News today from Mike Collinson, Chair of the OSMF License Working Group:
As promised, and long awaited, the next phase of the OSM License
Upgrade has arrived. Phase 2 - Existing Contributor Voluntary
Re-licensing  has begun, and you may indicate your acceptance of
the new Contributor Terms for your existing OSM API account. To
accept the terms visit http://openstreetmap.org/user/terms, (you may
be asked to login first), or your user settings page.
Please note that OpenStreetMap is not changing the license on any
published data at this point. Existing contributors are being asked
to permit re-licensing of their data in the future when it makes sense
to do so.
There is no decline button, and no obligation to answer yet. Existing
Contributor Voluntary Re-licensing is for those who wish to accept the
terms and get on with mapping.
We'll be publishing which users have accepted so that we can all see
We hope that you will accept the new Contributor Terms  and ODbL
for each of your user accounts if you have more than one.
** Why are we doing it like this? **
What ifs, what ifs. The key is clearly to reduce these. Those that
simply want to get on mapping and accept that we won't doing anything
daft, can sign up. Those that are worried about data loss and that
the OSMF will make a stupid decision, can wait and see. We'll show
how much of the database is potentially covered by the ODbL. We've got
some help on modelling that, and we'll aim for at least a weekly
update if not daily. We'll also make all the data available needed to
calculate that, so if you want to try a different metric or just see
what is happening in your local area, everything will be transparent.
If you support the share-alike concept, I urge you to accept the new
Contributor Terms which provides for a coherent Attribution,
Share-Alike license written especially for databases. If you are a
Public Domain license supporter, we are divided as a community on
which is best and I do urge you to give this one a good try. The
Contributor Terms are expressly written to allow us to come back in
future years and see what is best without all this fuss about
procedure. And if you'd just really like all this hoo-haa to go away
and get back to mapping, well, please say yes.
** Some supporting notes: **
() The key thing is that there are about 12,500 contributors who have
contributed over 98% of the pre-May data.
() I personally really, really want to get a coherent license in place
so that my mapping efforts are more widely used. I also really, really
don't want us as a community to shoot ourselves in the head and
divide. I pledge to continue working with *both* objectives in mind.
() The License Working Group will not recommend switching over the
license if data loss is unreasonable . We will issue a formal
statement to that effect and are attempting to define better what
"unreasonable" means. A totally quantitative criteria is extremely
difficult to define ahead of actually seeing what specific problems
may arise. But I understand the concern that we are tempted to do
() The License Working Group will ask the OSMF board to issue a
() We are working to create a process whereby we can model on a
regular basis how much of the OSM database is covered by ODbL and how
much not. We will make all the data needed to do that public so that
anyone can analyse using their own metrics. Work on this is active and
being discussed on the dev mailing list. You will need:
- An ordinary planet dump.
- Access to history data. A public 18GB "history dump" is available
The intent is to make this available on a regular basis with difffs. A
full re-generation takes several days.
- A list of userids of who has and has not accepted the license. Work
() A final vote on whether to switch or not remains an option. But let
us see first if "data loss" really is an issue and what the specific
problems might be.
Regards to all,
License Working Group
