Towards a model of versioning domain

Improvement in software development process is a permanent challenge in software engineering where version control systems are permanently supporting the process. For achieving follow improvement we need a better understanding of the versioning domain. Starting from granularity elaboration of versioned object in this article we shall try to actuate toward the issue of classification of versioned object according to their place in software development process. Moreover, the article is to be a trigger for augmentation the scope of versioning systems by supporting of trace links among versioned objects.
