  1. GO-ESSP Seattle 2008 Principle Investigator : Eric Guilyardi IPSL/Reading Lois Steenman-Clark NCAS, University of Reading Leader of METAFOR Work Package 2

  2. Facts and Figures METAFOR Common Metadata for Climate Modelling Digital Repositories EU FP7 e-infrastructures project 11 partners Total budget of 2.2M€ Starting in March 2008, duration 3 years The principle aim of METAFOR is to develop a Common Information Model (CIM) to describe in a standard way the climate data as well as the numerical models that produce this data.

  3. Partners NCAS, University of Reading, UK (Coordinator) BADC, Science and Technology Facilities Council, UK CERFACS, France Models and Data, Max Planck Institute for Meteorology, Germany Institute Pierre-Simon Laplace, CNRS, France University of Manchester, UK Met Office, UK Administratia Nationala de Meterologie, Romania Météo France, CNRM, France CLIMPACT, France CICS, Princeton University, USA

  4. Vision of An Information Model that is common for all stages of both production and the use of climate model data. Tools that populate, create, manipulate, convert and exploit this Common Information Model to allow climate models and climate model data to be inter-comparable and sharable. CIM Common Information Model based on current, emerging and new metadata standards (CIM - Common or Climate Information Model ?)

  5. has 286 person months of effort WP 6 CIM creation tools CIM Common Information Model WP 2 WP 3 Verification WP 4 Data Portals WP 5 CIM exploitation tools

  6. Common Metadata for Climate Modelling Digital Repositories GO-ESSP Seattle 2008 • metafor is not just about the metadata but also about • being able to gather or create the metadata • building diverse repositories • enabling and designing tools to exploit the metadata

  7. GO-ESSP Seattle 2008 UML Climate Modelling An activity using software and data creating data to be housed in a repository. Conceptual Model XSD Application Model Application Model RDF XML Instance @ BADC An essential aim of metafor is that the conceptual model is not changed by the manor in which it is used or applied. Instance @ IPSL Instance @ PCMDI Common Metadata for Climate Modelling Digital Repositories

  8. Common Metadata for Climate Modelling Digital Repositories GO-ESSP Seattle 2008 • The information modelling of the climate modelling process requires • a degree of commonality • with community agreement to achieve this • governance mechanisms to develop and maintain this • extensions for local use or translations to other systems community common The ‘fried egg’ implementation of the information model

  9. GO-ESSP Seattle 2008 UML package diagram grid quality Activity Software Data Re-usable entities With a clear understanding of package descriptions An Activity is an abstract package of project, ensemble, campaign, investigation. Data in all its guises and usage within the climate modelling process. Software which includes all parts of the activity that takes place on a computer. Grid ie gridspec Quality measures that could be applied to activities, software or data. Re-usable entities for example responsible person, defined within ISO. • and the aim to achieve • a separation of concerns • encouragement of interested parties to participate in discussion • ensuring a degree of governance • a mechanism for separate development UML class diagram + dictionary

  10. Vn 3 Vn 2 Vn 1 Vn 3 Vn 2 Vn 1 GO-ESSP Seattle 2008 Why is separate development necessary? Package A • For climate modelling • the UML associations are complex • it is a diverse community • requirements evolve • tools exploiting the CIM take time and effort to develop • metafor, Curator, AR5 needsystems soon

  11. GO-ESSP Seattle 2008 Oct 2009 Oct 2010 Oct 2007 Oct 2008 Curator metafor AR5 metafor • for AR5 • CIM based data portals design and implementation • CIM to encompass AR5 • metadata requirements  Access to CIM tools and services • CIM verification  part of AR5 quality control • CIM tools for ingestion  tools made available to modellers • CIM exploitation tools

  12. Common Metadata for Climate Modelling Digital Repositories GO-ESSP Seattle 2008 Issues for discussion metafor timelines are tight, it is a 3 year project that wants to provide a community CIM and tools that survive and evolve beyond this project governance is slow and difficult there is the challenge of achieving generic community acceptance
