  2. General project information • UNIDART is a EUMETNET Programme and DWD is the Responsible Member • UKMO and KNMI are initial project partners • start in 2001 with a feasibility study • start of prototype development in 2003 • prototype software is installed at DWD, met.no, FMI and KMA • installation planned at KNMI, MeteoSwiss, ZAMG and JMA • test version of this software can be downloaded from UNIDART web site http://www.unidart.eu (see folder “Software & Tools”) Friday, 20 December 2019 - 2 -

  3. The main goal of UNIDART which store any kind of meteorological data and products Development of a Web-based information system that allows a uniform and integrated access to heterogeneous and distributed data sources Friday, 20 December 2019 - 3 -

  4. 4 Steps to reach the Goal • define data categories, e.g. climate time series, forecasts, satellite data, etc. • develop a query syntax for each data category • specify metadata templates to describe data sets of each data category • write a web service for each data category Friday, 20 December 2019 - 4 -

  7. 4 Steps to reach the Goal • define data categories, e.g. climate time series, forecasts, satellite data, etc. • develop a query syntax for each data category • specify metadata templates to describe data sets of each data category • write a web service for each data category Friday, 20 December 2019 - 7 -

  8. Data policy A data provider decides : • from which machines data requests are accepted • which users will be authorised • which data sets are offered for download The access to data is controlled by the provider ! Friday, 20 December 2019 - 16 -

  9. Advantages for a data provider • provide data together with other data centres increases satisfaction of users • UNIDART can be used for the implementation of WIS • connect to other data grids / applications • participate on the built-up of a service-oriented architecture amongst meteorological centres Friday, 20 December 2019 - 20 -
