How can I get in real time all the specimen data on useful insects from all people making research on this on my desktop? How can I share in real time my data with other colleagues working on that.
Faceet 3: working together

Our First Demonstrator: 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…)
