I can be a little bit of help here but not a whole lot.

Yes, I have written an SRU interface in Perl, and the source code is
here:

   http://dewey.library.nd.edu/morgan/sru/search.txt

It is a rudimentary interface. Functional but not robust nor modular.
It does not contain a CQL parser per say. Rather, the server looks at
the incoming requests, tries to execute it against the underlying
indexer (swish-e), if successful then returns results, if not, return
zero records.

On the other hand, Ed Summers, who is participating in the NSF OCKHAM
Project, is in the beginnings of writing an SRU client/server module in
Perl. Included in this work will be some sort of CQL parser, again,
written in Perl. Ed, will you please elaborate on the work you've done
to date and what you will be doing in Phase II?
