  • 5. Creating Knowledge out of Interlinked DataIntegration Objectives1. Improve the overall software support for Linked Data publication.2. Support deployment Linked Data components3. Improve information sharing between Linked Data components so that publishing Linked Data is eased.4. Improve access to the content: the online Linked Open Data.EU-FP7 LOD2 WP6 – 21.-23.3.2012.

  • 7. Creating Knowledge out of Interlinked DataSome year 1 review comments• Page 2: Something that requires particular attention during the second year is how the different technologies developed in the project complement one another to address the current limitations of the LOD web.• Page 3: How do the developments in Virtuoso, taking place in this project, address these problems? And how will those developments allow SILK or SIG.MA, for instance,to work better?• The SOA and the requirements analysis do not cover some issues related to querying multiple datasets in combination. An example for such question could be: Do people want to be able to do queries like the following one: SELECT ?band ?location WHERE { ?band music-ont:similar_to dbpedia:Dire_Straits; dbp-ont:hometown ?location . ?location geo-ont:parentFeature dbpedia:Germany. } If it was possible to define and evaluate such queries efficiently, can one expect LOD data to be used more widely? Note that such query requires owl:sameAs semantics to be applied to aggregate data from MusicBrainz, DBPedia and Geonames and the transitivity of location nesting relation of Geonames to be enforced.EU-FP7 LOD2 WP6 – 21.-23.3.2012.

  • 8. Creating Knowledge out of Interlinked DataWP6: past 6M – Core workMaintenance of the LOD2 stack • Improving existing tools • Adding new tools • Infrastructure management (repository, online demo, ...) • Improving lod2 demonstratorDissimination of the LOD2 stack • LOD2 stack Webinars • Wiki.lod2.eu: documentation wiki • Stack.lod2.eu / lod2.eu website • Integrating new LOD2 partners • Legal aspects => IPR documentTesting activities • Automatic test (test.stack.lod2.eu) • Application scenarios study • Overview of testing activities for each components • Overview of hardware requirementsEU-FP7 LOD2 WP6 – 21.-23.3.2012. Page 8 http://lod2.eu
  • 9. Creating Knowledge out of Interlinked DataWP6: Past 6M: Integration workShared user interfaces • Shared graph management • Shared prefix management • Shared vocabulary management • Goal: create webapi’s that support these functionalities & have them used by some toolsShared Authentication • WebID has been chosen as authentication mechanism for the LOD2 stack • Goal: a single sign on mechanism for all Tomcat based componentsShared Provenance • First meetings just past • Goal: a vision document to be elaborated Y3EU-FP7 LOD2 WP6 – 21.-23.3.2012.

  • 10. Creating Knowledge out of Interlinked DataWP6: an intermediate milestone achievedIntermediate release 1.1 of the LOD2 stack: 12 march 2012• New tools: • Limes & colanut • Valiant • Semantic Spatial browser• Upgraded tools (w.r.t. sept. 2011) • Virtuoso • Ontowiki • Silk• Documentation & IPR documentEU-FP7 LOD2 WP6 – 21.-23.3.2012.

  • 11. Creating Knowledge out of Interlinked DataWP6: Core: next 6MMaintenance of the LOD2 stack • Standarize on Ubuntu 12.04 LTS for the next 2,5 years • Smooth release management => ensuring that all is right => Quality enhancement • Many new tools are get available • Smooth searching and publishing in CKAN repositoriesDissimination of the LOD2 stack • Webinars continueTesting activities • Multi stage repository • test server activation • First evaluation w.r.t. Application scenariosEU-FP7 LOD2 WP6 – 21.-23.3.2012. Page 11 http://lod2.eu
  • 12. Creating Knowledge out of Interlinked DataWP6 breakout discussion topicsYear 2 finalisation • Planning alignment • Deliverable documents descriptionIntegration (Do we work towards answering the right questions?) • When does a component is a true member of the LOD2 stack? • Demonstrator vs Configurator • Intercomponent feedback loops • Shared user interface experience • Authentication & provenance (only feedback probably)Application scenarios & evaluating the LOD2 stackCollaboration with other EU projects: e.g. LarkCEU-FP7 LOD2 WP6 – 21.-23.3.2012.
