RESUMO

Documents have been the main vehicle of the Web until some years ago. With the advent of Web applications, data stored in organizations databases or legacy systems has been made available to users. However, very often, the exchange of data between those applications themselves or between them and end-users applications were not possible since they used different formats for the information representation. The development of standards and the use of the eXtensible Markup Language (XML) solved parts of the problem. That was a syntactic solution and it works for several cases, e.g., schema interoperability in Business-to-Business e-commerce scenarios. Nevertheless, the lack of semantics on these data prevented applications to take more advantage of them. The idea behind the Semantic Web is to define explicitly the semantics of data available on the Web. Therefore, we expect another step forward where applications, being them corporative or for end-users, will understand the meaning of the data available on the Web. Once those applications can understand it, they will be able to help users to take advantage of this data driven Web and to perform their daily tasks easily. This thesis proposes a framework for the development of Semantic Web applications. Considering the scenario described in the previous paragraph, the number of possible applications that can be developed is almost infinite. For this reason, we restricted ourselves to examine the solutions that aim to solve the problem presented at the Semantic Web Challenge; and to propose a framework that represent those solutions. The challenge is concerned in demonstrating how Semantic Web techniques can provide valuable or attractive applications to end users. Our main concern was then to demonstrate and help a developer to achieve that value addition or attractiveness, through Semantic Web techniques, in a Software Engineering approach using frameworks.
