Package Structure#

d3web defines the general package structure as follows:

de.d3web/knowwe.<core/pluginname>.<component>.<module>?.<subpackage>*.<Classname>

The core consists of non-optional classes, whereas plugins includes optional classes. A plugin usually spans over multiple components.

For example, the package structure of the XCL problem-solver:

• de.d3web.xcl: for the basic representation
• de.d3web.xcl.inference: problem-solver functionality
• de.d3web.xcl.io: problem-solver specific persistence
