Dear Overture Team and OpenStreetMap Community,

This diary entry is a follow-up to an in-person conversation I had with some of the Overture team at State of the Map U.S. To their credit, they were quick to admit to and apologize for some of these omissions and verbally committed to making appropriate changes. I am therefore posting this entry for the following reasons:

• to fully document my concerns,
• to invite others to (respectfully please!) share their perspectives,
• to hold the Overture team accountable for making these changes.

Clarity on Attribution Page

In my opinion, Overture does not take care to spell out the necessity of OpenStreetMap attribution on their Attribution and Licensing page. After an optional citation comes the following language:

The Overture Maps Foundation does not require text attribution or an OMF logo on maps, visualizations, and graphics created with our datasets. If you would like to credit Overture, we suggest: © Overture Maps Foundation.

So far it seems pretty easy to use Overture data. We can attribute…but only if we want. Easy peasy! After that, the potential for additional attribution requirements is raised:

Some of the data sources we use in Overture datasets do require their own attribution, according to their licenses. For example, our Explore tool displays several Overture datasets that are made wholly or in part from OpenStreetMap data, so we added the following line of attribution to adhere to the requirements of the Open Database License: © OpenStreetMap contributors, Overture Maps Foundation.

Let’s take a close look at this paragraph. In Overture’s only mention of OpenStreetMap attribution requirements (that I could find), they frame it as a passing example. It’s as if the OpenStreetMap community should feel lucky that Overture chose us as their example of potential attribution requirements. To me, this deflection of our dataset’s license comes across as deeply disrespectful.
