Extending the UML to support evolution management

Summary form only given. The authors are currently developing a model-driven, repository-based approach to system evolution management. The primary domain of interest is the telecommunication IT system area, but the techniques are applicable to organizations with integrated systems of systems. The approach is model-driven in the sense that data and object-oriented (OO) models (expressed in the Unified Modeling Language (UML)) are used to represent system implementations at various levels of abstractions (business requirements, system requirements, logical and physical design).
