Er, that's not actually the case. If you can identify (/name)
something you can say things about it. Indeed by saying things about
it you can often determine what is being identified.
e.g. I create an identifier for something:
I can then say stuff about the thing identified (Turtle syntax,
omitting namespace decl.):
tag:pragmatron.org,2005:xyz pet:likes "dark places" .
( i.e. whatever it is likes dark places)
Already useful, SPARQL query:
?x pet:likes "dark places" .
(i.e. what in the world likes dark places?)
result, the statement above.
But as yet you don't know much about what's being identified. Here's a bit more:
tag:pragmatron.org,2005:xyz foaf:name "Eric" .
tag:pragmatron.org,2005:xyz pet:species pet:Hedgehog .
tag:pragmatron.org,2005:xyz pet:fedBy _:person .
_person foaf:name "Danny Ayers".
