I really don't see how libgda is an alternative to XSLT, here.  At the
same time, I've seen some kinda specious things about how libgda should
layer against other things...

The meaning of the data is the most painful aspect, and one of the
reasons I'd advocate RDF for the description.

There's a few aspects to what I've been hearing:

* applications providing meaningful and useful data only they 
  [currently] have can make available to callers.
* presenting that roster of data-elements to a user in the process of 
  report-creation.
* visual/print layout of a combination of those elements into a report
  and/or form.

I think goal 1 is a "mail-merge"-like, relatively unidirectional
version. Goal 2 is a more interactive request/response scenario.

Goal 2 is much further past Goal 1; to do it correctly you need to
describe the {data,query}-related capabilities of applications to each
other. [i.e., ReportingTool needs to know the available query-space
which GnuCash can support and how to GET the results of same]; requiring
a human in the loop forgives a multitude of description sins.

Heh.  At the same time, basic XHTML + SVG + MathML with CSS's box/layout
model sure seems to resemble TeX...
