  1. Earth Science Information Partner (ESIP) Federation:Semantic Web Activities(including SWEET) Rob Raskin NASA/Jet Propulsion Laboratory

  2. About ESIP • Networking Consortium of 121 US member organizations • Data, information, and service providers • Focus is on adding value to Earth system science data • Most activities are cross-disciplinary • Bottom-up activity plan driven by self-formed clusters/working groups • Monthly telecons • Semi-annual Meetings • Jan 2011 Washington, DC • July 2011 Santa Fe, NM

  3. ESIP Members • Type 1- Archive Centers • NASA, NOAA, USGS, EPA data centers • Type 2- Producers of Science/Research Data • Grant awardees from universities and government • Type 3- Applications • Commercial entities, educational organizations, decision makers • Type 4- Funders • NASA, NOAA

  4. ESIP Clusters/Working Groups Domain-Specific • Air Quality • Water Education/Outreach • Education Data and Informatics Decisions Federated Search Information Quality Information Technology/Interoperability Preservation and Stewardship Products and Services Provenance Semantic Web Sensor Web Visualization Web Services

  5. Semantic Web Cluster • Ontologies • Datatype • Data Service • Science/Applications (SWEET) • Triple store testbed • Test technologies • Link open data among members • Technologies, research activities

  6. Semantic Web for Earth and Environmental Terminology (SWEET) • Concept space written in OWL-DL • Serves as middle-to-upper level ontology for Earth system science • Enables scalableclassification of Earth system science and associated data and applications • Version 2.1 contains 6000 modular concepts • 200 modular ontologies

  7. Scope of SWEET • Integrated ontologies • Earth system science • Earth science applications • Scientific units • Space/time • Data quality • Data provenance • Data types • Data services

  8. SWEET Top-Level View

  9. SWEET Provides Set of Building Blocks CF (controlled parameter name list): tendency_of_mole_concentration_of_dissolved_inorganic_phosphorus_in_sea_water_due_to_biological_processes SWEET: • Property= mole_concentration • Science_Processing= tendency • State= dissolved, inorganic • Substance= phosphorous • Medium= sea_water • Process= biological_processes

  10. Governance • ESIP Semantic Web Cluster to provide overall governance • How? • MMI will provide further support through common ontology services (comparisons, access, archiving, etc.)
