   Hello,

   You can find the presentation that I did during
Registry session 5 on the meeting page:
http://www.ivoa.net/twiki/bin/view/IVOA/InterOpMay2006ResReg
   Especially, on the last slide, I tried to identify
the metadata tags from the Registry ResourceMetadata
document that could correspond to the main categories
that you identified. Comments are welcome.

   By the way, I'm a bit uncomfortable with the usage
of the UCD term in your mail. For example, I totally agree
that we need a UCD meaning "algorithm". But the different
possible values described by this UCD are not UCDs. They
can be words in a normalized vocabulary, you can write
them using a "a la UCD" syntax, but they really are not
UCDs.
   To tell it in a few words, we can have a UCD for each
ResourceMetadata element. The UCD is used to give a name
to the empty box, and this name is not specific to a given
schema, unlike the name of the XML element.
   The values you put in the box can be issued from a
normalized vocabulary, but they are not UCDs in the original
sense.

Sebastien.
