Presentation Transcript

  1. CIM – The Common Information Model in Climate Research Michael Lautenschlager, Hans Ramthun(World Data Center Climate / Max-Planck-Institute forMeteorology) and METAFOR Project Team Networking Event for European Research Infrastructures + Standards Workshop October 1 – 2, 2009, Helsinki

  2. METAFOR Partner • 11 partners • Started March 2008, duration 3 years • NCAS, University of Reading, UK (Coordinator) • BADC, Science and Technology Facilities Council, UK • CERFACS, France • Model and Data, Max Planck Institute for Meteorology, Germany • Institute Pierre-Simon Laplace, CNRS, France • University of Manchester, UK • Met Office, UK • AdministratiaNationala de Meterologie, Romania • Météo France, CNRM, France • CLIMPACT, France • CICS, Princeton University, USA

  3. METAFOR Objectives Create a standard metadataCommon Information Model (CIM) to describe climate data and the models and experiments that produced those data • Allows essential data, model and experiment distinctions to be understood • Builds on existing metadata standards used internationally in climate (CF, CDML, CSML, Curator, NMM, FLUME, ISO etc.) • Uses existing format and framework (XML, RDF, etc.)

  4. METAFOR Objectives Develop, deploy, and evaluate a prototype infrastructure that will allow key data and models to be discovered and compared between distributed digital repositories • single sign-on services to populate and manipulate, the CIM metadata • services exploit NDG CSML to provide a common Geographic Markup Language interface to climate data • centralized CIM content harvested from individual repositories using OAI-PMH (Open Archives Initiative Protocol for Metadata Harvesting).

  5. METAFOR standards definition International Emerging Community Discovery metadata ISO 19139 ISO 19115 Climate Modelling gridspec - model discretisation Sensor ML - observations NMM - model description CERA2 - data management Data CF for netcdf • Metafor will coordinate • filling of metadata gaps • mapping to different standards • aggregating the metadata • creating new standards (if necessary)
