SIMDAT / NESC Workshop Sept 05 11 SIMDAT V-GISC Gil Ross Met Office V-GISC – SIMDAT
12
SIMDAT / NESC Workshop Sept 05 12 SIMDAT V-GISC vGISC Instead of each National Met Service having a GISC (Global Information System Centre) a “distributed” or “virtual” GISC 3 NMSs – Meteo France Deutcher Wetterdienst DWD Met Office UK – MetO and two DCPCs Data Collection and Production Centre ECMWF EUMETSAT
13
SIMDAT / NESC Workshop Sept 05 13 SIMDAT V-GISC SIMDAT 4 years project funded by the EU Contract with EU was signed on 1 September 2004 Data Grids for Process and Product Development using Numerical Simulation and Knowledge Discovery SIMDAT focuses on 4 application area: product design in automotive and aerospace, process design in pharmacology service provision in meteorology Budget of 11 M € of which 10.5% for meteorological activity project managed by ECMWF

SIMDAT / NESC Workshop Sept 05 14 SIMDAT V-GISC SIMDAT - Consortium
15
SIMDAT / NESC Workshop Sept 05 15 SIMDAT V-GISC SIMDAT Seven Grid-technology areas have been identified to achieving SIMDAT objectives: Integrated Grid infrastructure offering basic services to applications Access to data distributed on Grid sites Management of Virtual Organisation Workflows Ontologies Integration of analysis services Knowledge Services Not all will be addressed in Meteo - SIMDAT
16
SIMDAT / NESC Workshop Sept 05 16 SIMDAT V-GISC SIMDAT - Strategy. Virtual Data Repository. Introduction of grid technologies research The heart of the issue is data Phase 1 : Connectivity Phase 2 : Interoperability Phase 3 : Knowledge. Deployment of Grid infrastructure with particular attention to data transport and management.. Distributed DB access Workflows for next- generation aggregated knowledge capture, discovery and mining.
17
SIMDAT / NESC Workshop Sept 05 17 SIMDAT V-GISC SIMDAT - vGISC vGISC working groups adopted by SIMDAT (meteorology) SIMDAT is a technical solution for vGISC type operations will NOT deliver a vGISC has specified requirements similar to vGISC is investigating a vGISC Virtual Organisation is developing catalogue operations has developed message infrastructure SIMDAT 18 month test system due - NOW!

21
SIMDAT / NESC Workshop Sept 05 21 SIMDAT V-GISC VGISC Demonstrator: UKMO local db (2) Local database is a derivative of JEDDS – the ‘Joint Environmental Dynamic Data Server’ Originally developed by Met Office to provide data on demand to UK military Features: Live data feed; continuously refreshed Serving global TAF, METAR & GRIB bulletins Request-oriented SOAP web-service interface

SIMDAT / NESC Workshop Sept 05 23 SIMDAT V-GISC Catalogue Status in Test system
24
SIMDAT / NESC Workshop Sept 05 24 SIMDAT V-GISC Working decisions (1) Teleconference, wiki & email used for remote collaboration focus on HOW the catalogue operates, not the minutiae of metadata standards use a ‘random’ UID scheme and not try to ‘overload’ identifiers with semantics use a simple ‘Google-like’ and/or directory-based search interface 3 classes of search – by Keyword, time and/or location ignore internationalisation for now Issue: WMO Core (& ISO19115) is TOO flexible – there are too many options for spatial & temporal descriptions … we need best practice ‘application schemas’
25
SIMDAT / NESC Workshop Sept 05 25 SIMDAT V-GISC Working decisions (2) Metadata create linking schemas using the WMO Core Profile by using additional namespaces (i.e. ) metadata documents should be split into a ‘hierarchy’ of XML ‘fragments’ are used within the catalogue model for merging metadata fragments will uses Java templating rather than an XSLT-based approach … key issue to demonstrate the concept is WHAT the fragments are not the mechanics of HOW they are merged. This position may be revised post-demonstrator Agreement: nomenclature … a specific SYNOP (12:00UTC, 16/06/05 at Heathrow) is an instance the SYNOP ‘product’ is a generalised instance that requires instantiation parameters to identify a specific synop instance
