Abstract
The purpose of this paper is to analyze Semantic Web and Linked Data technologies, with the development of a web application that performs a knowledge modeling through the use of ontologies and RDF (Resource Description Framework) language. A public knowledge ontology/vocabulary was used and populated with data from a relational database from Brazil. The aggregated data was converted to RDF format and made available in an RDF database. The Virtuoso© universal server was used for this task, a hybrid database platform that has the functionalities of a traditional relational database management system, object-relational database, virtual database, RDF, XML, free text, web application server and file server functionality in one system. As a result, a web application capable of retrieving information using the basic principles of the Semantic Web was obtained.
