Abstract

Science missions and instruments continue to produce volumes of useful data and scientists depend on the data systems and tools that archive this data as a means to access and analyze it. These existing legacy systems do not interoperate well, and scientists must access each data system and its corresponding science data independently through tools that have been custom-built for the particular science data system or mission. The Object Oriented Data Technology (OODT) task is working on the distributed resource location service, which will allow location and exchange of geographically distributed data. Advances in Internet and distributed object technologies provide an excellent framework for sharing data across multiple data systems. The Extensible Markup Language (XML) and the Common Object Request Broker Architecture (CORBA) provide support for electronic data interchange (EDI) between heterogeneous data sources. CORBA provides the over-the-wire exchange of XMLbased profiles that contain descriptive information of science products archived at remote data systems. This paper discusses a framework for data system interoperability that will not only benefit space science, but provide a cross-disciplinary solution for a next generation data system architecture.
