[OAI-implementers] Is this a valid OAI-PMH response?

[Michael Nelson]

Stuart,

Here's the short version: you're correct and your vendor is wrong.  The 
inner <record> in the example below should be <oai_dc:dc> as you correctly 
surmised in your email.

Regardless of what the validators say, tell them a quick inspection of:

http://www.openarchives.org/OAI/openarchivesprotocol.html#Record
http://www.openarchives.org/OAI/openarchivesprotocol.html#ListRecords

should make the intent clear.

regards,

Michael
