The National Agricultural Library Thesaurus (NALT) Concept Space is a controlled vocabulary of terms related to agricultural, biological, physical and social sciences. NALT is used by the National Agricultural Library (NAL) to annotate peer reviewed journal articles for NAL’s bibliographic citation database, AGRICOLA , PubAg , and Ag Data Commons . The Food Safety Research Information Office (FSRIO) and Agriculture Network Information Center (AgNIC) also use the NALT as the indexing vocabulary for their information systems. In addition, the NALT is used as an aid for locating information at the Agricultural Research Service (ARS) and the Economic Research Service (ERS) web sites and databases.

18-573: A SKOS concept scheme, enables these data mappings. The “NALT For the Machine Age” (N4MA) initiative was launched in June 2020, transforming the thesaurus into a state-of-the-art multischeme “NALT Concept Space” which captures human conceptual knowledge in machine readable form. This data standard is inspired by GACS and expands on the preexisting hierarchical structure of a thesaurus by creating alternative hierarchical arrangements in sub-schemes within
27-697: Is a more granular knowledge base, containing the NALT Core in addition to 48,000 additional agricultural related organisms (taxa), in addition to several thousand less frequently used concepts for a total of 76,933 concepts. There are 11 concept types (Organism, Chemical, Product, Geographical, Topic) which express the most salient features of the concept space. NALT schemes are available for download, as published and maintained by NAL. The Thesaurus and Glossary can be downloaded in three editions of SKOS: RDF-XML, RDF-Ntriples and RDF-Turtle.

36-708: The Library of Congress Subject Headings, CAB Thesaurus, AGROVOC and Wikidata. NALT, along with the two other major agricultural thesauri, AGROVOC and CAB-Thesaurus, make up the Global Agricultural Concept Space (GACS), which was the first known concept space formed in March 2014. NALT has been endorsed by AGNIC, Research Data Alliance Wheat Data Interoperability Group (RDA WDI) and the Alliance on Agricultural Information and Documentation Services (SIDALC). The thesaurus
45-593: The needs of the ARS of the United States Department of Agriculture (USDA). NALT referenced databases such as the AlgaeBase , BioTech life science dictionary, Cambridge dictionary , Index Fungorum , NCBI Taxonomy Database and Integrated Taxonomic Information System in its formation. The thesaurus was rigorously reviewed and tested by ARS scientists and specialists throughout its early developments. The first edition
54-541: The overall hierarchy. The N4MA vision is to use NALT and other semantic innovations to normalize and connect agricultural data, allowing for machine integration and increased automation to manage and advance agricultural research. An alternative hierarchical arrangement has since been created though structural features “NALT Core” and “NALT Full”. The NALT Core is a trim NALT subscheme with 13,791 frequently used agricultural concepts, including 4,396 agriculturally important organisms (taxa) and structural updates. The NALT Full

These URIs are required for NALT concepts to be used as a global metadata reference, enabling aggregation of content so that related content could be located more efficiently. Its knowledge graph,
