What matters in the end is that the target platform is able to (de)serialize Kevoree models from (and to) JSON strings.
The JSON format must comply with this JSON Schema.
A real life scenario is the development of the C# platform. No generator exists for this platform, but C# paradigms are very close from Java's one so we had been able to use IKVM, a tool to convert JARs to DLL.
The whole process is detailed here.
From our experience, the generated DLL is working really well but we had a hard time figuring out how to integrate it with the isolated contexts needed to load components into a node.
