  10. 10. OpenAgris  OpenAgris is a Web application entirely based on RDF  OpenAgris aggregates information from different data sources to expand the AGRIS knowledge about a topic or a document  OpenAgris is a linked-data environment that mashes-up various interlinked datasets, which will be combined to create meaningful results  Currently, the RDF-ization process has produced nearly 60 million triples  OpenAgris uses the Agrovoc thesaurus as backbone to interlink to other existing datasets (DBPedia, WorldBank, Geopolitical Ontology…)Fabrizio Celli - SKOS-2- 10 johannes keizer
