Tom, the definitions of Thema and Nomen are:

Thema: any entity used as a subject of a work
Nomen: any sign or sequence of signs (alphanumeric characters,
symbols, sound, etc.) by
which a thema is known, referred to or addressed as.

I read this to mean that Thema = concept, but I'm less sure about
Nomen because it appears that the term Nomen covers both identifier
and a prefLabel (see section 6.2 where it gives the attributes of
Nomen as "identifier" and "controlled name").

MZ: I may have lost tracking the discussions today.  I just want to
mention one thing I discussed before in my previous email, the
frsad:Nomen type 'identifier' is one example of a type of nomen.
It could be a common kind of identifier we have
seen, such as the Chemical Registry Number of any chemical
compound.  However this is not to be mixed with an 'identifier'
that represent a thema's location or placeholder in a database or
Any implmentation.  I would compare this with the situation of
skos:Concept.  Each skos:Concept is usually represented by an
identifier (including URI), but this identifier is not a part of
a conceptual model, i.e., it is not modeled as a property
of a skos:Concept in the SKOS reference.
One reason to provide examples of these values for a nomen type is that we were asked by some reviewers to
map FRSAD to FRAD which had been released just before our draft report was released for review.
The relationship of FRSAD with FRAD is explained in FRSAD appendix B while some statements
were also included in the main body of the report.
I hope this clears the question you had in your message.
I will catch up with other discussion issues later.
