Evolution status and plans for NSIDC DAAC EOS Core System (ECS) Vince Troisi 1 PoDAG 25: Data Systems Evolution status and plans for ECS: EOSDIS Evolution 2015 Vision Tenets Vision Tenet Archive Management EOS Data Interoperability Future Data Access and Processing Data Pedigree Cost Control User Community Support IT Currency Vision 2015 Goals NASA will ensure safe stewardship of the data through its lifetime. The EOS archive holdings are regularly peer reviewed for scientific merit. Multiple data and metadata streams can be seamlessly combined. Research and value added communities use EOS data interoperably with other relevant data and systems. Processing and data are mobile. Data access latency is no longer an impediment. Physical location of data storage is irrelevant. Finding data is based on common search engines. Services invoked by machine-machine interfaces. Custom processing provides only the data needed, the way needed. Open interfaces and best practice standard protocols universally employed. Mechanisms to collect and preserve the pedigree of derived data products are readily available. Data systems evolve into components that allow a fine-grained control over cost drivers. Expert knowledge is readily accessible to enable researchers to understand and use the data. Community feedback directly to those responsible for a given system element. Access to all EOS data through services at least as rich as any contemporary science information system.
