Currently these are inadequately documented, and there is already some variation and ambiguity in the few testbed data files we already have. The guidelines describe how to reference your RDFWebRing page from your normal homepage, and some other mechanisms for announcing its existence to the Web. Various RDFWeb tools watch the Web for new files, and combine your data into a database along with many other similar files. This provides an organising principle for blending together data from different sources. We can't always tell when two people are talking about the same thing, but we can try.
Personal mailboxes are a good example.
So RDFWeb can use this kind of fact to integrate data. Note that we don't have stable IDs for the people, so RDFWeb software will have to do a bit of extra work to integrate and normalise this data when it merges it with factoids from the RDF home pages of the other people mentioned in the graph. We can achieve this through knowing that for any specific value of some uniquely identifying property, there can be at most one Web-identifiable resource with that property value. This trick works for people and email addresses, organisations and their home pages, restaurants and their telephone numbers and so on. This document was written by dan brickley and libby miller with lots of ideas and suggestions from members of the rdfweb-dev mailing list.
