The National Institute of Standards and Technology (NIST) performs calibrations that achieve the highest level of measurement quality for the makers and users of precision devices world-wide. The information system that administers these calibrations
A new conceptual data model that addresses the geometric dimensioning and tolerancing concepts of datum systems, datums, datum features, datum targets, and the relationship among these concepts, is presented. Additionally, a portion of a related data model
Today's electronics manufacturers are expected to reduce their time-to-market cycles and lower total costs simultaneously. Product development cycles and volume ramp-up times are rapid, and corresponding end-of-life production is dramatic. This environment

This report provides an overview of a recent workshop held at NIST in Gaithersburg, July 15-17, 1999, on Electronic Commerce of Component Information. The report summarizes the discussions following the workshop's panel sessions and the plans for follow-on
Printed circuit assemblies (PCA) typically are designed on computer aided design (CAD) systems, checked, then released for manufacture. The released design description typically consists of a top assembly drawing and a series of data files which are used

The unifaction of robust enabling technologies of the Internet and ubiquitous access is resulting in market dynamics that change the way business is being conducted by electronic manufacturing services (EMS) providers. OEM/EMS enterprise relationships are
A conformance test module (CTM) for the GenCAM file format is being developed by National Institute of Standards and Technology to support an industry effort to develop the GenCAM standard. GenCAM is a product data exchange standard for information used in

The following paper traces the history of product data exchange standards from the physical model through electronic representations such as IGES. This paper provides an understanding of the early efforts leading to ISO 10303--Standard for the Exchange of
This paper details the assumptions, decision processes, and conclusions reached during the development and implementation of a Conformance Testing Tool using the JAVA [JAVA] programming language, and the Object Management Group's (OMG's) Common Object
