[OSM-legal-talk] ODBL and imports

2014-04-25 Thread Erik Johansson
I've been thinking about this for quite some time, but have not been
able to come up with anything useful so please help me. I think we
have a big problem with the choice of CT + ODBL, it is very unclear to
people that ODBL data can not be uploaded to Openstreetmap. It's
obvious that the data is licensed as ODbL, but the issue that all
contributors must agree to CT is a bit  hidden

The first question is exactly what license should I ask people to
license their data as, if I'm supposed to beable to use it in OSM? The
second is if should be made clear that we do not accept ODBL licensed
data.

One example which seemed the most simple way to do it to me, but
suggestions on how to do this easier is very appreciated:

Have a nice weekend!

The LWG might actually publish a formal guideline on the subject, but my
informal 2c for now:

- it is fairly clear that you -could- import 3rd party ODbL licensed
data under the CT (naturally assuming every other box for an import has
been ticked too). The CTs only require compatibility with the current
OSM licence and that is a given (there are a few other details that need
to be observed, but that is the big one).

- it is just as clear that importing anything that may conflict with a
future licence change runs the risk of being removed at such a date.
Slightly opinionated comment: as one of the people that had to deal with
numerous importers that choosed to ignore what was going on during the
licence change: if there is a next time the position will be that you
were forewarned and are getting exactly what you asked for.

- which leads to the question -should- you import ODbL licenced data.
Obviously the answer to that is highly subjective, my position is that I
wouldn't, but others may differ.

So, you mean that the main objection to import ODBL data is a future
licence change. But I remember some past messages here or elsewhere
that the licence process is so heavy and requires so high acceptance
that a licence change is almost impossible... (note that this argument
would invalidate all types of third party licences and finally all
imports).

Naturally any import that is not CC0 licenced or is PD has the potential
to cause problems if and when a further licence change is considered.

But this is a continuum from would cause a lot of issues to more or
less OK. For example changing to a licence that does not support and
require attribution would essentially cause a massacre and is unlikely
to ever be seriously considered. But as a consequence I personally would
consider CC by and other licences that essentially only require some
kind of attribution as not tying our hands more than they already are
and insofar as unproblematic.

As already said, this is only my personal opinion.

I probably should have added that I see no problem at all with the terms
Mapillary specifies, since for contributions to OSM it only specifies
that it should happen under the terms of the CTs. IMHO naturally.
