  1. Management of Environmental Information in the European Information and Observation Network (EIONET) Thom Pick, European Topic Centre on Catalogue of Data Sources, Hannover Hannu Saarenmaa, European Environment Agency, Copenhagen Kirsti Lounamaa, TietoEnator, Helsinki presented by Matthias Menger European Topic Centre on Catalogue of Data Sources, Hannover/Germany matthias.menger@numis.niedersachsen.de

  2. The Agency... The European Environment Agency (EEA)

  3. EIONET The European Environment Information and Observation Network (EIONET)

  4. OECD UNEP EU Coordination Coordination Eurostat Spatial levels Coordination National Data Providers National Data Providers EEA National Data Providers EIONET ReportingSytem ETC ETC European Level Other EEA Coordination NFP National Data Providers ETC ETC National Level NFP NRC NRC NRC NRC NRC NRC NRC NRC A Network of Networks

  5. The Public and Decision-Makers EC EEA OECD UNEP Other Eurostat DG DG ETC DG DG National Env Centres NFP and other National Authorities Current Situation

  6. The Public and Decision-Makers Eurostat EC EEA OECD UNEP Other DG ETC DG REPORTNET NRC NFP and other National Authorities Target Situation

  7. ReportNet

  8. Directory Manage information on persons, organisations, roles, and contact details

  9. Repository Place for deliveries of data, information, and knowledge to the international reporting system

  10. Content Registry Keeps track of the deliveries of data sets to the international reporting system, and other content.

  11. Content Registry - Basic Concept Content registry refere to Data harvest metadata Descriptions RDF, DCES Metadata Repositories Data

  12. Content Registry- Basic Concept Transfer of metadata from services (repository) to CR • Put it into RDF, send to CR when requested • RDF generated on the fly • RDF pre-saved • (Scenario for most of the services) • Send it as objects via SOAP calls • requires an API wrapper at the service side • (Scenario for CIRCA)

  13. Content Registry- Basic Concept Metadata transfer with RDF <?xml version="1.0" encoding="iso-8859-1" ?> <rdf:RDF xmlns:rdf="http://www.w3.org/1999/02/22-rdf-syntax-ns#" xmlns:dc="http://purl.org/dc/elements/1.1/"> <rdf:Description rdf:about="http://eea.eu.int/sdrat4"> <dc:creator>Jensen</dc:creator> <dc:title>Signals 2002</dc:title> <dc:language>English</dc:language> <dc:type>Report</dc:type> <dc:coverage>EU</dc:coverage> <dc:relation> follow up of Signals 2001 <eionet:rod-id>78890</eionet:rod-id> </dc:relation> </rdf:Description> </rdf:RDF> Store into CR-DB . . . . . . . . . Store RDF into file system

  14. Data Dictionary Element:Longitude <xsd:element name="longitude"><xsd:annotation><xsd:documentation xml:lang="en">The measure of the angular distance on a meridian east or west of the prime meridian. +/-DDD.dd to +/-DDD.dddddd where D=degree, d=decimal degree, + = East and - = West of the prime meridian. A point on the prime meridian is Eastern Hemisphere; the 180th meridian is Western.</xsd:documentation></xsd:annotation><xsd:complexType><xsd:simpleContent><xsd:restriction base="xsd:decimal"><xsd:minLength value="7"/><xsd:maxLength value="11"/><xsd:pattern value=“[\+\-]\d{3}\.\d{2,6}"/><xsd:maxExclusive value="180.00"/><xsd:minInclusive value="-180.00"/></xsd:restriction></xsd:simpleContent></xsd:complexType></xsd:element> Aggregate:Station <xsd:element name="station"><xsd:complexType><xsd:sequence><xsd:element name=“stationSize“> ……. </xsd:element><xsd:element name=“stationType"> ……. </xsd:element><xsd:element name=“stationLongitude" ref="longitude"/></xsd:sequence></xsd:complexType></xsd:element> • Registry for other applications and projects to refer to and share data definitions • Stores definitions of data elements, their details and status.Browse, search, import, export functions

  15. Obligations Descriptions of the needs of data and information

  16. Dependencies of ReportNet components National data- bases and systems Public web services DEM Data Dictio- nary Search Content Registry Reposi- tory Na- Mod Indi- cators Obliga- tions Direc- tory

  17. System Architecture Java Runtime Environment HTTP Server WWW Browser Browsing, searching & modifying logic HTTP HTML XML User Interface shell SOAP • Applications • data • exchange • modules • data • warehouses • CIRCA • ... Database Handling Business logic Content Registry JDBC Import / Export logic RDF repository

  18. Multilingual Aspect - GEMET • metainformation contain keywords of the • General Multilingual Environmental Thesaurus • consists of ~5400 terms • translated into 19 European languages • polyhierarchical • includes synonyms • ‘sorted’ by environmental themes • GEMET is used also for discovery

  19. GILS CDS GELOS Dublin Core Mapping GELOS against DC

  20. Bridges

  21. Swedish Environet • Swedish EnviroNet: DCES with its own extensions (DCQ)

  22. DC and Environmental Information • Environmental information resources become increasingly available through the internet. • EIONET is adopting DCES for description and discovery of its information resources by: • extending DCES and DCQ with the ‘missing’ elements and qualifiers, while fitting them with their domain specific themes and • defining an individual namespace for each data element. • ReportNet is the approach to integrate services based on DC.

  23. The End... matthias.menger@numis.niedersachsen.de ...is just the beginning thom.pick@numis.niedersachsen.de

  24. DC: Environment InterestGroup The Idea for such open forum might be: • to collect information on usage of DC in the environmental domain, • to give guidance of the use of DC in the environmental domain, • to install a forum for discussion of issues concerning DC with respect to environmental information resources, • to develop an application profile for the environmental domain, based on DC • to establish the representation of the environmental domain and their issues in DCMI (and vice versa?) ...

  25. DC:Environment InterestGroup • ... • to promote interoperability within the environmental domain through the use of dublin core • to liaise with other communities in the environmental domain that do not use DC for their resources • explore the possibilities to set up a DCMI Working Group for Environment matthias.menger@numis.niedersachsen.de thom.pick@numis.niedersachsen.de
