We had this discussion among the Linked Science workshop organizers several times. I'm with Paul, I think that a human-readable description is central to the dissemination of research results (and will probably remain for the foreseeable future). I'm not saying that PDF is the best way to do this,

Dear LODers, I have already bugged this list with our Humanitarian eXchange Language project a couple times, and I'd like to hear your opinion on the following problem. We are constantly working on the vocabulary (see http://hxl.humanitarianresponse.info/ for the latest version), so it gets

Dear Kingsley, But this is what (most?) triple stores do with the default graph in the absence of FROM/NAMED clauses in queries anyway. (Certainly this is the Sesame approach, followed by OWLIM.) Not so re. Virtuoso. The Graph IRIs don't matter. Only used them if you explicitly seek to

Hi Bob, At a first glance, your ontology looks very interesting and well designed. thanks, we are doing our best ;) So there might be the (rather old) need for statement identifiers, i.e., a URI (or maybe also a bnode) for identifying a  single triple and to be able to describe external

Hi Gannon, I agree with the comments below.  I think what Bob is suggesting is that you include a non-ontology Core (DCMI for example). I am not sure whether I get that correctly, but it is pretty clear to use that we need something like this. We are already using some of the DCMI properties
