In this paper we deal with problems occurring in evolving interrelated Web databanks. Examples of such databanks are networks of interlinked scientific repositories on the Web, man...
Versioning systems such as CVS exhibit a large potential to investigate and understand the evolution of large software systems. Bug Reporting systems such as Bugzilla help to unde...
