AB: The Semantic Web for Earth and Environmental Terminology (SWEET) provides a set of upper-level ontologies constituting a concept space of Earth system science. These ontologies can be used, mapped, or extended by developers of specialized domain ontologies. SWEET components are being adopted within a diverse range of applications, including: the Geosciences Network (GEON), the Marine Metadata Initiative (MMI), the Virtual Solar Terrestrial Observatory (VSTO), and the Earth Science Markup Language (ESML). SWEET includes 12 ontologies, decomposed into component parts that can be reassembled to meet the needs of user communities. For example, the Property ontology terms (e.g., temperature, pressure) can be associated with measurable (observable) quantities of a dataset. The Substance ontology provides representations of the substance in which a property is being measured (e.g., air, water, rock). The Earth Realm ontology provides representations for the environmental regions of the Earth (e.g., atmospheric boundary layer, ocean mixed layer). The Data and Service ontology enables representations of how data are captured, stored, and accessed. The Numerics ontology entries represent 2-D and 3-D objects or spatial/temporal entities and relations. The Human Activities ontology captures the human side or applications of Earth science. The Phenomena ontology describes major geophysical or geophysical-related events. All of the ontologies are written in the OWL-DL language to give domain specialists a starting vocabulary, over which layers, synonyms, or extensions can be applied.
