Fig. 2From: The environment ontology in 2016: bridging domains with increased scope, semantic density, and interoperationIllustrative example of ENVO’s representation of a volcanic eruption process. ENVO’s new environmental process branch allows the participants, inputs, and outputs of environmental processes to be represented. These entities may be from ENVO’s content or imported from other ontologies, promoting interoperation and orthogonality. Green borders indicate ENVO classes, blue borders CHEBI classes, and red borders PATO classesBack to article page
