Abstract
The National Institute of Standards and Technology (NIST) maintains a wide range of scientific and technical data resources, including free online data systems and PC databases available for purchase. However, many people are not familiar with these various NIST data collections and the types of data they contain. To help scientists, engineers, and the general public find out quickly and easily whether data they need are available at NIST, NIST has built a web portal to NIST data resources. The first version of this portal, the NIST Data Gateway (
http://srdata.nist.gov/gateway), provides easy access to 26 online NIST data systems and information on 48 NIST PC databases. NIST Data Gateway users can specify a keyword, property, or substance name to find the NIST data resources that contain standard reference data meeting their search criteria. When users find a data resource they want to use, links are provided so they can access or order that resource. In this paper, we describe how Version 1.0 of the NIST Data Gateway was built and discuss some of the issues that arose during the design and implementation stages. We include experience we gained that we hope will be useful to others building data portals. We also discuss future plans for the NIST Data Gateway, including efforts to provide access to additional NIST data resources.
