Abstract

Users of scientific databases need descriptional information for understanding the definitions, abbreviations, acronyms, and genealogy of data stored and maintained in a database management system. This type of knowledge or metadata includes a wide range of information to help users locate, access, browse, clean, and aggregate databases. In this paper we describe the RAND Metadata Management System (RMMS), which is the result of a project to develop and implement specifications for storing and maintaining descriptional metadata. RMMS promotes the sharing, reuse, and interoperability of scientific data by improving five major DBMS data administration activities: documentation, version management, history management , derived databases, and standard data elements. We discuss the motivation for the development of RMMS, the functionality of RMMS, and its implementation architecture.
