The document discusses the role of AGROVOC, an open linked vocabulary developed by the Food and Agriculture Organization (FAO) of the United Nations. It describes FAO's goal of making agricultural knowledge available globally and highlights key dynamics shaping information aggregation and distribution. It then demonstrates FAO's initiatives to link diverse data sources and develop applications like OpenAGRIS using AGROVOC as the backbone vocabulary to integrate information on topics like rural populations, cereal yields and fisheries. FAO is working to realize a vision of seamless access and sharing of agricultural data through linked open vocabularies and technologies.

to those who need it when
they need it and in a form
which they can access and

14. Faceet 3: working together

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.

19. 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…)
