A colleague and I were recently approached by a publisher of educational materials regarding licensing the data from our paper, "Studying the Internal Ballistics of a Combustion Driven Potato Cannon using High-speed Video". See: http://arxiv.org/ftp/arxiv/papers/1305/1305.0966.pdf This is somewhat new territory for us. Has any of the PF readers or contributors been through this process before? We are generally willing for the data to be used for positive educational reasons, but we would like to both protect our interests and ensure that our data is used correctly (that the physics is right). Any suggestions?
