Declaring relations between cubes

Description:

In some situations statistical data sets are used to derive further datasets. Should Data Cube be able to explicitly convey these relationships?

A simple specific use case is that the Welsh Assembly government publishes a variety of population datasets broken down in different ways. For many uses then population broken down by some category (e.g. ethnicity) is expressed as a percentage. Separate datasets give the actual counts per category and aggregate counts. In such cases it is common to talk about the denominator (often DENOM) which is the aggregate count against which the percentages can be interpreted.

Should Data Cube support explicit declaration of such relationships either between separated qb:DataSets or between measures with a single qb:DataSet (e.g. ex:populationCount and ex:populationPercent)?

If so should that be scoped to simple, common relationships like DENOM or allow expression of arbitrary mathematical relations?

Note that there has been some work towards this within the SDMX community as indicated here: http://groups.google.com/group/publishing-statistical-data/msg/b3fd023d8c33561d
