In this paper, we provide a view on the future Web as a Semantic read-write Web. Given a number of prerequisites for enabling a fully read-write Web for machines, we predict the following. First, datasets and data in general will be driven by machine updates. Second, lots of human-created machine-readable schemas will become obsolete. Third, the Web of Services and the Web of Data will be fully integrated into aWeb of read-write Data. Fourth, reasoning on theWeb stays mono- tonic and will be optimized for versioned data. Additionally, two application areas are discussed where the read-write Semantic Web will have a deep impact: the Web of Things and advanced personalisation.
