If TopBraid recognizes a graph's URI as one within the current workspace (e.g. http://topbraid.org/examples/kennedys) it queries the local copy.
The simplest way to query local and remote data together is to create a new model and then import the relevant graphs into that model. In the online help, see TopBraid Composer > User Interface Overview > Imports View; note that the icon with a + over a picture of the world lets you specify remote files to import, so you can include both local and remote data in the model. (If you get a chance to attend our upcoming training in September or December, you'll see this in action many times. See http://www.topquadrant.com/training/training_overview.html for more information.) How much to include in each file: owl:sameAs is unnecessary here. If the two triples <http://some/path#person2> foaf:familyName "Smith" . <http://some/path#person2> foaf:givenName "Joe" . are in two different files are not, it doesn't matter as long as the query has access to all the relevant triples. The Imports View described above is the best way to group multiple files together for easy access to all of their data at once with a single query. As to your third question, yes, that's me!

Does Top Braid go out to the web and get the files to run these queries? I mean if you are running a query using the FROM clauses that specify URI addresses, does it try to go get them when you select execute query? Quite often during development, I know where I am going to put my files, the final URI, and URL, but I also have local versions of the files. For example, it is often the case that people will have foaf:Person resources for other people inside their own FOAF file. I'm not sure if there is any benefit to that. I was doing some modeling for a Genealogy project and was thinking, "well, I could specify the information about person2 inside person1's file and use an owl:sameAs to say there is more information in this other file about person2" or I could just say person1 bio:mother <http://uri/for/ mother>. Some say redundancy is ok but the decision gets down to how much should one include in any one file, especially if every possible query that one might want to do later is not known. Any thoughts? I guess it is somewhat of a subjective issue. Thanks, Bruce P.S. I'll have to get that book on SPARQL that you wrote, Bob. I assume that you are the same person that wrote that book.
