W3C RDF and OWL Activities


RDF and OWL are two important Semantic Web technologies.


Semantic Web

The Semantic Web provides a framework for asset management, enterprise integration, and the sharing and reuse of data across networks.

The Semantic Web provides a platform-independent 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 describe structural descriptions and ontology based on the World Wide Web.


RDF - Resource Description Framework

RDF is a language for expressing information about resources on the World Wide Web.

RDF can be used to describe web resources, such as title, author, version information, content description, availability schedule, and more.

If you need to learn about RDF, please visit our RDF Tutorial.


OWL - Web Ontology Language

OWL is a language for defining ontologies.

Ontologies describe domains of knowledge. They can be used by humans or software to share information about objects such as cars, houses, machines, books, products, financial transactions, etc.

OWL is designed for processing information (rather than presenting it).

If you need to learn more about OWL, please visit our RDF Tutorial.


SPARQL - Query Language for RDF

SPARQL is a standard query language for RDF data, providing developers with a way to write queries across a wide range of RDF information on the Web.
