Abstract

The next generation GPS (Geometrical Product Specification and Verification) is a very important basic technique standard system for manufacturing. It has been developing by ISO/TC 213 since 1996. But it is an intricate and abundant information system for engineering application and causes the problem of popularized usage. An integrated information system of the next generation GPS is proposed in this paper. For data modeling of next generation GPS information system, a new modeling method based on category theory is put forward and called GDM (Geometrical Data Model) in the paper. An important advantage of the method lies in its configurable semantics which can make the structure relationship clearly amongst the meta knowledge of standards issued or revised by the ISO/TC213, and by this method, features such as null values, uncertainty and temporal behavior can be added easily by selecting appropriate instance categories.
