Kolab is a free and open source groupware suite. It consists of the Kolab server and a wide variety of Kolab clients, including KDE PIM-Suite Kontact, Roundcube web frontend, Mozilla Thunderbird and Mozilla Lightning with SyncKolab extension and Microsoft Outlook with proprietary Kolab-Connector PlugIns.
The special idea behind Kolab is the use of as an underlying not only for email, but also for contact and calendar entries. These entries are simply saved in special IMAP-folders utilising the Kolab XML-format and the IMAP-server takes care of the storage and access rights. The configuration and maintenance of Kolab is controlled by the extensive use of LDAP.
Kolab Clients and the Kolab server use well established protocols and formats for their work (i.e. IMAP as mentioned above, vCard, iCal, XML and ). This allows the Kolab Format specification framework, or even portions of it, to be utilized as an open set of specifications for groupware clients and servers to communicate with each other. Third party implementations began almost immediately; for example, the Citadel groupware server began supporting version 1 of the Kolab Format specification in March 2004.
The concepts on which Kolab relies are laid out in the Kolab Format Specification and Architecture Paper for Kolab 2, and for Kolab 1 in the Kroupware Contract, Architecture Paper and Technical Description.
