Koha is a web-based ILS, with a SQL database (MariaDB or MySQL preferred[citation needed]) back end with cataloguing data stored in MARC and accessible via Z39.50 or SRU.

[5] In 2001, Paul Poulain (of Marseille, France) began adding many new features to Koha, most significantly support for multiple languages.

Support for the cataloguing and search standards MARC and Z39.50 was added in 2002 and later sponsored by the Athens County Public Libraries.

Fifty-seven libraries have chosen to adopt Koha and moved to the shared production environment hosted and supported by ByWater Solutions.

[12] In 2011 the Spanish Ministry of Culture began maintenance of KOBLI, a tailored version of Koha[13] based on an earlier report.

The dispute centred on LibLime's apparent reluctance to be inclusive with the content of the sites[21] and the non-contribution of software patches back to the community.

[30] The Koha community and Catalyst IT Ltd (NZ) successfully appealed against the provisional trademark grant, with a decision handed down in December 2013[31] and with LibLime to pay costs.
