On-Line Analytical Processing (OLAP) promises an interface to analyze Linked Data containing statistics going beyond other interaction paradigms such as follow-your-nose browsers, faceted-search interfaces and query builders. As a new way to interact with statistical Linked Data the authors define common OLAP operations on data cubes modelled in RDF and show how a nested set of OLAP operations lead to an OLAP query. Then, they show how to transform an OLAP query to a SPARQL query which generates all required facts from the data cube.
