RDF and OWL are two important Semantic Web technologies.
The Semantic Web
The Semantic Web is a framework for sharing data between companies, applications, enterprises, communities, and people, independent of platform and software.
RDF and OWL are key Semantic Web technologies.
RDF - Resource Description Framework
RDF is a language for describing Web resources, such as the title, author, modification date, content, and copyright information of a Web page.
