Dear Kerin,

Thanks for your answer about skos:notation, I crossed the same need at the
Publications Office of the European Union and I prefer your solution as the
one I was thinking of (create sub-properties of skos:notation).

You might have an answer to this related question:

The same concept (same URI) is used in a thesaurus and then reused in an
other conceptScheme representing a taxonomy. In each conceptScheme we want
to give an id to the concept related to its location in the conceptScheme
hierarchy, something like 4.53 in the first conceptScheme and 2.4.55 in the
second. We use skos:notation for this property.

We need to say that one skos:notation is valid for the first conceptScheme
and the second one for the second conceptScheme.

Would you use the "rdf:datatype" solution to differentiate the 2
skos:notation and relate them to the proper conceptScheme ? Would you use
an other solution ?

The reuse of concept (using a single URI, not skos:match) in several
conceptScheme brings a lot of questions, but this is one for which I don't
have any good answer today.
