The paper describes an open architectural concept under development by NASA for EOSDIS which supports site autonomy and independent, evolutionary development of components to improve the services offered to users. This concept is intended to ensure that EOSDIS' data sets and services can form part of a future international earth science system, but also offers several advantages for the future evolvability of the system itself. 1. INTRODUCTION INASA's Earth Observing System (EOS) is a long-term, multi-disciplinary research mission to study the processes leading to global change and to develop the capability to predict the future evolution of the Earth system on time scales of decades to centuries (Asrar and Dokken, 1993). The EOS Data Information System (EOSDIS) provides computing and network facilities to support the EOS research activities, including data interpretation and modeling; processing, distribution, and archiving of EOS data; and command and control of the spacecraft and instruments. Although EOSDIS will eventually contain an enormous amount of valuable Earth science data, there are other sources of information that are essential to the study of climate change. Of critical importance are holdings of other Global Change agencies, such as NOAA, USGS, etc. and other international organizations. The Inter-Agency Working Group for Data Management for Global Change Data (IWGDMGC) are currently in the process of defining the Global Change Data and Information System (GCDIS) intended to provide linkages between data services through a common set of interoperability services. NASA is actively participating in these efforts. In addition, there is also a growing interest by earth scientists in the possibility of developing information systems for earth science data which not only encompass the major data repositories but also enables users to take an active part in the information system, by providing data/services to the system (i.e. UserDIS). This approach * The work of the first two authors was funded as part of the Hughes Applied Information Systems contract to NASA for the EOSDIS Core System Project (contract NAS5-6000) 31 seeks to encourage the scientific return from the investment in data and information systems by ensuring that the scientists are an integral part of the system Although NASA does not have the responsibility for developing either GCDIS or UserDIS it wants to make sure that its development of EOSDIS can support both of these evolutionary paths. This implies taking an architectural direction which opens EOSDIS so that it can be included within wider data systems and identifying architectural components which EOSDIS might contribute to these systems. The remainder of this paper discusses EOSDIS relative to GCDIS/UserDIS This paper summarizes the results of NASA's preliminary architectural investigation, currently in progress. This paper presents high level user issues related to a generalized data and information system followed by an outline of an architectural concept for such a system. This is followed by a discussion of the major issues that would need to be resolved for the development of such a system. 2. ARCHITECTURAL ISSUES The nature of Global Change and earth science research in general lead to some key architectural drivers for a data and information system to support this research: * The organizations which participate in the network are autonomous entities, and the architecture should intrude upon autonomy to a minimal extent. For example, the architecture cannot dictate how organizations will manage their data, their networks, and their users internally.
