The National Agricultural Library's Agricultural Thesaurus(NALT) is now available as Linked Open Data. The NALT, which contains more than 82,000 terms, is primarily used for indexing and for improving the retrieval of agricultural information, including the supporting biological, physical and social sciences. With the NALT's RDF/SKOS files updated with persistent URIs, Web developers can now use the NALT to specify relationships between isolated data silos, making research into agricultural topics more productive.
