14What is the WIS? (WMO Information System) An overarching approach to meet information exchange requirements of all WMO ProgrammesData centric vs communications centric (legacy approach)Aid WMO to avoid data incompatibilities & problems in sharing valuable data across various programmesEnsure interoperability of Information Systems between WMO Programmes and those outside of the WMO community
15What is the WIS? (WMO Information System) WMO Data Representation Systems (DRS) were historically developed with an inward looking approach to meet Member needs for utilization and exchange of informationBeside legacy exchange systems the WIS offers a Data Discovery, Access & Retrieval (DAR) serviceThe WIS DAR will open WMO Member data services and stores up to a wider COIThe WIS DAR will expose data services and stores of the wider COI across the community
16WIS Standards WMO has been developing DRSs for many decades Work precedes ISO and many other standards bodiesOver 50 legacy DRSTremendous “richness” of capability already existsWMO has captured this “richness” in its Binary Uniform Format for Representation (BUFR)
17WIS DRM BUFR was developed with an inherent data model From this data model all other DRS needs will be drivenISO compatible feature cataloguesLegacy formatsOASIS, OGC, JMBL other requirements
18ISO 19000 Modelling process for BUFR Full BUFR Model BUFR is too big to be represented in a single ISO Feature Catalogue, which should be small enough to be useable by external communities.No external community uses the full BUFR model, and most communities use a small subset, augmented with extractions, aggregations, and compounds of this subset.The ISO model is intended for this sort of use.Full BUFR ModelAviationFeatureCataloguePublicWeather ServiceHydrologicalFeature CatalogueOtherCatalogues?WeatherServiceHydrologyOther NeedsAviation Feature CatalogueAviation community names linked to(one or more) BUFR table elementsHydrological Feature CatalogueHydrological community names and common aliasesPublic Weather ServiceFeature CatalogueCommon names, aliases and language variants linked to relevant BUFR table elements
19WIS DRS DevelopmentWMO Expert Teams are tasked with working directly on DRS standards in the following areasMaintenance and update of existing DRS including BUFRDeveloping and maintaining WMO metadata standards and improving interoperabilityMigrating off legacy systems to new standardsAddressing the DRS requirements of aviation meteorological needsAssessing all DRS requirements of the wider WMO COI and developing policy recommendations regarding how to meet those needs.
20ICAO-WMO PILOT PROJECT FOR REPRESENTING OPMET DATA OPMET data delivery via XML proof of concept - Representation and exchange of TAC OPMET data in XML, initially by wrapping the TAC data in XML and demonstrating the ability to exchange this data over aeronautical telecommunication systems. This phase also includes parsing the contents of the TAC OPMET data into XML and exchanging them as well;Direct conversion of BUFR OPMET data into XML;Development of an ISO compliant modeling process from which feature catalogues are derived. These will include OPMET data in XML/GML as an application of the ISO series of standards.Support for conjoint development of future versions of WXCM, WXXM, WXXS Weather Information Models and Schema
21WIS Data DictionaryThe WIS Data Dictionary is a conjoin of definitions from:BUFRWMO Core Metadata ProfileServices metadataBUFR as the parent data model is the primary componentBUFR contains:Over 450 Code tablesOver 370 flag tablesOver 7,000 total features, elements, codes and flags
22WIS Tie in to Other Standards WMO identified Common Alerting Protocol (CAP), OASIS, as a standard for dissemination of warning messagesDevelopment underway through MembersWMO hosted a CAP Implementers Workshop December 9-10, 2008 in GenevaWMO is assessing Geographic Information Systems (GIS) such as those based on OGC standardsWorkshop on the use of GIS systems was held at the European Centre for Medium Range Weather Forecasting (ECMWF) in Reading, UK from November 2006This workshop reviewed the use of OGC standards to promote collaboration to define a set of common standards to enhance interoperabilityWMO and ISO have developed an agreement on recognition of each other’s standards and are developing the administrative protocols
23WIS Tie in to Other Standards The WMO is continuing to assess other DRS standards some of which are already in use in the COINetwork Common Data Form (NetCDF) ,University Corporation for Atmospheric Research (UCAR)Hierarchical Data Format (HDF), National Center for Supercomputing Applications (NCSA)eXtensible Markup Language (XML), World Wide Web Consortium (W3C) (CAP is based on XML)Abstract Syntax Notation One (ANS.1), joint ISO/IEC and ITU-TJoint METOC Broker Language (JMBL), DoDUsage recommendations are underwaySemantic interoperability being pursued with DRS “owners”Syntactic interoperability being reviewed for development where needed
24Summary - WIS DRM based on: Full BUFRModelServices MetadataBUFR TableDescriptorsWMO Core Metadata ProfileAviationOther Needs?HydrologyOtherCatalogues?PublicWeatherServiceWISDataDictionaryDAS is the official steward for two DRM FrameworksThe FEA DRM provides a framework of three key concepts to assist agencies and communities in their information sharing objectives.Beginning with “How do I find the data and access it” – agencies and communities are encouraged to categorize and publish their information available for sharing. They can publish on their own web site or use core.gov. This allows other agencies to discover potential sharing opportunities.AviationFeatureCatalogueHydrologicalFeature CataloguePublicWeather ServiceFeatureCatalogueWMO Commission for Basic Systems (CBS) is the official steward for these standards
25What are the advantages ISO models are derived from the BUFR modelThe maintenance process is fundamental and is not changedReferences to BUFR entries from Feature Catalogues are invertible.Relevant changes to the BUFR model can be mapped and notified to the user communitiesThe structure allows an automatic mapping from BUFR to XML/GMLNot necessarily the implementation (although likely to be possible using XML tools)The structure allows servicing of data requests which include extraction of data subsets across sets of BUFR data.e.g. query for all air temperatures within a space and time window.All surface BUFR bulletins expanded into BUFR XMLAll mappings of air temperature to BUFR elements selected (with relevant position and times)The data returned in an XML/GML encoding under WFS.
27Discovery Access and Retrieval (DAR) Because DAR metadata must be homogeneous in form and in content, ISO and ISO 19139 are used for the description of discovery metadata.Metadata could be:Sent as a metadata file via WIS to a GISC prior to publishing the data or product,Collected from the data / product producer (batch mode),Manually edited and validated via a web based interface provided by the system,Automatically generated from existing reference catalogues,Possibly built on the fly during the data ingestion.
28Example: Standardized Interface - Information Search and Retrieval (ISO 23950) Standard used by libraries worldwide for searching online catalogs, and it also used for searching geospatial metadata.Defines how to specify searches precisely for accurate results. Includes lat & long boundaries and scientific terms, as well as bibliographic citations.Can be used simply with Internet search engines. But has the expressive power for complex data searches like chemical formulas and pattern-matching needed for images.
31Summarye_ver1_1_UML_ pdfWMO has a long history of DRS developmentWMO is committed to interoperability with the wider COI at semantic and syntactic levelsWMO will leverage its existing data model (BUFR) including an extensive data dictionary to implement ISO, OGC, OASIS and other standards as needed to support requirementsWMO & the NWS is interested in continuing standards development opportunities and relationships with other agencies
