Abstract
To make use of data represented on the Semantic Web, it is necessary to provide languages for Web data retrieval and evolution. This article introduces into the (conventional and Semantic) Web query language Xcerpt and the event and update language XChange, and shows how their deductive capabilities make them well suited for querying, changing and reasoning with data on both the conventional and the Semantic Web. To this aim, small application scenarios are introduced.
