hi folks, For new committers especially: please be mindful when reviewing patches when code may have originated from some other body of IP, like another open source project. If you come across a segment of code which may have been copy-and-pasted from somewhere else, please ask the contributor where the code came from. If it is not original IP contributed to Apache Arrow, in general it must be noted in the top level LICENSE.txt file for the project. Please verify that the license for the project is part of the Category A list on
https://www.apache.org/legal/resolved.html Code with copyleft (GPL or similar) or weak copyleft license (Mozilla Public License, and others) may not be included in the project except in cases where files were generated by some form of build tool. These are the Category X and Category B license groups. Code contributed to StackOverflow prior to February 1, 2016 may not be used because of the license, read more at https://meta.stackexchange.com/questions/271080/the-mit-license-clarity-on-using-code-on-stack-overflow-and-stack-exchange My understanding is that SO code after 2016-02-01 is available under the MIT license, but its IP provenance should be noted at the point of use (post link back to the SO answer in a code comment at least) - Wes
