OWL, known as Web Ontology Language, is a network ontology language developed by W3C to semanticly describe the ontology.
OWL is a language for processing web information.
Before you learn OWL, you should have a basic understanding of XML, XML namespaces, and RDF.
If you are learning about these projects first, please visit:
XML and RDF tutorials for W3Cschool.
The term "ontology" comes from philosophy, which is the study of the various entities of the world and how they are related to science.
For web, the ont body provides an accurate description of the relationship between web information and web information.
OWL is part of the Semantic Web Vision - the objectives are:
OWL is designed to provide a common way to handle the content of Web information (rather than showing it).
OWL is designed to be read by computer applications (not by humans).
OWL has many similarities to RDF, but OWL is a more powerful language with greater machine interpretation capabilities than RDF.
OWL has a larger vocabulary and a more powerful language than RDF.
OWL has three sub-languages:
By using XML, OWL information can be exchanged between different types of computers that use different types of operating systems and application languages.
OWL became a W3C recommendation in February 2004.
W3C recommendations (standards) are presented as web standards by the industry and the web community. The W3C recommendation is a stable specification developed by the W3C Working Group and reviewed by W3C members.
