apols for late reply
I just saw this email, not sure why but some I seem to miss some mails
OK, let me take a stab at some answers below

well, Denise already answered part of your question (what format is
the taxonomy)
what formats need to be supported, is for us to decide

here is the bottom line idea: use the taxonomies to populate drop down
menus to model
'expertise' . I am working on a 'model of expertise', see the demo
posted on foafx group
(foafx.punfai.com)
That's just a foaf based example of person schema that represents
expertise(albeit rather notionally at the moment). The idea is that we
put the taxonomies at the back of that, so that people can select
their expertise from a structured taxonomy.

I have heard that there is an updated version coming out, in principle
afaik there is no limit to how large a taxonomy drupal can support.
The important thing would be the management function, which may have
to be upgraded or customize to suit our purpose. I hope it can do the
job, maybe by working with the module developers, or that we can find
someone to ramp it up. The benefit of Drupal, if we make it work, is
that it comes with an integrated front end that means it should be
easy for editors and users to work with it, but I have not yet matched
the reqirement with the functionality fully, still exploring
alternatives?

cause I need users to select items from it that would populate their
expert profile

in drupal you can simply add terms to any vocabulary, we would have to

i am thinking of terms that represent knowledge domains, I dont think
we would encounter the same problem that you describe above there. I
am thinking of merging 'lists of knowledge domains', the purpose, the
way I figure it, is to show that for example history of arts, can
belong both to the history and to the arts domain, therefore it should
belong to both
do you see a problem with that?

I think it can be used as a reference, like a thesaurus, and to
tag/organize person data or other content, for users who register on
the site. I am sure more applications would develop from there

that, and the other taxonomies/vocabularies that we may be able to gather
for example, I am collecting vocabularies in the field 'emergency
mangement' , I would like to be able to map them to one another using
this system
does it sound far out?
let me know what you think

following my mail below,I forgot to mention that it may be necessary
to prune (albeit temporarily) Denises concept set for
practical/implementation purposes

thanks for late reply, and sorry for double late reply
I seem not be able to see your new messages in the inbox, and only now
by chance found it as I was looking through old correspondence
I have met Denise when in DC, and we are talking about things - the
only progress to date is with the foafx prototype, which represents
one part of the project, more to come
Btw I also met Ravi, but we did not speak about this particular
project as we had other business in hand ...
SKOS is a possibility, but I prefer NL, nothing prevents us from
having the K expressed with different representations
I will keep everyone posted as things develop, please do the same if
you have any sense of direction.
speak soon
