Appropriate License For Supplemental Data

[Sunburned Surveyor]

I had another licensing question for the OSM legal gurus. :]

I hope to release supplemental data for my OSM mapping projects in an
effort to improve the quality of the data and to make it more
palatable for traditions GIS systems. Part of this supplemental data
will be digital photographs of mapped features, digitial photograph
descriptions, the actual coordinate data (waypoints) used for the
mapping, and information on the data collection missions used to
create the OSM data.

Does anyone see a problem with releasing this information under the
same license as the OSM vector data? What about using a different
Creative Commons License? Would this create a conflict?

Thanks,

The Sunburned Surveyor

Please have a look at:

http://wiki.creativecommons.org/Frequently_Asked_Questions#If_I_use_a_Creative_Commons-licensed_work_to_create_a_new_work__.28ie_a_derivative_work_or_adaptation.29.2C_which_Creative_Commons_license_can_I_use_for_my_new_work.3F
(If the link fails, that's section 2.15 in the CC FAQ)

In other words, if you want that data to be used in OSM with no issues, you
should license it with a PD, CC-by, or CC-by-sa license.


Also, keep in mind that releasing anything under any license doesn't mean that
you lose the rights to it, particularly the rights to re-license it. For
example, if you release some data under CC-by-sa, you can then sell that same
data, and you can then publish it under PD. That's called "dual licensing",
and it's the tool that artists who publish under CC-by-nc use for selling
their works and making money.

I say this because a new license, the Open Database License (ODbL) is in the
works, and OSM will eventually adopt it for the vector data, AFAIK. It means
that you might have to re-license the supplemental data under a license
compatible with the details of the ODbL, which may not be a CC-by-sa.


Cheers,
