 I need help from folks who understand query semantics (and ideally secure query semantics). I could pull the graph from the webid in the cert, and follow redirects., bob.example is redirected to bob.xxx. Ive no idea if the identity of the graph in the local repository is titled with the webid, or the fourth redirect the webget library I've used just followed. When  I issue the above query, with the webid from the cert(bob.example)  against the local triple store (sourced to bob.xxx), will it match my graph? Assume my graph has no cert.identity (deprecated) and no foaf.name property. Now, as I recall there was a variant, in which there was the likes of SELECT FROM <uri> (and presumably there is an ASK FROM <uri>.)  Does it make any difference whether I webget a graph (following redirects) or use FROM?  Can I assume that the handling of redirects and any fixups in the query as presented is specified in the query language design, when one uses the FROM option? Which is more "appropirate" for the state of the web, today?
