Well, I agree that is a problem, but don't draw the conclusion that there is something wrong with sameAs, just because people keep using it wrong. I guess your analogy to GOTO put my back up a little.

Well, I'm not (yet) sure what "entity provenance" means, but the main point is that if you have some information about A, and A owl:sameAs B, then that information is also about B (because A and B are the same thing.) I was assuming that provenance was not about the object, but if it is, then sameAs should apply to it in the same way as it does to any other assertion.

But OK, I will have to go read your stuff before commenting further, and that might take a few days.
