LibLime Koha is the most mature of the open source ILS applications. Based on the ground-breaking 3.0 platform (derived from the original Koha offering of 1999), LibLime Koha is a completely web-based open source ILS, with library staff, systems librarians, and library users all accessing LibLime Koha through a web browser. Relying on the MySQL relational database, all LibLime Koha data is readily accessible.
