In this paper we address an issue common in the frame of WWW, namely information entities that present di erent facets under di erent contexts (or worlds). Handling such multifacet or multidimensionalentities requires a multidimensional paradigm for Web data, which consists of representation, manipulation and presentation issues. For representing multidimensional data we employ Multidimensional XML, a markup language that incorporates dimensions in XML. We discuss the presentation of multidimensional data through multidimensional XSL stylesheets. We describe the design of a system that implements the basic functionality of the multidimensional paradigm, and demonstrates how a user can interact with a multidimensional document and view di erent variants of the document under di erent worlds.
