Hi, I spend a several days investigating several free software, content, database licenses that could probably suit my objectives, and I believe that the ODbL is the closest to what I have in mind. However, I suspect that my end-users would find it difficult to comply with section 4.3, since my end-users might seek to utilize their Works Produced in real-time within a persistent virtual space. It would be rather annoying if the license were to force them to carry a sign or wear a watermark.
I’m wondering if it would be fine to create a license of my own using the ODbL text as a base, toning down section 4.3 in order to permit for less visible means of providing attribution (e.g. through metadata). Mozilla and the GNU project permit others to craft their own licenses based on their existing licenses, so I’m wondering if the Open Knowledge Foundation permits the same.
