Dear w3 members

I work for PharmaSoft, a firm that develops applications for the
medical sector. We are currently developing a
new information system that should include precise information about
drugs. RDF with its structured metadata 
is therefore an interesting approach to consider. Concerning PICS, I
read the following on your site
http://www.w3.org/TR/WD-rdf-schema/:


>The vocabulary that appears in a PICS-1.1 label is a mixture of
descriptions of the service providing the rating, >data having to do
with the mechanics of transporting the ratings, descriptions of the
ratings themselves, and >descriptions of the target resource. The
vocabulary associated with the transport mechanics (error, for) are
not >included here. The generic keyword is handled by the RDF
aboutURIPrefix mechanism. Two deprecated >PICS-1.1 options
(signature-RSA-MD5 and MIC-MD5) are omitted from this vocabulary. 

Security techniques seem to be left behind.
Since reliability on medical information is paramount, we must have
some means  to ensure that the information
found on a site is valid. I have only found vague thoughts about
digital signatures (DS) in your documens, but
nothing concrete. Are you planning to include DSig1.0 or the med-PICS
system into RDF? Or are you
planning something different? Are there specs on the Web I have missed?

Your information would help me very much to choose the right approach
to my task.

Best regards,

A. Deller
