Hi Code4Libbers, I posted this on the Web4Lib list mistakenly last week, and apologize for any cross post. I am just curious to know whether there are any open source NCIP APIs out there. I have noticed that IndexData are doing something with NCIP: http://ncip.indexdata.dk/ "In addition, Index Data has tools to allow the integration of external functionality using the NISO NCIP protocol, if relevant." (taken from: http://www.indexdata.dk/keystone/retriever/ ) I did get a reply on the list from Joshua Ferraro of LibLime, who said that they began development on an open source SIP2 API, which was to be extended to NCIP functionality. This extension to NCIP did not happen. This SIP2 api is now in use in the EvergreenILS and soon to be used in the Koha ILS. See: http://openncip.org http://sourceforge.net/projects/openncip I suspect that there are probably no other attempts out there, but if anyone has any .
