Hi there,
I have a question about imports and the ODBl,
I see that some sources have decided to dual license the data
http://wiki.openstreetmap.org/wiki/Import/Catalogue
But how can some third parties data be compatible when the CT says it
can change any time, surly they might be compatible with the current
instance of the license, but how can they be compatible with future
versions of the license when they are no known?
How can a contributor import any data and keep the data open to
license change? How can you keep any imports at all from people who
have not agreed to the CT directly?
thanks

This one has been covered pretty exhaustively previously. To recap for
all interested:
() The CTs where written carefully to say, "If you contribute Contents,
You are indicating that, as far as You know, You have the right to
authorize OSMF to use and distribute those Contents under our current
licence terms." "current license terms", so ODbL 1.0.
() The future is the future, so cannot be known.
() Should the license terms change in the future, there is a possibility
that imported data may become incompatible. Therefore the original
licensor needs be contacted for approval. Given the general trend to
more open data, after what we are all about, that approval may well be
given.
() Note also that, by design, a duty to provide first level attribution
is placed on the OSMF. This survives any potential license change and is
general the most important concern of government organisations.
() The is always the possibility that data may need to be removed and
that is one of the minuses of imports. That is why it is important to
always understand third-party licenses and to get general consent of any
potentially affected, usually national or regional level, OSM mapping
community before importing. There is a healthy debate indirectly about
this going on in the general talk list.
