This is the sort of think I don't think we need to wait for
Authorities to "give" us. Where we have uniform headings
strings we can just define a hash function to give us
stable identifiers, e.g. sha1("World War, 1939-1945").

Nothing stopping us from putting them in a namespace,
e.g. http://purl.org/net/lcsh#<sha1> that returns,

@prefix lcsh <http://purl.org/net/lcsh#>.

lcsh:672369b2e70511c1455c53e00fecac622f4fc21b
    dcam:member dc:LCSH ;
    rdf:value "World War, 1939-1945" .

It would be trivial to generate some inference rules as well,

{ ?x dcam:member dc:LCSH .
   ?x rdf:value "World War, 1939-1945 } =>
{ ?x owl:sameAs lcsh:672369b2e70511c1455c53e00fecac622f4fc21b }.

That could be used for normalising "old style" dc references
where the dc:subject is a bnode.

The point is, we can do this now and don't need to wait on the
Library of Congress to do it. If they eventually do mint identifiers,
we can just put another owl:sameAs in.

Just my £0.02
