Statistics on the use of IAFA templates in the ROADS and other UK services
are available at
http://www.ukoln.ac.uk/metadata/templates.html
The top five attributes used (other than URI) are:
Description, Title, Keywords, Subject Descriptor, Subject Scheme
I would agree with the recent mails regarding the importance of the
Description in implemented services. Its a field which seems to be used in
most automated webcrawler index records (first twenty words or whatever)
as well as in manually created records. The description is a free text
narrative so differs in an essential way from fields containing 'subject
terms'.
In our statistics, the next most popular attributes for document like
objects are:
Author, Copyright owner, Admin-email and Publisher
So Dublin Core would collapse our nine most used elements down to five (or
four if Publisher is combined with OtherAgent). Four of the IAFA fields
would be mapped to the one Subject DC element. It does seem Subject would
be carrying a lot of information which would need to be differentiated by
the scheme device.
