The Linked Data 'movement' started, as I recall, in the use of http: URIs as the convention for all RDF resources.... FWIW: IMHO, the biggest impediment to linked data standardization is not the link, or the data, it's the perception of redundancy for authors in one Document Object Model or another. The owl:sameAs is not the same logical assertion as owl:equivalentClass. Take for example a data base and a HTML page. Both presumably have some sort of URI, which points to the root of the DOM at a fixed point (not the "title"). You can give a database a "title", so that's ok. But you have to understand that the data base is all /html/body or to put it another way, that /html/head/@profile defaults to <ANY>|(null). What you really want the profile to default to is <RDF:rdf> or some rdfs:subClassOf (Dublin Code, SKOS, OWL, FOAF etc.). Only then will the meta data be "exposed" (as opposed to "printed") properly. In the same way as you added a "title" to a data base you could add a fixed "profile" + rows of elements (Collection). For linked data to "work", either a retrofit of data bases (with title and profile) or a retrofit of HTML (either profile or /html/head/meta/@xlink:type="locatorLink") is necessary.
