?

To CLOSE I feel that we should record somewhere we don't want to tackle 
with containment of semantic relationships (as well as documentation and 
label one).
I can be OK with this, but I think this solution is actually not what 
the WG is thinking of. In some of our discussion on Concept Schemes and 
OWL ontologies (cf action on this [4]) there is still the notion of 
containment for relations.
My feeling is thus that  we have to see what happens for [4] before 
definitively CLOSING ISSUE-36. What do you think?

Cheers,

Antoine
