So u denotes the resource which matches p and also u names the graph which describes p? Is that a good thing? ( O/T & AIUI, at the moment Earth only has one known natural moon but for a while until last September it had two, though the second was quite small: http://www.birtwhistle.org/Gallery6R10DB9.htm If you want to read that it might help to know that NEO = near Earth object and LD = lunar distance. It's also a nice example of naming: 6R10DB9 was the temporary identifier given to the object by the discoverers, 2006 RH₁₂₀ is the temporary designation given by the minor planet center for the object. If it's seen enough times (over the years) to have a firmly established orbit it'll be given another designation. There are lots of cases where objects are given multiple temporary designations until their orbits are linked and the designations are merged. It's very tempting to use owl:sameAs. :-) )
