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:

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. :-) )
