Re: Issues with XML and Semantic Web ?

problems with rdf

As I cannot get to the challenge :), I will talk about the pre-challenge 

I think syntax is only 1 of the problems with RDF - but definitely a 
problem. RPV makes syntax better, but not sure if it works..

Other problems with RDF as mentioned --
1. Even if I know the "predicate", I have to look up and find out the 
2. for RPV, where R and V are both URIs, there is a confusion between 
whether we should write RPV or VPR -- this will be a problem, probably the 
predicate explanation will have to include this, with examples..

Who can benefit from inferencing supported? - I believe domains where 
people do not mind doing this bit of extra work, provided they get lot of 
benefit. I think data (and not metadata) describing symptoms of diseases, 
and symptoms of symptoms etc in the medical domain from different parts of 
the world/different hospitals etc??

best, murali.

Note; In RDF Schema, I am curious why subproperties do not talk anything 
about domain and range being subclasses.. To ensure that the logic stays 
in first-order? I am not sure if this will affect a lot, when do we need 
subproperties/subclasses in the first place?? Not in the application 
domains that I am thinking of??
