An infrastructure for development of object-oriented, multi-level configuration management services

In an integrated development environment, the ability to manage the evolution of a software system in terms of logical abstractions, compositions, and their interrelations is crucial to successful software development. This paper presents a novel framework and infrastructure, Molhado, upon which to build object-oriented software configuration management (SCM) services in a SCM-centered integrated development environment. Key contributions of this paper include a product versioning model, an extensible, logical, and object-oriented system model, and a reusable product versioning SCM infrastructure, that allow new types of objects to be implemented as extensions of the system model´s basic entities. Versions and configurations of objects are managed at different levels of abstraction and granularity. A new SCM-centered editing environment or development environment for a specific development paradigm can be rapidly realized by re-using Molhado´s infrastructure and implementing new object types and their associated tools. This paper also demonstrates our approach in creating prototypes of SCM-centered development environments for different paradigms.
