Dear all,

I've been working on Celestial (my OAI cache/aggregator thingy), and have
made the next version live at:

This addresses a number of problems (and probably introduces a few new
- Splits data over multiple tables (to get around OS 4GB limit)
- Full set support
- Generates UIDs for repositories as "hostname.identifier" for 1.1, or the
repository part of 2.0 repositories
- Improved configuration
- Improved error messages

As you may appreciate its something of a kludge to get the set structure out
of 1.x repositories, so I would appreciate any feedback as to whether this
is working successfully/whether its overloading source repositories?

I've written a short script which exports the list of harvested

This is the same format as the OAI ListFriends.pl, but with an added
attribute "mirror" which is the BaseURL of the repository at Celestial.

Note: The repositories listed in Celestial are only those listed on the OAI
web site, which were working at the time of configuration.

All the best,
Tim Brody
