Jody, The data is originally derived from the EPSG database which has the following statement on the "use of data". 1) All data pertinent to a specific coordinate reference system must be copied without modification and all related pages/records must be included; 2) All components of this data set pertinent to any given coordinate reference system must be distributed together (complete distribution of all components of the data set is preferred, but the OGP recognises the need for a more limited distribution); 3) The data may not be distributed for profit by any third party; and 4) The original source [OGP] must be acknowledged. The user assumes the entire risk as to the accuracy and the use of this data. The data may be copied and distributed subject to the following conditions: INFORMATION PROVIDED IN THIS DOCUMENT IS PROVIDED "AS IS" WITHOUT WARRANTY OF ANY KIND, EITHER EXPRESSED OR IMPLIED, INCLUDING BUT NOT LIMITED TO THE IMPLIED WARRANTIES OF MERCHANTABILITY AND/OR FITNESS FOR A PARTICULAR PURPOSE. With regard to (3) above, the data may be included within proprietary applications distributed on a commercial basis when the commerciality is based on application functionality and not on a value ascribed to the freely-distributed EPSG dataset. As I see it, several of these points are contrary to the Open Source Definition, which suggests that EPSG derived datasets should not be distributed as part of an open source package *if* they are considered source code. However, it is common for open source packages to distribute documentation under licenses that disallow changes for instance. I'm not sure what the implications are for us. I will follow up with Rich Steele. Also there is some question whether we are in violation of (1) and (2) by not distributing everything known about coordinate systems. For instance, "remarks" are discarded in the translation to WKT and PROJ.4 format. Lastly, we do need to properly acknowledge OGP as the source of the data in source and binary distributions.
