OWL (Web Ontology Language) and RDF (Resource Description Framework) are the two standards that govern the construction and processing of ontologies. Ontologies are used to provide an understanding of the structure of information through modeling; It is an alternative to viewing source code. Ontologies are made up of two main components: classes and relationships. These two components are what form Triples by connecting the relationship between two classes. Below is an example of a Triple:
RDF was build on top of XML in order to give meaning to the content XML tags. XML did not. RDF implements the idea of triples to create vocabularies. These vocabularies can be referenced via URI's that identify the desired properties. OWL is an extension of RDF that has three sub-languages: OWL Lite, OWL DL, and OWL Full. In their respective order, each language gets more extensive. Both OWL and RDF are written in XML, but what makes OWL different is that it is better interpreted by computers through it's larger vocabulary and stronger syntax. The purpose of OWL is to create web web ontologies to create a "web of data" by making the web's textual content readable by machines. Dr. Bansal has advised us of an open source application that is used to create web-ontologies using the OWL language.
