Since 1.5 years we work on a vision to establish an enterprise model repository. The models should capture the important knowledge of our enterprise.
The overall meta model is
- an assembly of individual meta models
- properly layered (avoid cyclic dependencies)
As repository technology, we use CDO. Our main requirements are:
- Scalability
- Collaboration
- Temporality
- Model Evolution
Model Evolution is still a open issue. We are looking for partners to make model evolution reality.
