  • in OWL Lite classes can only be  defined in terms of named superclasses (superclasses cannot  be arbitrary expressions), and only certain kinds of class  restrictions can be used.

  • OWL  facilitates greater machine interpretability of Web content  than that supported by XML, RDF, and RDF Schema (RDF-S) by  providing additional vocabulary along with a formal  semantics.
  • OWL can be used to explicitly represent the meaning  of terms in vocabularies and the relationships between those  terms.
  • OWL is a revision of the    DAML+OIL web ontology language incorporating lessons  learned from the design and application of DAML+OIL.
  • 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 completeness (all  conclusions are guaranteed to be computable) and  decidability (all computations will finish in finite  time).
  • OWL  Full is meant for users who want maximum  expressiveness and the syntactic freedom of RDF with no  computational guarantees.
  • OWL Full can be viewed as an extension of RDF, while OWL  Lite and OWL DL can be viewed as extensions of a restricted  view of RDF.
  • some care has to be taken when a  user wants to migrate an RDF document to OWL
  • The range of a property limits the  individuals that the property may have as its value
  • For example, the  property hasChild may be stated to have the range of  Mammal. From this a reasoner can deduce that if Louise is  related to Deborah by the hasChild property, (i.e., Deborah  is the child of Louise), then Deborah is a Mammal.
  • FunctionalProperty : Properties may be stated  to have a unique value. If a property is a  FunctionalProperty, then it has no more than one value for  each individual (it may have no values for an individual).
  • ObjectProperties are relations between instances of two  classes.
  • DatatypeProperties are relations between instances of classes  and RDF literals and XML Schema datatypes

  OWL Features and RDF vocabularies

  • OWL Full can be viewed as an extension of RDF, while OWL  Lite and OWL DL can be viewed as extensions of a restricted  view of RDF
  • Every OWL (Lite, DL, Full) document is an RDF  document, and every RDF document is an OWL Full document, but  only some RDF documents will be a legal OWL Lite or OWL DL  document

  The OWL Web Ontology Language is designed for use by applications that need to process the content of information instead of just presenting information to humans.

  The OWL Web Ontology Language is designed for use by applications that need to process the content of information instead of just presenting information to humans. OWL facilitates greater machine interpretability of Web content than that supported by XML, RDF, and RDF Schema (RDF-S) by providing additional vocabulary along with a formal semantics. OWL has three increasingly-expressive sublanguages: OWL Lite, OWL DL, and OWL Full.

  OWL has been designed to meet this need for a Web Ontology Language. OWL is part of the growing stack of W3C recommendations related to the Semantic Web.
