2 Workflow Session Draft Agenda –Scenario outline (with links to Disaster Management, Sensor Planning Services and Processing) - all –Overview of available tools and identified issues - Y. Coene Spacebel, R. Lucchi JRC –Discussion and Planning - all –AOB –Adjourn

3 Workflow Session Requirements over Scenarios: –End-to-end scenarios should include Data requirements: –archived data –to be acquired »systematic »tasked –From satellite (Optical, Radar, Meteorological,…) –In-situ –Geospatial and other (demographic, protected areas, etc…) User Requirements on –data access (which data sources, update frequency, quality,…) –results and information exploitation (output formats, presentation requirements,…) Interaction Diagrams indicating actors, endpoints, operations to be supported by the Workflow

5 Workflow Session: Tools –Please list and detail proposed/available tools e.g.: From FEDEO in 2007 Persistent Testbed available at including –workflow engine –clients for: »ISO and EO Ebrim extension package catalogues, »CSW ISO Profile »Sensor Planning Service EO Profile »Sensor Observation Service »EO order profile »WMS and simple feature WCS, WFS Open Source Skeleton sw to simulate and build servers Dedicated forum to be set up for planned activities
