Towards a Shared European and National State of the Environment - SoER makes SENSE - LinkedData (RDF) applied to Environment - Antonio De Marinis (EEA)

  1. 1. SoER makes SENSE towards a Shared European and National State of the Environment Antonio De Marinis Click to edit Master subtitle style European Environment Agency eea.europa.eu Technical Workshop 9/26/09 meeting 23 Feb 2010 NRC IS
  2. 2. SOER website
  3. 3. Content provision SENSE Scenario 1 Scenario 2 Scenario 3 I
  4. 4. Manual upload via Plone
  5. 5. SENSE: Automatic content sharing Why SENSE? To automatically fetch, synchronize, publish share national SOER information and data across Europe and even the entire web
  6. 6. How? What data format? RDF/XML
  7. 7. Why RDF/XML? widely accepted open standard from Used for Linked Data and the wider Semantic Web initiatives around the world The Semantic Web provides a common framework that allows data to be shared and reused across application, enterprise, and community boundaries (World Wide Web Consortium - W3C, 2009)
  8. 8. What is RDF/XML? RDF stands for systems as web pages (HTML) stands for humans RDF is a standard framework to describe structured data With RDF it is possible to share and link raw data across the web It enable to browse and query the data, no matter where it is
  9. 9. Simple and powerful data model XML base syntax (RDF is XML) Supports XML schema data types Express statements about any resource Provides formal semantics and provable inference Therefore it supports logic programming and reasoning
  10. 10. Semantic web layercake diagram
  11. 11. What is Linked Data? a term used to describe a recommended best practice for exposing, sharing, and connecting pieces of data, information, and knowledge on the Semantic Web using URIs and RDF."
  12. 12. LinkedData EnvData EnvData EnvData EEA-Eionet Eurostat Country (reportnet) SENSE
  13. 13. Our long term vision create the web of environmental data
  14. 14. RDF Basic concepts
  15. 15. RDF Model Predicate Subject Object (property) sentence: Mr. De Marinis likes Italian wine likes Mr. De Italian Marinis (property) wine
  16. 16. RDF/XML representation 1. <?xml version="1.0"?> 2. <rdf:RDF xmlns:rdf="http://www.w3.org/1999/02/22-rdf-syntax-ns#" 3. xmlns= http://wine.com/ > 4. <rdf:Description rdf:about="http://www.eea.europa.eu/staff/MrDeMarinis"> 5. <likes>Italian wine</likes> 6. </rdf:Description> 7. </rdf:RDF>
  17. 17. RDF applied to SoER C - SENSE -
  18. 18. SoER C: Class diagram
  19. 19. RDF model example SoER sentence: Water bodies located in Norway are in a good environmental condition. Translates into the following RDF graph: location Water Norway bodies condition good
  20. 20. RDF/XML representation 1. <?xml version="1.0"?> 2. <rdf:RDF xmlns:rdf="http://www.w3.org/1999/02/22-rdf-syntax-ns#" 3. xmlns="http://www.eea.europa.eu/soer/1.0# "> 4. <rdf:Description rdf:about="http://www.environment.no/water-bodies"> 5. <location>Norway</location> 6. <condition>good</condition> 7. </rdf:Description> 8. </rdf:RDF>
  21. 21. National Story RDF example
  22. 22. Triples of the data model
  23. 23. Several National Stories Sequentially add all national stories in same RDF feed: <rdf:RDF xml:lang="en" xmlns:rdf="http://www.w3.org/1999/02/22-rdf- syntax-ns#" xmlns="http://www.eea.europa.eu/soer/1.0#"> <NationalStory rdf:about="..."> ... </NationalStory> <NationalStory rdf:about="..."> ... </NationalStory> </rdf:RDF>
  24. 24. SENSE RDF with figures and data 1 2
  25. 25. Figures and data, alternative RDF representation 1. <Figure rdf:about="http://www.environment.no/vannkvalitet_07.gif"> 2. 3. <dataSource rdf:resource="http://www.environment.no/Maps-and- data/Data/?spraak=EN&amp;dsID=AKUTT"/> 4. </Figure> 1 5. <DataFile rdf:about="http://www.environment.no/Maps-and- data/Data/?spraak=EN&amp;dsID=AKUTT"> 6. <fileName>AKUTT</fileName> 7. <dataURL>http://www.environment.no/Maps-and- data/Data/AKUTT/data.xls</dataURL> 2 8. <mediaType>application/excel</mediaType> 9. </DataFile>
  26. 26. Geographical coverage and logic deduction biogeographical regions like Alpine region or Baltic sea. <NationalStory rdf:about="http://www.environment.it/alpine-water-bodies"> <question>What are the state and impacts?</question> <topic>freshwater</topic> <keyMessage>Global climate change poses a grave threat to the alpine 1 hydrological system, altering precipitation, snow-cover patterns and glaciers, with further effects downstream.</keyMessage> <pubDate>2009-05-15</pubDate> <geoCoverage rdf:resource="http://rdfdata.eionet.europa.eu/article17/bioregions/ALP " /> </NationalStory> 2 Why not Italy, France, Austria etc ? The other geographical coverage can be inferred automatically, deduced by semantic (logic) rules. We have linked the bioregions to country regions. The same can be done for NUTS code.
  27. 27. Geographical coverage <geoCoverage rdf:resource="http://rdfdata.eionet.europa.eu/article17/bioregions/ALP " /> Countries: spatial country coverage in Reportnet 1 For trans-boundary assessments: biogeographical regions like Alpine region or Baltic sea. International river basin districts or sub-national regions like NUTS regions 2
  28. 28. Deduction on topic <NationalStory rdf:about="http://www.environment.it/alpine-water-bodies"> <topic>freshwater</topic> </NationalStory> 1 Deduction by Gemet Thesaurus (now in RDF), we get more topics: surface water (BT) flowing water (NT) ice (NT) river water (NT) 2 We gain much more knowledge and power by linking data and applying reasoning.
  29. 29. Conclusions The SENSE principles: shared SOER information How? via semantic web technology The potential of Linked Data and RDF RDF applied on SOER part C Inspiration for future development of the web of environmental data!
