   Re: [xml-dev] RDDL possibilities

[ Lists Home | Date Index | Thread Index ]

Both of these are interesting directions to take RDDL in.

This is very interesting - would these resources be clustered around 
something (the name-space as an abstract concept, for example).
IMHO, this is eminently do-able with Topic Maps...

Equally do-able with topic maps.

I would just be interested to hear if RDDL developers considered and 
discarded the possibility of creating a set of Published Subject Indicators 
for a topic map-based solution (with the associated semantics) and if so, 
why ? One potential advantage in this approach is that later changes would 
not require additional syntax - just new PSIs and more semantics.
