Web. Werdis (2006/7) – What is it? Web Weather Request and Distribution System, Web. Werdis, 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. DWD. 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_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 3/19/2018 S.

Web. Werdis (2006/7) – Relation to WIS Web. Werdis 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: – Web. Werdis 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-WISIII/Doc 3 -1(3)WIS-Com. Structure. doc) – Metadata structures are be based on the recommendation of the “CBS INTERPROGRAMME EXPERT TEAM ON METADATA IMPLEMENTATION“, http: //www. wmo. int/web/www/WDM/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/) 3/19/2018 S. Fechner, DWD, siegfried. fechner@dwd. de 2006, November
Web. Werdis (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 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_Final_report. doc). Important requirements are: 1. the appropriation of the main catalogues (e. g. WMO Meteorological Bulletins Volume C 1 and Volume A) and 2. the redesign of the DWD-internal product and station catalogues as ISO-19100 documents. – Incorporation of the main components of Web. Werdis into the VGISC/SIMDAT project 3/19/2018 S. Fechner, DWD, siegfried. fechner@dwd. de 2006, November
