and information system models. It has also intensified awareness of two unavoidable conclusions: NASA is accountable for what happens to EOS data, no matter what information system is implemented, and the scientific community can recommend a structure and an approach but cannot decide what to do.
For the future we envision a federation that will be effective in transcending lists of requirements by providing enabling capabilities and by focusing on the value of EOS data for science and applications rather than on system mechanics. The operational details of the EOS information system will then fade into the background of an existing supportive, but largely invisible, global information infrastructure, and scientists will be able to concentrate on science.
