[OAI-implementers] Reconsidering mandatory DC in OAI-PMH

I agree with Tom. The breadth of records in OAIster is due in large 
part to the use of the DC format by data repositories. While it may not 
be too difficult to create new XSLT stylesheets to parse non-DC 
formats, it does take time and effort (essentially money), which is in 
short supply. I recognize the need for different uses of OAI-PMH, 
however, I think we need to continue to support its use for large-scale 
service providers. I would vote for less stringent measures regarding 
the DC format.
