[Metadatalibrarians] Simple Dublin Core element for journal volume and issue number?

[Diane I. Hillmann]

Chris:

I'm sorry (but not surprised) that you're confused about DC.  I hope I 
can be of help.

Jenn is correct about the cite for official documentation.  You might 
also want to look at "Using Dublin Core" which has a whole section on 
the qualifiers: 
http://dublincore.org/documents/usageguide/qualifiers.shtml including a 
table which shows the relationships between terms.

The qualifiers are either extensions (or refinements) to the original 15 
elements providing more granularity, or some additional terms that can 
be used with DC.  The "original 15" live in two namespaces: in the 
legacy namespace they do not include domain or range restrictions, in 
the dcterms namespace they do.  You can use either, but probably the 
legacy namespace would work best for you.  There is an explanation in 
the introduction to http://dublincore.org/documents/dcmi-terms/ about 
the two namespaces.

Okay, but keep in mind that it would be hard for anyone else to use this 
data because what you're intending largely fails to provide any 
interoperability (which is why you're using DC in the first place, 
no?).  I generally discourage people from doing this sort of thing--even 
though I understand completely the desire to do something quick and 
focused.  That said, my original suggestions still apply.  DC simple is 
not capable of handling article data very well all by itself, and you 
have only a few tradeoffs available to you that would still pass the 
smell test.

If you look at the definitions for these elements ("Using Dublin Core" 
has some examples if you find the definitions not enough) you'll see 
that they are not suitable for what you're trying to do.  You'd be 
better off declaring your own term than squeezing things into DC 
elements where they don't belong.

Sorry to be so hard-nosed about this--I've been on the receiving end of 
some pretty squirrelly data in my time and tend to get cranky about 
funky uses of standard schemas.
