  1. Web Weather Request and Distribution System (WebWerdis (2006/7)) Fechner, Siegfried (siegfried.fechner@dwd.de) Contents: – WebWerdis – What is it? – WebWerdis – Design and components – WebWerdis – Relation to WIS S. Fechner, DWD, siegfried.fechner@dwd.de 2006, November

  2. WebWerdis (2006/7) – What is it? Web Weather Request and Distribution System, WebWerdis, is a new generation of internet based distribution system. It is one part of redesigned Meteorological Portal of the DWD (start in 2007; preoperativ installation: “http://werdis-cbs.dwd.de/bvbw/bvbwDWD.portal”). Aims: – Accommodation of special usergroups with meteorological data and products (delivery via pull and push/subscription mode) – Harmonisation of the metadata (product, distribution and customer catalogues) of the currently main distribution tools of the DWD (based on on the recommendation of the “CBS INTER-PROGRAMME EXPERT TEAM ON METADATA IMPLEMENTATION“, http://www.wmo.int/web/www/WDM/IPET-MI-II/IPET-MI-II_Final_report.doc) – Unification of the request/response interfaces between the distribution tool and the different datasources as well as production tools of the Deutscher Wetterdienst S. Fechner, DWD, siegfried.fechner@dwd.de 2006, November

  3. WebWerdis (2006/7) – What is it? Technical standards: Programming – Java (jdk 1.4 or 1.5), jakarta struts 1.1, EJB 2.0 – Opensource components: AFD http://www.dwd.de/AFD quartz http://www.opensynphony.com/quartz OGSA-DAI http://ogsadai.org.uk Metadata design – Product and product instance catalogue (WMO-core metadata standard “formal draft version 1.0”; 2005, St. Petersburg) Server – Webfrontend (Bea-Portal, Weblogic 8.1.5) – Web-Business-components (each J2EE-container/server) – OGSA-DAI-gridservice (servlet or J2EE-container/server, e.g. Tomcat or Oracle Applicationserver) – Database (Oracle 9i XML-DB) S.

  20. WebWerdis (2006/7) – Relation to WIS WebWerdis is not a prototype of an GISC or VGISC. The primary aim was the development of a modern internet based request and distribution system as part of the redesigned DWD Meteorological portal. but: – WebWerdis design is geared to the design principles for the WIS data communication structure of the “INTER-COMMISSION COORDINATION GROUP ON THE WMO INFORMATION SYSTEM, THIRD Session” (http://www.wmo.int/web/www/ISS/ICG-WIS-III/Doc3-1(3)WIS-ComStructure.doc) – Metadata structures are be based on the recommendation of the “CBS INTER-PROGRAMME EXPERT TEAM ON METADATA IMPLEMENTATION“, http://www.wmo.int/web/www/WDM/IPET-MI-II/IPET-MI-II_Final_report.doc) – Structure and implementation would be incorporate into future WIS distribution tools (e.g. VGISC/SIMDAT- or UNIDART-project: http://www.ecmwf.int/services/grid/simdat/wiki/do/get/simdat or http://www.dwd.de/UNIDART/) S. Fechner, DWD, siegfried.fechner@dwd.de 2006, November

  21. WebWerdis (2006/7) – Relation to WIS Next planned adjustments: – Extension of the range of data and products (currently range: climatological information from selected stations across Germany, Norway, Finland and the Republic of Korea; Weather messages in accordance with the international exchange of data and a selection of satellite images, of weather forecast charts and of analytic-data) – Redesign of all metadata catalogues to bring them into agreement with the recommendation of the “CBS INTER-PROGRAMME EXPERT TEAM ON METADATA IMPLEMENTATION“, http://www.wmo.int/web/www/WDM/IPET-MI-II/IPET-MI-II_Final_report.doc). Important requirements are: as ISO-19100 documents. – Incorporation of the main components of WebWerdis into the VGISC/SIMDAT project 1. the appropriation of the main catalogues (e.g. WMO Meteorological Bulletins Volume C1 and Volume A) and 2. the redesign of the DWD-internal product and station catalogues S.
