General ontology resources available:

  • ATCC: American Type Culture Collection. Collections and Repository:All collections.

  • CABRI: Common Access to Biological Resources and Information. Data input & authentication.

  • ChemIDplus: A database of 350,000 chemical records, including over 100,000 with structures. Locator links allow immediate searching of other databases for information about a given chemical.

  • Gramene plant trait ontology.

  • HistoBank: The interactive histology atlas. (covers human, mouse, rat)

  • ILAR: The Institute for Laboratory Animal Research. Animal Models and Genetic Stocks Information Program.

  • LOINC:The purpose of the LOINC database is to facilitate the exchange and pooling of results, such as blood hemoglobin, serum potassium, or vital signs, for clinical care, outcomes management, and research.

  • Medical Subject Headings (MeSH): The Medical Subject Headings comprise NLM's controlled vocabulary used for indexing articles, for cataloging books and other holdings, and for searching MeSH-indexed databases, including MEDLINE. MeSH terminology provides a consistent way to retrieve information that may use different terminology for the same concepts. MeSH is a principal component vocabulary of the Unified Medical Language System (UMLS®). [listed below]

  • Medline: The SRS site which provides the data fields in Medline including Publication Type.

  • MGED Ontology: The MGED Ontology describes microarray experiments and the samples used in them. In addition to the ontology itself a list of web based ontology resources and descriptions is maintained at the site.

  • OBO (formly GOBO - Global open biological ontologies): The Global Open Biology Ontologies (OBO; http://obo.sourceforge.net) project supports the development of structured shared controlled vocabularies and ontologies for use within the genomics and proteomics domains. There are five criteria for inclusion in OBO: openness, sharable syntax (such as the GO syntax or DAML+OIL), orthogonality to other GOBO ontologies, shared ID space, and term definitions.

  • Taxonomy Browser: The NCBI Taxonomy Homepage.

  • Unified Medical Language System (UMLS): NLM's Unified Medical Language System (UMLS) project develops and distributes multi-purpose, electronic "Knowledge Sources" and associated lexical programs. System developers can use the UMLS products to enhance their applications -- in systems focused on patient data, digital libraries, Web and bibliographic retrieval, natural language processing, and decision support. Researchers will find the UMLS products useful in investigating knowledge representation and retrieval questions.
