Mission: To create, as a community, the leading open source groupware server to integrate with the leading open source office suite products and all the leading groupware clients running across all major platforms, and to provide access to all functionality and data through open XML-based interfaces and APIs.

Historical Background

MDlink GmbH, the original author of the reference server, was founded as an Internet service provider (ISP) in Germany in 1994. The company started development on the LSOffice application server in about 1996 to extend it's Internet offerings with a powerful collaboration platform usable over the Internet.

Some years later LSOffice was renamed to SKYRiX 3 and finally in 2000 a separate company, SKYRIX Software AG, was forked to concentrate on the further development of the product.

The SKYRiX Groupware Server is certainly one of the earliest GNU/Linux based groupware solutions (being now, in 2005, about nine years old).

The source code initially includes the technology SKYRIX Software AG has been developing for the future versions of the SKYRiX groupware server. The source is mainly written in Objective-C and delivers language-neutral and scriptable functionality, including XML interfaces.

Differences between and SKYRiX

Starting with the launch of, SKYRiX becomes an enterprise distribution of the software. That is, SKYRiX is a maintained selection of stable parts of the OGo sources.
The SKYRiX distribution also includes some additional software which is not available as part of the project, like:

  • Application Level Load Balancer (snsd)
  • Various other SKYRiX 5 User Interface Themes
  • Support for Oracle and Sybase databases
  • CTI Support for CSTA based telephone switches
  • Outlook Support for ZideStore

Licenses is free software and uses a single license per subproject, either the GPL or the LGPL. We think that LGPL provides enough freedom even for companies wishing to add functionality to closed source applications. [more info]
