Official repository for Semantic Web for Earth and Environmental Terminology (SWEET) Ontologies. For more information, see https://sweet.jpl.nasa.gov N.B. this Website will soon be transitioned over to https://esipfed.github.io/sweet.

SWEET ontologies are written in the OWL ontology language and are publicly available. SWEET version is highly modular with 6000 concepts in 200 separate ontologies. You can view the entire concept space from an OWL tool such as Protege by reading in sweetAll.owl. Alternatively, these ontologies can be viewed individually.

SWEET consists of nine top-level concepts/ontologies and is considered as a middle-level ontology; most users add a domain-specific ontology using the components defined here to satisfy end user needs.

SWEET is governed by the ESIP Semantic Technologies Committee (STC) meaning that all proposed changes are evaluated by a number of subject matter experts. If you would like to learn more about SWEET, or are interested in joining the community, please join our community mailing list.

Please see the CONTRIBUTING documentation.

Additionally, if you wish to discuss SWEET issues with the STC, please contact us via the WG email list.
