Folks,
        Just seen some info on slashdot about the
Open Archive Iniative http://www.openarchives.org/
this seems to be a common standard for "harvesting"
metadata (i.e. info about the document: the creator
 of the document).

I think theres a strong case for working with emerging
standards as it will make our stuff more interoperable
with other archives.

An example doc follows. I've added a few comments
to explain thins a bit maekerd by ---- ar start of line

<header>
    <identifier>oai:arXiv.org:cs/0112017</identifier>
---- Url of doc this is metadata for.

    <datestamp>2002-02-28</datestamp>
----- Date of creation

    <setSpec>cs</setSpec>
    <setSpec>math</setSpec>
----- defines subject area

        a long established format for metadata.
        Boring but necessary for correct xml.

   <dc:description>With the increasing technical sophistication of both
    information consumers and providers, there is increasing demand for
    more meaningful experiences of digital information. We present a
    framework that separates digital object experience, or rendering,
    from digital object storage and manipulation, so the
    rendering can be tailored to particular communities of users.
