Quite right. If I am to use your same-ness (and seeAlso-ness, differentFrom-ness etc) knowledge, I need to know quite a lot. For a start: What aspect were you concerned with (eg for geonames is it administrative or geographical)? What were your heuristics (eg conservative or liberal)? How much do I trust you (if you also own one of the URIs, that is a good indication, as with Tim's foaf)? How much are you charging (I can go somewhere else cheaper, or pay more for better)? Of course, these are complex things to represent, as we know. But knowledge of them will allow me to see how they match against my requirements for the particular SW context I am in. Sometimes I want one Tim and other times I want two Tims. These needs don't just apply to same-ness, but seem to be particularly important for it. This is because it is a strong statement that bridges knowledge sources. If I get it wrong (for my context), then it has the ability to spread out and pollute widely. Getting the geonames wrong would have bizarre consequences in working out whether resources were close to each other.
