Help:Ontology

Ontologies are used to capture knowledge about some domain of interest. An ontology describes the concepts in the domain and also the relationships that hold between those concepts.

• Components of OWL Ontologies
  • IDIVIDUALS: represent objects in the domain in which we are interested.
  • PROPERTIES: are binary relations on individuals - i.e. properties link two individuals together. For example, the property "Has historical geographical allegiances" might link the tune "Craig a' Bhodich" to the tune "Fisher's Hornpipe", or the property "Is also known as" might link the tune "Fisher's Hornpipe" to the tune "Crannciuil Ui Fishuir". Properties can have inverses. For example, the inverse of hasOwner is isOwnedBy. Properties can be limited to having a single value, i.e. to being functional. They can also be either transitive or symmetric.
