We are currently writing a piece of software. In it, we want to use the Disconnect.me tracking services list. The list is licensed under the GPLv3. Our code will generally only run on servers, but we plan on releasing it under the MIT license. The tracker file will not be distributed with the software, but the setup script will automatically download it from the official source. It is then read and parsed in our software, and used to match URLs against it.
Leaving aside the issue that licensing datasets under the GPL is discouraged (since it was not our decision), what are the consequences for our final code? Since the file in question is a JSON data file, I am not sure how the different forms of linking vs. fork-and-exec apply to it. Is this "modularized enough" that this use would be acceptable, or does this use already make the whole system a combined work and thereby require licensing the whole thing under the GPLv3?
