Hi all, Apologies for the cross-posting from our own announce-lists, but for anyone who feels like playing with the SRW protocol, we thought this might be interesting. Apart from a slew of updates and fixes, the most interesting aspect of this release is probably that it includes support for the core parts of the SRW protocol in the client and server roles. In a nutshell, the high-level ZOOM client-API now allows you to execute parallel operations against a mix of Z39.50 (v1, v2) and SRW 1.0 servers. This functionality should eventually percolate into those those other ZOOM implementations that are based on YAZ/ZOOM. Why use a dedicated toolkit to implement SRW as opposed to a standard SOAP tool? First, our early experiments with SRW have shown us that many of the current generation of SOAP toolkits are somewhat less than fully reliable, and some are platform-specific (our SOAP implementation uses libXML). Also, many of them are designed for conventional remote procedure-call interactions -- not parallel searching and retrieval operations which is where we think the real fun of Z39.50 begins. Finally, 'hiding' the SRW protocol under the abstraction of the ZOOM API makes it close to trivial to implement clients that can communicate seamlessly and concurrently with SRW and Z39.50 targets. On the server side, the generic front-end server now also supports SRW -- allowing you to support both protocols in a single server with a limited effort. The software page, and full changelog, is available from http://www.indexdata.com/yaz/.
