OWL

Management Summary

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 an Information content than that supported by other languages like 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.

Dimensions of the language:

Perspective (Role of End user):

Systems

Aspects:

Data/Knowledge

Semantics:

formal (high expressiveness)

Framework:

W3C

Relevance for Use Case:

none

Maturity Level:

established

Semantics:

OWL has a very clear semantics because of its strong relationship to description logics.

Syntax:

Modelling concepts and functionalities, level of formalism, graphical notation
OWL is mainly motivated by a specific branch of logic - description logic, i.e. OWL DL. OWL FULL and OWL LITE are variants in order to improve expressiveness resp. computational performance. Because of its strong relationship to description logics OWL DL has the same operators which can be used to build up your knowledge base by defining terms with the combination of other terms. OWL itself comes in different syntactical formats. The most popular one is the RDF format. OWL is currently under further improvement resulting in OWL 2.0
