I don't see any instances of people in /TopBraid/Common/foaf.owl. Perhaps the file that you imported it into had a few and they didn't show up until you had the FOAF ontology in your Classes tree so that the people were easier to find?

It's interesting where this discussion has taken off. Indeed, I felt that the XSL style sheet for this kind of thing was messy. I was looking at one that was done with foaf-visualizer.org - that's the web address of the application. The XSL tries to handle at least 4 or more large ontologies, maybe even more than that. I'll have to look at the guides you mention for creating applications using TBC Maestro Edition and TopBraid Live. Bruce P.S. I noticed something curious... When I import foaf, the version that comes with TBC are there a few names in there that get imported as available instances? I don't think they showed up in exports or my working file but I do see them as instances and I had been very confused at first as to where those names came from...
