Abstract: The Gemini Science Archive (GSA) is a new science archive developed by the Canadian Astronomy Data Centre (CADC) to provide the scientific community with tools for effective on-line access to data collected by the Gemini telescopes. CADC has developed a MetaData Data Dictionary (MDDD) for the GSA to meet the goal of providing dependable and consistent archive data. This MDDD defines the rules that govern data manipulation on meta-data obtained from a variety of data sources. The MDDD is specified in XML, and so provides flexibility while reducing source code maintenance. The paper will discuss the rules that may be specified for the data sources and individual meta-data attributes, the role of the data dictionary in populating the GSA, verification of the consistency of the dictionary itself, and possible future improvements in the data dictionary.
