There is one thing about this data set that I would like to change - the name of the location itself.
Given that distribution of data by mapsets does not work well, all data sets should be distributed as locations
(or external data) and then we won't need the loc part in the name.
So I suggest to use the name


instead of loc_ncspm_baseline

and we should have a single place where this data set is stored (on grass website under data?)
to avoid creating multiple versions of the data set. I will remove mine and replace it by a link.

Then the italian version of this data set would be

Do you think we should add it to each example which needs it? For tests it would be quite easy to do something like set up the search path automatically according to existing mapsets or search path set in PERMANENT but it is desired? I don't have a strong opinion, explicit g.mapsets calls sounds as a safe way to go but putting @mapsetname everywhere would also work, am I right?

I suggest to distribute all mapsets with at least the baseline data set in PERMANENT. Then you would have to deal with data in different 
mapsets (and in fact in different locations) only for the examples where you need to combine data from two or more different
specialized mapsets - for example lidar and networks.

I agree - we should retire all other small data sets and mark them as retired, although I expect that nc_spm_08 and nc_spm_08_grass7 will be still used for a while.
I will post the relevant notes on my website and in our courses as well.

I agree.

GRASS7.1 would be a good target. I am also working on a new external data set and on locations in other coordinate systems with some limited but hopefully meaningful
map layers in them.
