The SC4 Short Names Registry



Joshua Lubell


This paper describes a software environment recently implemented for maintaining a registry of unique short names for each of the entity data types within each of the EXPRESS schemas in the ISO TC184/SC4 standards. The new environment replaces an inefficient application and has already provided time savings for both the registry''s administrator and editors of SC4 standards. It is also improving the quality of SC4 standards. The new SC4 Short Names Registry resides on a server at NIST and uses an SQL database engine in conjunction with the NIST EXPRESS Toolkit. Two applications have been developed for accessing the Short Names Registry. An application for end users that is accessible using the World Wide Web allows individuals to view SC4 part summary information and entity long names and short names in a variety of useful formats. An application for database administrators supports the insertion, deletion, and modification of SC4 parts.
