Re: [Rails] OAI-PMH problem with more than one parameter.

Hi,

As you know the OAI-PMH standard is pretty specific about what are
acceptable parameters to requests and "test" is definitely not one. I
have a pretty customized version of the OAI lib running on the Kete
project and though it answers properly formed requests correctly it
gives a 500 error when passed "&test=test", too.

You seem to indicate that you have tried other second parameters, but
are they definitely valid. Here's a valid URL query string, for
example:

http://yoursite.com/oai?verb=ListRecords&from=2010-01-01

and here is one with a valid third parameter:

http://yoursite.com/oai?verb=ListRecords&from=2009-12-01&until=2010-01-01

You may get "no records match" type message, but it should be a well
formed XML response.

Hopefully it is just a matter of testing with valid parameters and
things will come right. At the least it is good to narrow down your
issue.

Cheers,
Walter
