In this light I see a difference between DCAP and DCX. A schema maybe
part of DCAP when that schema contains one or more DC terms. Am I right?
In DCX I meant all DC and DCTERMS terms to be part of this DCX schema
automatically by default.

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
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 (,
to be discussed in a separate posting) say: "By definition,
a DCAP is based in part on Dublin Core and follows DCMI
Grammatical Principles ."
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
