  1. Workshop on Information Access EnablersMétéo France Strategy Geneva 17-18 May 2010 Jacques Roumilhac

  2. Information access in Météo France • Stage 1: Current status • Okapi production platform (finalized products) with a Web portal • IAA (Random Access on Legacy databases) with a bespoke language via ftp • Stage 2: Information system evolution • SOA (with a part of OGC services) • Information model with geographic references • Spatial databases • Light and smart client (forecaster station project) • Stage 2 bis: WIS solution • OpenWIS developed with UKMO • Metadata generator

  3. Stage 1: Production Service Okapi - IAA • OKAPI: Three software bricks, loosely linked : • Okapi production platform (products factory). • Internal production portal : Okapimet (For web and webservice customers). • production portal : Climatheque (For web and webservice customers). • IAA • Random access • On the legacy databases • Archive access possible • With a bespoke language

  4. System schema

  5. orchestration, traffic shaping • Traffic shaping mechanisms • Balanced charge. • Product factory (close WTS) • Identity management (authorization, authentication)

  6. Stage 2: New project Synopsis: Forecaster tools based on SOA • Two main requirements • SOA • Development efforts factorization • Processing and data pool access • Standard interfaces • Management of different topologies (local or remote server, standalone) • WMO needs and INSPIRE recommendation • Client station • Last technologies • Deployment and support easy • Light or smart client • Scalable, efficient • Multi-platforms

  7. Technical choices • Synopsis Server : • Linux 64 bits : • Re-use of current services in different systems • Use of programs and libraries of ECMWF • Use of bricks OpenSource • Databases: PostgreSQL, PostGIS • Image processing: GDAL, Proj4 • Mapserver : services OGC • Geonetwork for the catalogue

  8. The services • Different service levels • Metadata access (catalogue) • Data access • Business processing (graphic processing) • Presentation services (images, maps, graphics…); • Interoperability for the map services • So : WMS (Web Map Service) et CSW (Web Catalog Service) • For INSPIRE, interoperability also on data and processing services (transformation and downloading) • So : WCS (Web Coverage Service) WFS (Web feature Service), WPS (Wep processing Service) ….

CRUD CRUD CRUD SOA : Reference architecture Engine Orchestration BPM Supervision Application composite Application composite Services Registry Application composite Business process SAM BAM Bus for messages Data access Business services Processing / Transformation Administration Plate-Form SAM : Service Activity Monitoring Legacy databases BAM : Business Activity Monitoring BPM : Business Process Management CRUD : Create Read Update Delete

  10. Web Coverage Server Web Feature Server Web Map Server Interoperability • Strategic target • Use of the standards • OGC standards for geo-referenced data • Web Map Service (WMS) • Web Feature Service (WFS) • Web Coverage Service (WCS) • Catalogue (CSW) • Geography Markup Language (GML) • Web Map Context (WMC) • OGC KML • Others…

  15. General Architecture • Data and services catalogue (standard) • On line products and services discovery. • Message bus • Balanced flow (cluster services) • Loosely link between server and client • Spatial database • Using MapServer and other OGC implementations • Standard interfaces used by the clients • Possibility to access to extern services (without guarantee of performances) • Useful for a wandering forecaster

  20. Stage 2 bis: WIS Approach • OpenWIS development : • Information fetching: Different use cases • OpenWIS: Open interfaces • Request or subscription • Météo France use two diffusion systems • Metadata GTS generator • To populate the WIS catalogue • Mapping between Volume C1 and Core Metadata Profile • Close the prompting question on information sources

  21. 7bis: the user receives the products. 1: the user discovers local product type in the catalogue FSS Ad-hoc Request for a product in the Cache – dissemination via the FSS (GISC function) 5bis: the user obtains the products from the shopping cart. 3: the user composes an ad-hoc request for the product type. The user specifies which products are of interest, and the chosen dissemination options. 4: The product type is part of the global dataset. The requested products are extracted from the Cache. 2: the user is authenticated (several steps) Portal 5: Storage in the shopping cart for an online distrbution, or preparation of the dissemination instructions: they are constructed from the user profile, among other elements. DAR subscriptions (user profile) 6: the products and instructions are forwarded. OpenWIS MSS 7: Dissemination according to instructions. Routing

  22. 8bis: the user receives the products. 1: the user discovers local product type in the catalogue FSS Ad-hoc Request for a local product – dissemination via the FSS (NC or DCPC function) 6bis: the user obtains the products from the shopping cart. 3: the user composes an ad-hoc request for the product type. The user specifies which products are of interest, and the chosen dissemination options. 4: the product type is owned by a local NC or DCPC. 2: the user is authenticated (several steps) Portal 6: Storage in the online shopping cart, or preparation for dissemination. DAR subscriptions (user profile) 7: the products and instructions are forwarded. OpenWIS 5: the required products are extracted and returned. SOURCE MSS 8: Dissemination according to instructions. Routing

  23. 6bis: the user receives the product. FSS Arrival of a new GTS product at the MSS (GISC function) 4bis: the user obtains the product from the shopping cart. 3: Is someone subscribed to this type of product ? Portail 4: Storage in an online shopping cart or preparation for dissemination: construction of the dissemination instructions. DAR subscriptions (user profile) 2bis: the product is collected and inserted in the GISC Cache 5: the product and instructions are forwarded OpenWIS MSS 6: Dissemination according to instructions. 1: the MSS receives a new product 2: the MSS routes the product according to its routing table Routing

  24. 7bis: the user receives the product. FSS New local product available (NC or DCPC WIS function) 5bis: the user obtains the product from the shopping cart. 5: Storage in an online shopping cart or preparation for dissemination: construction of the dissemination instructions. Portal 3: Is someone subscribed to this type of product ? 2: Notification of the product availability DAR subscriptions (user profile) 6: the product and instructions are forwarded OpenWIS 4: the required products are extracted and returned. SOURCE TRANSMET 7: Dissemination according to instructions. Routage 1: New local product
