from & until: Illegal dates (I agree)
identifier: what's an illegal uri?
a) one which dosn't match oai:[a-z]+:.* (regexp may be slightly off)
b) one which dosn't match oai:nameofarchive:.*
I suggest (a) - it's possible that an archive could mirror OAI records
from another archive AS WELL as it's own. (Isn't it?)
resumptionToken: If an archive dosn't support this
then I suppose it should always give a 400 error.
Isn't there an 'expired' return code in http? it's confusing giving
the same response for 'illegal' and 'expired'
set: not matching [a-zA-Z0-9_])+(:[A-Za-z0-9]+)* is a 400 error but
how about a set which passes the spec but isn't in the archive?
I suggest it just returns a header with no results in that case.
metadataPrefix: similar. Not matching [a-zA-Z0-9_]+ is illegal (400)
but what happens if it passes the regexp but isn't in the list
supported the archive?
Again, I suggest it just returns a header with no results in this case.
oai_dc: When should we put a 'oai_' before the metadataPrefix,
exactly what does it mean (why isn't it just dc?)
inside <metadata></metadata> is ANYTHING defined by OAI or
is everything, including the initial tags <dc></dc> and namespace
etc. defined by the metadata standard?
