Not all Vocabulary Terms Available

I’d like to use the dcterms:location term, but it’s not available when I try to add it to a template. I tried adding the dcterms vocabulary, but got an error message saying it was locked. Is there a way to make this term available? I’m trying to create a field to list the place of publication of a book or other similar item, so if there’s a better term to use instead, I’d be happy for that info too.

dcterms:Location is a class not a property, so it can’t be added as a template term. The vCard ontology has several data properties that describe an address, including vcard:street-address, vcard:locality, and vcard:postal-code. You could import the vcard vocabulary and add those to your template.
