Ontology Languages: The ontology languages are created to describe the classes and relations between them also to add properties and attributes in web documents and application.

During last few years many ontology languages have been developed. XOL (Ontology Exchange language) is based on XML syntax. The other XML based languages are SHOE (which was previously based on HTML) and Ontology markup Language OML.

RDF (Resource description framework) and RDF schema are languages by worldwide consortium (W3C) working groups. The union of RDF and RDF schema are developed to build on the top of RDF to improve features of RDF.

What is OWL? OWL is a web ontology language. It is a group of markup languages that are designed to process the information. OWL ontology describes the hierarchical ideas in a domain. OWL helps to represent the knowledge so that software as well as human can understand it. OWL can express the knowledge or meaningful information better than XML, RDF-S. OWL has lots of facilities for knowledge representation. OWL provides lots of facilities for describing properties and classes; relationships between classes for example disjoint classes, cardinality, equality, meaningful properties, characteristics of properties and enumerated classes. The new group of W3C worked to extend OWL with several new features. This new version called OWL 2.0. This version got added to semantic editors such as Protégé and semantic reasoners such as “Pellets”, ”RacerPro” and “Fact ++”.OWL is divided into three different languages. OWL LIGHT, OWL DL, OWL FULL.
