Hi,
Some naive thoughts on tagging for audience etc:
I agree with Prue Deacon, if the prime aim is to provide good searching,
then putting things like audience in 'description' isn't going to work. I
suspect there can be no really good solution in DC, because of its
commitment to 'context-independence' Try this for a partial proof:
Natural languages have the W-adverbs, Who, Where, When, What, How, How
Much, Why.
DC handles Who/Where/When/What (=subject)/How (=Format)/How Much (maybe?)
but not Why. (Except possibly in a wimpish way with Type?).
What is needed for effective retrieval is often the reason/purpose for the
resource.(e.g. the examples quoted by Prue, Liddy Nevile, Frederic
Wronecki). This reason often sits within a process, i.e. cannot be
context-free.
It seems to me that people often try to force-fit context information into
subject and keyword fields and this just does not work.
As a DC novice, I would hesitate to mention the possibility of an element
known as 'purpose', but would be interested to hear from the experts whether
such a thing had been mooted and then dismissed (and why).
