LOD Best practise: reegle.info and OpenEI

  1. 1. Sharing datasets to enrich key energy portals Florian Bauer (REEEP) & Jon Weers(NREL)
  2. 2. (a typical website)  Stores all information in its own database  Other sites have similar design pattern => Duplication of effort and information  Both sites responsible for updating information => Potential for online community to be presented with conflicting information 2
  3. 3.  Datasets are shared behind the scenes => Each site can focus on key data and import supplemental data Imported data updates automatically => Provides users with consistent information across multiple sites Other Websites can consume LOD resources to present new content in exciting and unanticipated ways 3
  4. 4. Linking Open Data cloud diagram, by Richard Cyganiak andAnja Jentzsch. http://lod-cloud.net/ 4
  5. 5. http://www.reegle.info Well established information gateway for high quality information on renewable energy, efficiency and climate compatible development More than 220,000 users per month New data portal data.reegle.info launched in 2011Available as Linked Open Data:  key datasets including energy statistics  over 1,700 stakeholders worldwide  extensive glossary enriched with DBpedia linked data  country energy profiles including policy & regulation data
  6. 6. http://en.openei.org OpenEI is a collaborative knowledge-sharing platform with free and open access to energy-related data, models, tools, and information. OpenEI features: more than 55,000 content pages more than 600 downloadable datasets regional gateways on a variety of energy-related topics numerous online tools, including country pages.. 6
  7. 7. reegle / OpenEI cooperation … … an exampleOne of the featured pieces of content on OpenEI’s country pages isthe reegle Policy and Regulatory Overview: 7
  8. 8. reegle / OpenEI cooperation …Behind the scenes, Linked Open Data at Work:  reegle profiles are consumed in real time directly from the reegle database using SPARQL  use of semantic concepts allows the correct profile to be pulled 8
  9. 9. Advantages of Linked Open DataFocused Efforts• The authors of a website can display all relevant information about a topic but focus on providing only the information they are subject matter experts ofAvoids Replication• Re-using existing datasets avoids replication of work already doneReduced Maintenance and Effort• Updates to linked open data are propagated instantly• Maintenance costs and development efforts of larger datasets can be distributed among contributing partnersSemantic Linkages and Interoperability• Concepts become part of the semantic web• Data mash-ups and utilizations never before imaged 9
