Abstract:
EXPRESS is the official information modeling language of the next generation of product information standards, commonly referred to as STEP. This paper presents a Structural EXPRESS Editor, which has two parts: an Interactive Editor, and a Transition Module. The Interactive Editor was built using a tool called the Data Probe Editor Builder and is an interactive, friendly editor with which a user defines the structure of an EXPRESS schema. The output of the Interactive Editor is a STEP exchange file that is translated into EXPRESS by the Translation Module, a software system written in LISP.

The paper describes the Data Probe Editor Builder and both parts of the Structural EXPRESS Editor. The editor is assessed and EXPRESS editor, generally, are discussed. Alternative representations of EXPRESS are presented. A few issues in information modelling highlighted in the course of building the editor are discussed.
