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…)
