[oslc-core] Update to oslc:Publisher and its description for dcterms:identifier

[Steve K Speicher]

As previously discussed at [1], I recommend that we change the language of 
[2] to be:
        "An unambiguous reference to the resource within a given context." 
  (which is word for word what DC has).
from:
        "A URN that uniquely identifies the implementation "

Any issues with me making this change?
