ABSTRACT
A conceptual framework for the design, implementation and operation of scientific information systems has been developed. This framework is based on experience with focused field experiments, long-term data archiving and data publication. The elements of the framework include management and organizational constraints, the requirements of the scientific community, the flow of data from source to archive and resource requirements. Examples of these principles, drawn from successful information systems experience with the FIFE Information System and the Pilot Land Data System, are discussed.
