  5. Architecture – Future Developments • Future development should begin with defining scenarios for decision support needs of GEOSS Societal Benefit Areas. The core architecture should then be refined based upon these needs as defined by the GEO Committees (in particular the UIC), Communities of Practice and other relevant GEO Tasks. • Architecture definition should continue, including: development of scenarios using an enterprise modeling approach; further definition of workflow for observation processing and decision support; and, extend the architecture to include observation nodes to support such use cases as inter-calibration. • Operational requirements should be identified including decisions on resources allocation, commitments, persistency and governance that recognize and supplement the voluntary contribution nature of GEO.
