Dear all, the point here is that this "philosophical" discussion is exactly the reason why Semantic Web/Linked Data is not really popular amongst developers. I am involved in the Semantic Web Community since 2001 and even I find it complex and impractical when it comes to really realising applications.
When I request a Linked Data resource, I expect what comes back to describe what I requested. Otherwise, I as a developer have no way of knowing how I should access the data: when I request a resource that is a document and I get back a description of a person (i.e. other subject) how should I know where to start? Just to give you another example: when I request the resource http://www.w3.org/2000/01/rdf-schema#label, the request to http://www.w3.org/2000/01/rdf-schema (without the #label, since this has to be removed by the browser) will return me the whole schema document. If I want to know about the requested rdfs:label, I will have to filter out the triples that are relevant. Now how would I know this in the case above? The Semantic Web needs more developers, not more philosophical discussions. Developers need well-defined behaviour, and not "this service does it like this, and that service does it like that". This is not the interoperability promise the Semantic Web gives.
