The mapping data tables cannot be non-proprietary because the AIS content is protected by copyright and is available only through licensing from the AAAM. Since the maintenance and updating of the AIS is accomplished through the AAAM, which is a non-profit 501(c)(3) organization, the map is available for a nominal fee. Additionally, any organization that creates such a map for commercial or research needs to complete a licensing agreement with AAAM as all users of AIS 2005/2008 are compelled to be licensed according to the intellectual property rights surrounding use of the coding system.
