RDF Data Cube
The W3C Government Linked Data Working Group has started work towards making Data Cube a W3C Recommendation. See here: http://www.w3.org/2011/gld/wiki/Data_Cube_Vocabulary
There's an Editor's Draft of the spec (content-wise so far identical to the old spec on Google Code): http://dvcs.w3.org/hg/gld/raw-file/default/data-cube/index.html
There's also a very rough first cut on a Use Cases and Requirements document: http://www.w3.org/2011/gld/wiki/Data_Cube_Vocabulary/Use_Cases
Dave and Richard, FZI's Benedikt Kämpgen and are working actively on this.

ESDS International has recently completed a project where they looked at using the Data Cube Vocabulary to describe world back data, here’s the link to that data.

In [1], we have used QB with Mondrian and XML/A clients.
Momentarily, we are working on an OLAP4J implementation [2] to allow common OLAP clients to access QB data. So far, for visualization, we have been thinking of using Saiku [3], which connects to the OLAP4J API. As soon as I have a demo, I can post it here.
