Ontology Web Language(OWL)

OWL is derived from DAML+OIL which is a language for expressing classifications and properties of resources. OWL adds more vocabulary for describing properties and classes. OWL is used to represent the meaning of terms in vocabularies and the relationships between those terms. OWL is divided onto three sub-language which is:

  • OWL Lite
  • OWL DL
  • OWL Full
OWL Lite supports those users primarily needing a classification hierarchy and simple constraints.
OWL DL supports those users who want the maximum expressiveness while retaining computational
OWL Full meant for users who want maximum expressiveness and the syntactic freedom of RDF with no computational guarantees.
