Unapi
unAPI is a tiny HTTP API for the few basic operations necessary to copy discrete, identified content from any kind of web application. See http://unapi.info/ and http://en.wikipedia.org/wiki/UnAPI for more Information.
For integrated library systems ist is often necessary to process bibliographic records, and unapi is a way to get those records out of the system.
* Koha 3 comes with an unapi implementation * For OCLC/PICA LBS systems, an implementation is available from ftp://ftp.ub.uni-marburg.de/pub/research/unapi.tar.gz
