´╗┐Another option is to use a quoting mechanism.

ex:BracketedTerm a rdfs:Class .
ex:termInBrackets a rdf:Property ;
  rdfs:domain ex:BracketedTerm .

The notions of "lifecycle", "state", and such are illusory.  What
changes are people's minds, not the URI.  The state is properly
predicated of some individual or collective consciousness, for example:

ex:AnApprover ex:approves [a ex:BracketedTerm;
  ex:termInBrackets   "http://xx/Berlin"^^xs:anyURI;
rdfs:comment "URI representing the city of Berlin." ] .
