[OAI-implementers] Open Archives Initiative Protocol for Metadata Harvesting Version 2 news

OK. This all sounds sensible. Maybe openarchives.org could have the
"bare minimum howto" which tells you how to neatly do the bare minimum to
support the protocol. 

The next version sounds like it will be more complex, but that complexity
will be optional. 

We should make it clear to people "checking it out" that it's easy to meet
the minimum requirements.

Is there a plan to add some more characters to the setSpec regexp? Preferably
everything other than ":" or near enough.

thanks, Chris G / eprints.
