The project is about adding some external data sources and the possibility
to extend that through extensions. We already have a few providers for
external sources from last year's GSoC project. The second step of
transforming the data before we actually write it to the calc document
itself is independent of the actual source.

Yes. There is already a really ugly UI that I hacked together a year ago.
In a current master build just go to Data->Data Provider and play around.
You might need to define a DB Range before actually being able to import
the data into the document.
As can be seen by the ugly UI there is quite some work necessary to make
the feature user friendly and I think this should be a central part of this
year's GSoC project.
