HI Phil,

+1 from me - isn't this another way of doing packages, as we used to
call them?

Subject: PROPOSAL to allow multiple descriptor sets in DRs

I've been looking at the implications of allowing more than one
descriptor set (and tagset) within a DR and can't find a reason to limit
their cardinality to one - which is probably good.

The use case for this would be where one organisation is creating DRs
from different (knowledge) domains. To give a real world example, FOSI
is likely to be launching its own trustmark later this year,
independently of the usual ICRA stuff so we might well have a Web site
that needed, say, a different ICRA label for different sections but the
same FOSI trustmark across the whole site - hang on - er, that would
apply to our own site, so how's this (note the use of the ordered list):


     <descriptorset src="#someNudity" />
     <descriptorset src="#FOSItrustmark" />


     <descriptorset src="#noNudity" />
     <descriptorset src="#FOSItrustmark" />

To process either DR you'd fetch the two descriptor sets identified in
the src attributes and apply them all to whatever your candidate
resource was. So allowing multiple descriptor sets allows you to mix and
match them within a DR - something I recall talking to Dave/Segala about
in the past as being something that would be useful.

It works in POWDER-S too.

Each of those descriptor sets would create an OWL class with an nodeID
of descriptorset_x and the sub class relationship would be

<owl:Class rdf:about="#iriset_1">
   <rdfs:subClassOf rdf:resource="#descriptorset_1"/>
   <rdfs:subClassOf rdf:resource="#descriptorset_2"/> </owl:Class>

Look OK to everyone?
