An ontology helps by standardizing concepts expressed by a vocabulary. An example is the term and concept "near". One might want to distinguish something called DC that is near Baltimore and say: If DC is near Baltimore then Baltimore and DC are not connected, and also that if Baltimore is near DC then DC is also near Baltimore. {nid 2JOP}

Even ontologies differ starting with different primitives and making different distinctions. But often simple alignments can be made to bring general and domain ontologies, such as geospatial ones together. An example of inserting some of the previous USGS region ontology into another ontology called SUMO (Suggested Upper Merged Ontology see http://www.ontologyportal.org/) is shown below.

Even ontologies differ starting with different primitives and making different distinctions. Because of this people have developed ontology harmonization and translation mechanisms, a technical topic discussed more at GeospatialOntologies/Ontology_harmonization. But often simple alignments can be made to bring general and domain ontologies, such as geospatial ones together. An example of inserting some of the previous USGS region ontology into another ontology called SUMO (Suggested Upper Merged Ontology see http://www.ontologyportal.org/) is shown below.
