I'm working on a few wrappers for some web APIs which are under the Apache-2.0 license; for testing I have responses that I've gotten from the real API on the resource classpath to test against. I serve them over an embedded mock web server to verify the data is parsed correctly and any utility methods work.
The saved data is just the raw JSON responses from requests to the respective APIs which include Cleverbot, UrbanDictionary, and various games.
I'm unsure if it's necessary, but I'd like to avoid having references to any content that can be linked backed to an owner or copyright holder in the repository to avoid also redistributing it under those terms.
Is it a good idea to somehow mark these files as excluded from the license?
