OWL is a language for processing web information.
What is OWL?
- OWL stands for Web Ontology Language
- OWL is built on top of RDF
- OWL is for processing information on the web
- OWL was designed to be interpreted by computers
- OWL was not designed for being read by people
- OWL is written in XML
- OWL has three sublanguages
- OWL is a W3C standard
What is Ontology?
Ontology is about the exact description of things and their relationships.For the web, ontology is about the exact description of web information and relationships between web information.
Why OWL?
OWL is a part of the "Semantic Web Vision" - a future where:- Web information has exact meaning
- Web information can be processed by computers
- Computers can integrate information from the web
OWL was Designed for Processing Information
OWL was designed to provide a common way to process the content of web information (instead of displaying it).OWL was designed to be read by computer applications (instead of humans).
OWL is Different from RDF
OWL and RDF are much of the same thing, but OWL is a stronger language with greater machine interpretability than RDF.OWL comes with a larger vocabulary and stronger syntax than RDF.
OWL Sublanguages
OWL has three sublanguages:- OWL Lite
- OWL DL (includes OWL Lite)
- OWL Full (includes OWL DL)
OWL is Written in XML
By using XML, OWL information can easily be exchanged between different types of computers using different types of operating system and application languages.OWL is a Web Standard
OWL became a W3C (World Wide Web Consortium) Recommendation in February 2004.A W3C Recommendation is understood by the industry and the web community as a web standard. A W3C Recommendation is a stable specification developed by a W3C Working Group and reviewed by the W3C Membership.

In computer science and information science, an ontology is a formal representation of knowledge as a set of concepts within a domain, and the relationships between those concepts. It is used to reason about the entities within that domain, and may be used to describe the domain.
In theory, an ontology is a "formal, explicit specification of a shared conceptualisation".[1] An ontology provides a shared vocabulary, which can be used to model a domain — that is, the type of objects and/or concepts that exist, and their properties and relations.[2]
Ontologies are used in artificial intelligence, the Semantic Web, systems engineering, software engineering, biomedical informatics, library science, enterprise bookmarking, and information architecture as a form of knowledge representation about the world or some part of it. The creation of domain ontologies is also fundamental to the definition and use of an enterprise architecture framework.
