public class Ontology
extends Object

Ontology : An ontology formally represents knowledge as a set of concepts within a domain, and the relationships between those concepts. It can be used to reason about the entities within that domain and may be used to describe the domain. An Ontology at present used in SMILE model is to resolve the ambiguity related to the units in the model.Ontology used in the model is the OM ontology of Unit of Measure. An Ontology of units of Measure and related concepts (OM) models concepts and relations important to scientific research. It has a strong focus on units and quantities, measurements, and dimensions. The home page of the OM ontology is: http://www.wurvoc.org/vocabularies/om-1.8/
