I don't understand how this issue went away. Consider this
document:

<rdf:RDF xmlns:rdf="http:..." xmlns:ex="http://example/vocab#">
 <rdf:Description about="http://example/stuff#something">
   <ex:title>10</ex:title>
   <ex:age>10</ex:age>
   <ex:color>blue</ex:color>
   <ex:mood>blue</ex:mood>
   <ex:prop1>100</ex:prop1>
   <ex:prop2>100</ex:prop2>
   <ex:prop3>100</ex:prop3>
   <!-- ... and so on, up to ...-->
   <ex:prop10000>100</ex:prop10000>
 </rdf:Description>
</rdf:RDF>

Assuming S,
I can read that into an RDF store that only has one
object/pointer/cell for "10", one for "blue", and
one for "100". Then I can answer queries like those
found in most popular RDF APIs:

	statementsMatching(wildcard, wildcard, "100")

But if we adopt TDL, how can I do this without
allocateing 10000 cells? There
are interpretations in which each occurence of "abc"
denotes a different value/resource/object, no?

Maybe there's a straightforward answer that I just
don't see. Help?
