Gnowsis Development Site

welcome to gnowsis, the Semantic Desktop environment published by the Knowledge Management Lab of the DFKI. Gnowsis can be used in research projects or by interested individuals to benefit from Semantic Web technologies. Gnowsis was brought forward in the BMBF-project EPOS and is continued in the EU project NEPOMUK.

Here you find most documentation on current gnowsis development and our workplace for future releases. The main website of gnowsis is

Alpha VS Beta

Gnowsis has been alpha until Februar 2006. We stopped working on the alpha code and now concentrate on the beta, which is partly a re-write. You will find documentation related to the alpha and beta versions.

How to Use Gnowsis?

Understanding gnowsis?

Developing Gnowsis?


There are several sub-projects and related projects that we use/work on to make gnowsis run:

Subversion Access


Gnowsis Workshops. Continually, we do workshops on the Semantic Desktop in Germany, there have already been two, one is planned. Next Workshop:

Past Workshops


IRC served us well. Many SemWeb people have accounts on freenode, to hang out in #swig. Clients:

Development Mailinglist:

General Information Mailinglist

We also talk to each other via tickets and the Roadmap.

Where is gnowsis coming from? where will it go? Gnowsis started in June 2002 when Leo Sauermann decided to make a diploma thesis about cyberspace. Well, cyberspace went down and gnowsis came up. At the beginning of 2003, it was dark ages of Semantic Web. The Aurora project just went down and many frameworks out there, but less apps. RDFSuite was a kind of state of the art. at 19th of may 2003, the first listStatements call went through the FileAdapter, marking our beginning of Virtual RDF Graphs. The first prototype ran in 2003 and the thesis was published 2003. 2004 Leo Sauermann went to DFKI and the project went public in September 2004. It was integrated into the EPOS project and tools like the Brainfiler. At the end of 2005, we are standing before the step to beta 0.9: three years of fumbling should now lead to a useful tool.

  • Roadmap - the current roadmap of gnowsis, what features to develop next, what bugs to fix. This is built from tickets.
  • GnowsisProjectPlan - the plan what features we will do in the next year, who does what and why. Here you find use-case descriptions, features, GUI mockups, detailed package descriptions and unit descriptions.
  • GnowsisBrainstorm - what to do next with the gnowsis? Here we list ideas, that are not included in the project plan yet.

The goal for gnowsis during 2006 is to publish a useful, self containing beta version in February. All features and todos of this beta can be found here: milestone 0.9 beta. This release will be build from scratch again, using a fresh project and seperating the components in a different way. We will still use our battle-proven DFKIWorkspace service launcher (OSGI remains outside), but dependencies to MySQL and other external apps will be removed. A personal semantic wiki is the most important goal, we moved from using snipsnap away to using JSPwiki as the basis. The semantic wiki/blog will be Kaukolu-Wiki, another nice move of DFKI.
