The consistent web: a vision for the future

ABSTRACT

Over the past decade, the World-Wide-Web has become the preferred vehicle for information dissemination on a global scale. However, no guarantees as to the consistency, or correctness, of the content being provided are made. In this paper, a novel vision of a Consistent Web is proposed. Unlike in the current system, time will have a direct influence on whether requests for specific content should be satisfied. Firstly, the motivation for the work and the limitations of current consistency management techniques are discussed. The concept of a Consistent Web is then presented, and by way of several examples, an illustration of the type of functionality it offers is provided. Finally, an outline of the research strategy to be employed is given.
