Index Data has released version 1.01 of their SimpleServer toolkit for implementing information retrieval servers in Perl, now with support for SRW/SRU.

The built-in CQL parser makes it possible to write a single set of 'glue' routines for your backend database, and have instant support for both Z39.50, SRW, and SRU. Existing SimpleServer-based servers can implement SRW/SRU simply by upgrading to the latest version of the software and adding configuration to determine the mapping of the CQL query language.

Documentation and code is available from Index Data or CPAN.
