Dear [Contact],

Thank you for making [entity]'s [dataset] available under the Creative Commons CC BY 2.0 license.

I am a volunteer of OpenStreetMap, a collaborative open project to create a global geodata set freely usable by anyone on share-alike and attribution terms under the Open Database License (ODbL).

We’re very interested in using the data in [dataset] to improve OpenStreetMap. In order to facilitate this, we need to confirm with you that [entity] has no objections.

In particular, there are two issues we would like to clarify.

First, because OpenStreetMap's data comes from thousands of local volunteers as well as numerous government sources, attribution to all such sources on an OpenStreetMap-based map or similar visual display is impossible. Instead, we provide attribution (including original license information) to major sources like [entity] on our Contributors page. OpenStreetMap users are then required to attribute "OpenStreetMap Contributors" in a collective fashion when using any OpenStreetMap data. CC BY's attribution requirements are relatively general, so we just need you to confirm that you would consider OpenStreetMap's attribution method to attribute [entity] in a "reasonable manner" that is “reasonable to the means and medium” in accordance with Section 4(b) of the CC BY 2.0 license.

Second, CC BY 2.0 requires downstream users to provide notice of the terms of the CC BY 2.0 license and not use technical measures to restrict future use of the [dataset] under the CC BY 2.0 license. We ask that you confirm that OpenStreetMap’s method of providing links to the original dataset and original license terms on our Contributor's page satisfies the requirements of Section 4(a) of the CC BY 2.0 license.  

Further, the ODbL allows data users to apply technical protection measures to their own works so long as they also provide an unrestricted version of the underlying database, including their own additions ("parallel distribution").  While CC BY 2.0 does not specifically address projects such as OpenStreetMap that incorporate data from CC BY sources, some might read CC BY 2.0 to prohibit any application of technical protection measures to databases that include CC BY material and, out of an abundance of caution, avoid CC BY 2.0 datasets for such projects.

In practice, we have found that parallel distribution is an excellent way of ensuring open access to data while allowing flexibility in use. Thus, we ask that, to the extent CC BY 2.0 Section 4(a) prohibits any downstream restrictions even when parallel distribution is available, you waive this license restriction as to OSM and its users. This waiver would have no effect on [entity's] original dataset and only pertains to the restrictions allowed on combinations of that data with OSM data.

Thank you for your consideration. If [entity] is amenable, can you please fill out the attached form and return a signed version to me?

If you have any questions or would like more information about OpenStreetMap, please do not hesitate to contact me by e-mail.

Regards,

Local OSM Representative

Permission to Incorporate CC BY Data Into OpenStreetMap

With respect to [dataset], [entity] agrees to the following:

  1. Attribution by OpenStreetMap and its users through http://wiki.openstreetmap.org/wiki/Contributors is sufficient to provide attribution to [entity] in a "reasonable manner" that is “reasonable to the means and medium” in accordance with Section 4(b) of the CC BY 2.0 license.
  1. OpenStreetMap’s method of providing references to the original dataset and original license terms through http://wiki.openstreetmap.org/wiki/Contributors  satisfies the requirements of Section 4(b) of the CC BY 2.0 license.  OpenStreetMap users satisfy the requirements of Section 4(b) of the CC BY 2.0 license by referencing http://wiki.openstreetmap.org/wiki/Contributors in accordance with OpenStreetMap’s attribution requirements.  [Entity] waives any limitation in Section 4(a) of the CC BY 2.0 license on OpenStreetMap and its users using effective technological measures on OpenStreetMap data with the understanding that this waiver has no impact on [Entity]’s right or ability to distribute or license [dataset] on any terms it wishes.
