The [DBpedia Archivo Databus agent](https://databus.dbpedia.org/ontologies) generates only basic, static documentation for the archived snapshots of the ontologies. More, augmented and dynamic information for this ontology is rendered on and retrievable via [DBpedia Archivo Frontend](http://archivo.dbpedia.org/info?o=http://purl.org/qb4olap/cubes).

## Ontology Metadata

DBpedia Archivo extracts metadata from the ontology for well known properties (e.g. dct:description). This subsection shows the content of every property individually using a separate heading.

### rdfs:comment

This vocabulary, named QB4OLAP, is an extension to the DataCube vocabulary that allows to represent OLAP cubes in RDF, and to implement OLAP operators (such as Roll-up, Slice, and Dice) as SPARQL queries directly on this RDF representation.
