LOD2 Webinar: The 2nd release of the LOD2 stack

991

Published on

This webinar in the course of the LOD2 webinar series will present the release 2.0 of the LOD2 stack, which contains updates to the components Ontowiki, Silk

* the assisting sparql editor SPARQLED (DERI),
* the LOD enabled Open Refine (previously Google Refine) (ZEMANTA),
* the extended version of SILK with link suggestion management from LATC (DERI),
* the rdfAuthor library which allows to manage structured information from RDFa-enhanced websites (ULEI),
* the SPARQLPROXY which is a PHP based forward proxy for remote access to SPARQL end points (ULEI)

Release 2.0 contains also a first contributed debian package for a component which is maintained by a group outside the LOD2 consortium. With the help of ULEI a package for the STANBOL engine (http://stanbol.apache.org/) has been contributed.

If you are interested in Linked (Open) Data principles and mechanisms, LOD tools & services and concrete use cases that can be realised using LOD then join us in the free LOD2 webinar series!

LOD2 Webinar: The 2nd release of the LOD2 stack

  1. 1. LOD2 is a large-scale integrating project co-funded by the EuropeanCommission within the FP7 Information and Communication TechnologiesWork Programme. This 4-year project comprises leading Linked OpenData technology researchers, companies, and service providers. Comingfrom across 12 countries the partners are coordinated by the AgileKnowledge Engineering and Semantic Web Research Group at theUniversity of Leipzig, Germany.LOD2 will integrate and syndicate Linked Data with existing large-scaleapplications. The project shows the benefits in the scenarios of Media andPublishing, Corporate Data intranets and eGovernment.
  2. 2. Once per month the LOD2 webinar series offer a free webinar abouttools and services along the Linked Open Data Life Cycle.Stay with us and learn more about acquisition, editing, composing,connected applications – and finally publishing Linked Open Data.

  10. 10. LOD2 stack prerequisites & support• The component providers are responsible for the Debian package – the knowledge and experience with packaging increases – Improves the overall quality of the individual components• The LOD2 stack standardizes on Ubuntu 12.04 LTS, Precise edition – Other Linux distributions are in principle possible – Our partner I2G, Poland, successfully installed a version on Debian• Requires 2GB RAM, better at least 4GB – Many components are tomcat based web-apps – Footprint can be reduced by only installing the needed applications for your case• Technical feedback on the stack via support-stack@lod2.eu
  11. 11. Demo Scenario• Linked Data has the ability to merge and enrich your data.• Show that with a few steps this promise comes close to reality.

  15. 15. More inter component integration• The consortium’s goal is higher inter component integration – Smoothen information flow between components 2012 2012• It is a challenge! – Integration in a general context does not lead to high end-user satisfaction• Focus on one domain – Create supportive end-user process flows for this case – They will be described and very likely many of them are applicable for other domains.
  16. 16. The Statistical OfficeSelected because …• many partners deal with statistical data in their projects – The LOD2 consortium is involved in all key aspects: • standarization of the schema (DataCube) • publishing statistical data (e.g. http://eurostat.linked-statistics.org, http://scoreboard.lod2.eu, http://rs.ckan.net/dataset?q=rdf ) • Tools (e.g. Cubeviz)• real world statistical data is accessible for experimentation• it offers excellent potential to combine components from LOD2 stack• the data integration capabilities of RDF can be exploited• the Linked Data paradigm is an enabler to go beyond classical statistics management
