Status of PDES-Related Activities



Cita M. Furlani, Joan Wellington, Sharon J. Kemmerer


This report describes the standards and testing activities that relate to PDES (Product Data Exchange using STEP). PDES is the name given to the United States organizational activity that supports the development and implementation of the international Standard for the Exchange of Product Model Data, informally known as STEP. The definition of PDES was made more explicit in March 1990 by altering the meaning of the acronym from its earlier one, Product Data Exchange Specification. Much of the information in this paper was originally collected as part of the justification for a national initiative to implement automated product data sharing. Other papers describing product data sharing in various industrial sectors were also produced and the set will be published in late 1990.
