Development
We are using Eclipse OSGI projects/plugins as project format. The reason for this is to be able to export the whole framework either as a normal Jar or as an OSGI plugin, which allows you to easily use the framework within RCP applications. Actually, both distribution ways are the same, its always the same jar.
To develop, you need
- gnogno2go and Eclipse
- read EclipseDevelopment.
Currently, much is missing or in a limbo state, because of the move to RDF2Go and to a slimmer architecture, but the code is getting cleaner every day.
Using GnoGno in NEPOMUK and PSEW
GnoGno is the framework used by PSEW to represent objects in-memory for visualization. To use GnoGno for NEPOMUK, you can first get familiar using the documentation mentioned above, and then read
- GnognoInPsew
- You should use EclipseVisualEditor to create GUIs!

FAQ
Q:How to automatically create GUIs using gnogno?
A:GnoGno has automatic resource renderers. One is the RDFResourceRenderer in SWT. These components should interpret fresnel descriptions, but they don't do yet. The fresnel configuration has to be done on the level of GnoFactories, its valid accross a whole application. Additionally, property ranges are read by some of the GUI components to correctly format values and set the correct datatype URIs in created statements. The Method getDatatype() does this.
