Re: Issues with XML and Semantic Web ?
As I cannot get to the challenge :), I will talk about the pre-challenge portion. 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 predicate. 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??
