LOD2 Webinar Series: OntoWiki

Creating Knowledge out of Interlinked Data

LOD2 Presentation . 02.09.2010 . Page http://lod2.eu





LOD2 is a large-scale integrating project co-funded by the European Commission within the FP7 Information and Communication Technologies Work Programme. This 4-year project comprises leading Linked Open Data technology researchers, companies, and service providers. Coming from across 12 countries the partners are coordinated by the Agile Knowledge Engineering and Semantic Web Research Group at the University of Leipzig, Germany.

LOD2 will integrate and syndicate Linked Data with existing large-scale applications. The project shows the benefits in the scenarios of Media and Publishing, Corporate Data intranets and eGovernment.




Once per month the LOD2 webinar series offer a free webinar about tools 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.
