Extensions of the Prototype Application Protocol of Ready-to-wear Apparel Pattern Making
Yung-Tsun T. Lee
A prototype application protocol for ready-to-wear pattern making was developed for the communication of pattern pieces and related information between various CAD systems. The basic methodology for the application protocol is the Standard for the Exchange of Product Model Data (STEP). STEP is an emerging international standard, the result of an effort to develop a mechanism for digitally representing the physical and functional characteristics of a product throughout the product''s life cycle. The STEP application protocol addresses a specific application area and contains an information model written in the conceptual modeling language EXPRESS. The experience gained through the implementation of the prototype application protocol and recommendations received from apparel researchers provided us useful input to improve the prototype application protocol. This report presents a revised version of the information model using both the EXPRESS language and the EXPRESS-G graphical notation. An application activity model that defines the scope and information requirements of the prototype application protocol is also presented in this report. Neither the EXPRESS-G diagrams nor the application model was shown in the original prototype application protocol report.
