Version control is one of the most important functions which need to be supported in integrated computer-aided design (CAD) systems. In this paper we address a broad spectrum of semantic and operational issues in version control for a public/private distributed architecture of CAD systems. The research issues we address include the semantics of version creation and manipulation, version naming and name binding, and version change notification. We develop solutions to these issues under a unifying framework, and discuss implementation and application interface issues.
