SIMDAT / NESC Workshop Sept SIMDAT V-GISC Gil Ross Met Office V-GISC – SIMDAT

SIMDAT / NESC Workshop Sept 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

SIMDAT / NESC Workshop Sept 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 SIMDAT V-GISC SIMDAT - Consortium

SIMDAT / NESC Workshop Sept 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

SIMDAT / NESC Workshop Sept 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.

SIMDAT / NESC Workshop Sept 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!

SIMDAT / NESC Workshop Sept SIMDAT V-GISC VGISC Demonstrator: UKMO local db (1)

SIMDAT / NESC Workshop Sept 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 SIMDAT V-GISC Catalogue Status in Test system

SIMDAT / NESC Workshop Sept SIMDAT V-GISC Working decisions (1) Teleconference, wiki & 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’

SIMDAT / NESC Workshop Sept 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
