Sample Data
I think for the sample data it is important, that the data is not too 

It would be great if it would fit to the data we already have

About the documentation.
Each project has to provide an overview document and a quickstart.
see https://live.osgeo.org/en/overview/overview.html
On Github at: https://github.com/OSGeo/OSGeoLive-doc/tree/master/doc
the line in the csv file gathers some overview information that is used 
to setup the documentation pages
