Right, I was questioning the use of Axis for SRU, not for SRW - sorry
I didn't make that clear.

Well you certainly don't for the SRU implementation, but for SRW I'd
just say that (in all the SRW implementations i've done so far) it's a
case of the right tool for the right job. Of course we can hand craft
the codecs and parse/produce the XML by hand. However, the SRU/SRW
community comes from a background of interoperability as a sacrosanct
requirement. Given that background, having something parse wsdl and
produce your codecs for you gives people (me) a warm fuzzy feeling
when
it comes to WSI compliance. It also makes the release process much
easier when it comes to upgrading the protocol version: Just pop a new
wsdl in the build tree and compile. Of course there are other reasons
too, but thats a starter for 10 :)
Solr has some pluggable capability, detailed here:
Ah ok thanks for that. I've taken a quick look and I'm trying to
figure
out how we might be able too expose extra features, like the
ability to
request results be returned in different schemas. I'll keep at it tho
and check back if I have any questions.
Cheers,
Ian.

Hiya all...
I'm interested in the possibility of contributing SRW/SRU web
services
interface/module to solr (see http://www.loc.gov/standards/sru/).
SRW/SRU is the web service definition which is often used along-
side or
instead-of the more traditional Z39.50 protocol for cross/meta
searching. a solr SRW/SRU interface would enable meta-search
engines to
transparently include solr repository search results by only
configuring
the base URL of the service. I've already got the much code to do
much
of whats needed (IE, CQL to Lucene query rewriters and code to
generate
the right stubs using axis etc). Actually, I might be up for
creating a
z3950 module too if anyone is interested?
Why do you need Axis for this?
So my first question really would be... Is anyone out there already
working on such a beast? If so, do you need any help? Seems
pointless to
create a second add-on. I've searched the lists (Not in any great
depth
tho) and can't see any references to SRW/Z3959. Assuming nobody is,
I've
got some follow-up questions about the best way to package up what
might
be add-on modules.. is this list the right place to ask?

You can simply create your code, which I presume would entail a
SolrRequestHandler and a QueryResponseWriter, and distribute it as a
JAR that others could just drop in and run with it.
