The Xholon project explores: software as systems of linked nodes, organized hierarchically. The Xholon toolkit supports this back-to-basics approach, and demonstrates practical benefits through examples from numerous domains.
The aXBench (AUTOSAR extensible workbench) is a free eclipse plugin for modeling variant system architectures.
This project collects modeling examples for the aXBench without having ti deal with the source code of the aXBench.
