Agropedia has created a range of knowledge models, representing information through structured data. The FAO also have a substantial thesaurus of terms (AGROVOC) used for managing information across contexts and languages. Such structured models can be used to aid retrieval of information - and become even more useful when datasets share the same terms, either by using the same linked data URIs to identify each term, or by mapping between terms.

The availability of an infrastructure of terms and definitions for linking against in RDF (the main linked data format) has implications for how a development linked data web will development. Zoom in and explore the knowledge model below.
