QB4OLAP is a RDFS Vocabulary for Business Intelligence over Linked Data.
In this project we include a set of prototypes that conform a showcase of what can be done using this vocabulary, focusing on exploring and querying.
For querying we propose a high level OLAP language, called QL, which consists on a set of well-known operators:
rollup, drilldown, slice, and
dice. Using the cube metadata, also written using QB4OLAP, we automatically generate SPARQL queries to implement sequences of QL operations.
