These points make my head ache a little. But I can immediately see the
importance from my own pesrpective as someone with a large (and
growing) collection of documents. There is more than an academic
interest here in this office.
Each document is part of the general collection called
Education-line. Some of them are subsequent versions of, or
comments on other documents. Some are parts of subsets - papers from
a given Conference for example. The HTML texts are nearly all
derived from word processed versions that can also be retrieved from
the collection.
We have started to put DC tags onto the head of each document. We
have made some basic errors that need sorting, but I am begining to
see how the DC protocols will eventually be a fairly painless part
of what we do during our indexing process. If anyone wants to take
a closer look, retrieve one or two of our most recent additions
(there is a search button dedicted to this very thing) from
http://www.leeds.ac.uk/educol/BEID.html and you will have
something to try to stick real mud on (as it were)
Best wishes
