Linked Data
Linked Data is a method of web publication in which each individual piece of data is:
- uniquely identified using HTTP URIs (that is, URLs, or 'web addresses'),
- available both as 'machine readable' data and as 'human readable pages, and
- linked to other resources.
AGROVOC is available as a Linked Open Data (LOD) set published, aligned (linked) with several vocabularies. The LOD version of AGROVOC is in RDF/SKOS-XL, and is stored in Apache Jena Fuseki (data is accessible to machines through a SPARQL endpoint, and to humans by means of HTML pages generated with Loddy).
