For today{\textquoteright}s business dynamics, sometimes these highly curated data is not enough. External data (particularly web data), may be useful to enhance local analysis. In this paper we discuss the extraction of multidimensional data from web sources, and their representation in {RDFS.} We introduce Open Cubes, an {RDFS} vocabulary for the specification and publication of multidimensional cubes on the Semantic Web, and show how classical {OLAP} operations can be implemented over Open Cubes using {SPARQL} 1.1, without the need of mapping the multidimensional information to the local database (the usual approach to multidimensional analysis of Semantic Web data). We show that our approach is plausible for the data sizes that can usually be retrieved to enhance local data repositories.},
