[Live-demo] What dataset should your application use on the LiveDVD?

Ok, based upon advice from this thread, I've created an 
"install_gisdata.sh" script, which downloads the following naturalearth 

# Poly: Admin 0 - Countries 1:110m
# Point: Populated Places (simple, less columns) 1:110m
# Poly: Land 1:110m
# Poly: Ocean 1:110m
# Poly: Lakes + Reservoirs 1:110m
# Line: Rivers, Lake Ceterlines 1:110m
# Raster: Cross Blended Hypso with Shaded Relief and Water 1:50m

Hamish, I've copied the installing of the Barcelona.osm dataset from 
install_osm.sh, except instead of calling it barcelona.osm, I'm calling 
the dataset highlightedcity.osm
The reason for this is that I'm wanting to ensure that we can change the 
dataset year to year without effecting application examples which use 
the dataset.
Is this realistic? Can applications determine the area of interest from 
an OSM file?

Hamish, could you please review this script, and if you are happy with 
it, remove the corresponding lines from install_osm.sh

I think we will want to include a number of the datasets that you have 
mentioned for Barcellona.
Could you please copy across a minimal set of script lines for 
installing Barcelona data from your scripts. (This may be all of the 
We will also need to clearly specify the licence for your datasets 
(which I assume is Creative Commons, or some other Open type licence). 
We will create a Description and Overview documentation page for our 
data, which will include a description and licence.
