Abstract : The Product Data Exchange Specification (PDES) is an emerging standard for the exchange of product information among various manufacturing applications. The neutral exchange medium for PDES product models is the STEP physical file format. The National PDES Testbed at NIST has developed QDES, a window-based editor for STEP product models. The editor, written in Smalltalk 80, is schema-driven: in the Testbed context, an Express information model is used to describe the objects to be manipulated; QDES itself thus has no a priori knowledge of its domain. This document describes administrative procedures for QDES. Some architectural issues are also presented.
