A Frame-based design for the TIMS and CAMS metadata for a stennis information management system

Abstract The satellite platforms of the Earth Observing System that the National Aeronautics and Space Administration plans to launch in the late 1990s has required that the automatic cataloguing and archiving of data be studied. Because of the tremendous volume of data, use of artificial intelligence techniques and tools is required. The data that is to be archived must be evaluated and a metadata design created for the efficient access of the archived data. This article discusses a frame-based metadata design. In this approach, the relationships between the data objects and the data components are represented using a semantic network and frames. Previous object-oriented designs have only been able to represent hierarchical relationships, but this frame-based design allows for a more complete definition of data and the objects' relationships.
