Hi,

Here is a revised proposal for handling subject indicators in SKOS Core,
based on Bernard's suggestion:

Add the following property:

 - subjectIndicatorRef

Additionally: 

(1) the property skos:subjectIndicatorRef is defined by reference to
appropriate OASIS / TM specs (Bernard can you help me out here?)

(2) skos:subjectIndicatorRef is an owl:InverseFunctionalProperty. 

The reason for supporting (2) is that it allows description of concept
schemes via their indicators (i.e. without URIs) so you can have e.g. ...

<skos:Concept>
  <skos:prefLabel>Fruit</skos:prefLabel>
  <skos:subjectIndicatorRef rdf:resource="http://foo.com/Fruit.html"/>
  <skos:narrower rdf:parseType="Resource">
    <skos:subjectIndicatorRef rdf:resource="http://foo.com/Bananas.html"/>
  </skos:narrower> 
  <skos:related rdf:parseType="Resource">
    <skos:subjectIndicatorRef
rdf:resource="http://foo.com/Vegetables.html"/>
  </skos:related> 
</skos:Concept>

That's all.

Al.
