RDF and OWL are two important Semantic Web technologies.
RDF and OWL are two important Semantic Web technologies.
Semantic Web
The Semantic Web is a framework for asset management, enterprise integration, and sharing and reuse of network data.
The Semantic Web provides a platform- and software-independent framework for data sharing among enterprises, applications, companies, groups and individuals.
RDF and OWL are key technologies of the Semantic Web. They respectively elaborate on structural descriptions and World Wide Web-based ontologies.
RDF - Resource Description Framework
RDF is a language for expressing information on the World Wide Web.
RDF can be used to describe web resources, such as title, author and version information, content description, availability schedule, etc.

OWL - Web Ontology Language
OWL is a language used to define ontologies.
Ontology can describe the domain of knowledge. Can be used by humans or software to share information about objects, which can be cars, houses, machines, books, products, financial transactions, and more.
OWL is designed for processing information (not real-world information).

SPARQL - Query language for RDF
SPARQL is a standard query language for RDF data, providing developers with a way to write queries that span wide areas of RDF information on the WEB.
