Tom,
This makes sense I think, but I still feel that I need further
clarification.
Assume that I've defined 2 new properties:
- my:price (which has no relationship to existing DCMI properties)
- my:duration (which is a refinement of dcterms:extent)
I create three metadata records containing *only* the following
statements, as follows:
Record 1
--------
<my:price>$25</my:price>
Record 2
--------
<my:price>$25</my:price>
<my:duration>25 seconds</my:duration>
Record 3
--------
<my:price>$25</my:price>
<my:duration>25 seconds</my:duration>
<dcterms:dateSubmitted>2003-09-16</dcterms:dateSubmitted>
For the sake of argument, assume that all three examples conform to 'DCMI
grammatical principles'.
In my view, none of these *is* a 'qualified DC' record. Record 3 can be
said to 'incorporate qualified DC'. Record 2 dumbs-down to a 'qualified
DC' record, but is not itself a qualified DC record.
Do you agree?
I further create three very simple application profiles that define 3
applications limited to the properties used in the 3 records above.
(Yes, this is all very hypothetical!).
I'm unclear which of these three you would say conforms to a DCAP. Only
3? Both 2 and 3? All of them?
