Gnowsis Development Site

welcome to gnowsis, the Semantic Desktop service environment published by the Knowledge Management Lab of the DFKI. Gnowsis is a reference implementation of parts of the Nepomuk Semantic Desktop framework. The ​Nepomuk project provides a standardized, conceptual framework for Semantic Desktops. 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 ​www.gnowsis.org.

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.

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

• ​miranda-im which leobard uses.
• mIRC is also well-known.

Roadmap

Gnowsis started in June 2002 when Leo Sauermann decided to make a diploma thesis about cyberspace. At the beginning of 2003, the first implementation was done in the dark ages of Semantic Web. RDFSuite was a kind of state of the art, Jena was in version 1. Based on the prototype, a diploma thesis was published in 2003. Leo moved to DFKI and the project was published in September 2004. It was integrated into the EPOS research project. Based on this experience, the ​Nepomuk project now develops a standardized, conceptual framework for Semantic Desktops, with gnowsis as reference implementation of parts.

• 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.
• ​Roadmap - the current roadmap of gnowsis, what features to develop next, what bugs to fix.
• GnowsisBrainstorm - what to do next with the gnowsis? Here we list ideas, that are not included in the project plan yet.
