OLAP Xforms

A long time ago we used to have an OLAP processor based on Mondrian in
Orbeon Forms. Since there was zero demand for it we stopped working on it.

It could be possible to revive this code. It is still available under
MDXProcessor.java. This was using Mondrian in an embedded way. Maybe
there is now a better way to communicate to Mondrian. I see in their doc
now that they support XML for Analysis, which is SOAP-based, and could
be called directly from XForms:

Mmh, we had an example, probably all the way back to OPS 2.8. Check the
files section to get 2.8:

The processor is still present in the latest Orbeon Forms. The processor
name is oxf:mdx.

I can't see any example checked in. We used to have some example for
the MDX processor, but those must have been deleted at some point.
Since Mondrian supports a standard SOAP interface (XML for Analysis),
I would recommend you use that interface to talk to Mondrian.

If you want to write Java code, and you want to write your own
processor, you may or may not find the code in the MDX processor
useful, but this is not the route that I would explore first.
