But that's ok. All I want is that the results "-79" and -79 are merged by the
UNION statement and this is accomplished using FILTER.
Thanks Roberto!
Now the my last issue is the unit of the meltingPoint property/ontology.
If anybody knows if there is a convention about it, please tell me.
And if you know that there is no such convention and one cannot rely on this
information, please tell me as well.
Cheers,
Manuel
