Before anyone starts massively using OS data for anything else than a
comparison, I strongly suggest to get a very clear view of this,
either
by having the OS say "yes ok" or at least getting a statement from
our
own licensing working group.

I for one have still yet to trace anything from OSSV, even though I am
desperate to do the local watercourses, because I am still unclear on
this point. I am only a relatively minor contributor, but I want to be
able to accept the contributor terms, should that ever time come,
without hestiation and without deleting any of my work first.
Perhaps I
am overcautious and may eventually succumb to temptation on a bit of
local tracing (where I am happy I could accept deletion if necessary),
but I am mildly alarmed at the prospect of large-scale use of this
data
without a bit more clarity regarding the compatibility of ODBL.
The OS page on the wiki it has the following simple statement
regarding the license with no caveats which sounds fine....
'According to the OpenData License Terms and Conditions, all data can
be safely assumed to be under a CC-by 3.0 license - the T&C Explicitly
say so.'
http://wiki.openstreetmap.org/wiki/Ordnance_Survey_Opendata
However..... on the 'Closed issues' section of the ODBL license is
states that ODBL may be incompatible with data supplied as CCBYSA and
states that contributors using such resources 'should get the
permission of the original data provider to relicense it to ODbL'.
http://wiki.openstreetmap.org/wiki/Open_Data_License/Closed_Issues
I note that the OS data is CCBY not CCBYSA which may be relevant to
the issue, I don't know. I have also noted that the government clearly
wants the data to be used and is unlikely to sue, however the
Foundation have stated that they will remove all data that is derived
from CCBYSA (and CCBY?) !
Are the license working group or the foundation researching this for
us? The question is simple. Is the OS Open data compatible with ODBL
and if not then are they following it up and how are the discussions
going?
Incidentally I see nothing about it in the license working group
minutes relating to the OS data since it was released on 1 April.
