The question "how many DC properties does it take to make it a 'DC' record" (if one could put it that way) seems like a red herring. In my opinion, the point is not so much which terms are used -- whether they are owned and maintained by DCMI or not -- but what underlying grammatical typology (e.g., elements versus encoding schemes) or Abstract Model is being used. The CEN Guidelines for Dublin Core Application Profiles ([1], to be discussed in a separate posting) say: "By definition, a DCAP is based in part on Dublin Core and follows DCMI Grammatical Principles [2]." I don't see how one could be more specific than "based in part" (we don't want to go down the path of deciding whether it takes at least 1, or 5, or 15...). In my opinion, the emphasis on the model is what is important here. The DCAP guidelines address (by analogy) the question of whether a record could contain zero properties and still be said to conform, as follows: "A DCAP consists of... one or more Term Usages." That seems like a sensible criterion. (By another analogy, one would not say that an English speaker sitting quietly and not uttering a single word was "speaking English".)
