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.
