Hi Mike!

I agree with you the Zthes is closer from a perfect solution than a 
simple sortkey added to the concept itself.

Does this mean that, in a way, the NTs of a given concept are an 
implicit collection that is (or not) ordered?
And that this depends of the concept: is it a concept generalizing its 
NTs with an implicit ranking axis?
Is it something like "Historical period", "Wheeled vehicles", 
"Orchestral formation type" (solo, duo, quatuor, sextuor, etc.), etc.

So my proposal, if one day we decide to improve SKOS, would be to enrich 
the description of concepts to indicate this.

So one field stating "Does the concept "order" its NTs?" ?
     or a subproperty of "narrower": "orderedNarrower" ?
      And also "narrowMatch" specialized with "orderedNarrowMatch"?

As we cannot mix skos:existingProperty with skos:desiredProperty:
* Who could manage a namespace for properties that the community is 
putting under scrutiny and that one or the other may want to implement?
* Where the resulting "additions" RDFS file could be deposited?

Have a nice day!

Christophe

P.S. Other metadata I would like to add to a concept:
* Is it "natural" (directly linked to users knowledge) or "artificial" 
(created by the thesaurus manager for concept organization purpose)?
    (I would make "artificial" concepts disappear from displays in some 
circumstances)
* What is the concept status in the management workflow? (to know if it 
should be displayed or not to a given user)

For a Scheme: is it a (complete) inventory of possible values? is it a 
list, a classification or a hierarchical thesaurus?
   This would also allow to improve display and automated reuse of schemes.
