Now when I follow the link you provide above, as well as https://incubator.apache.org/ip-clearance/index.html ...I only observe a process where the 3rd party formally transfers code to the ASF. (In which case it doesn't really matter how the code was originally licensed.) For the purpose of this discussion, I was interested in exploring the path where there's some code on the internet that is Apache licensed, and the IP provenance is easy to confirm, so one would think we can easily copy parts of such code into an ASF project that of course also is Apache 2.0 licensed. The copyright of course would continue to belong to the original author of the code. (MongoDB) I get the impression this isn't actually done a lot in ASF projects? To be clear, I'm not against having this discussion on the private list and approaching MongoDB for a more serious discussion about this. I'm just wondering since being able to copy code between projects is one of the greatest benefits of working with OSS licensed code, it's kind of ironic if that way of working isn't available to ASF itself. Also, I agree that the amount of code we're talking about isn't non-trivial, so this discussion at least, if not the ensuing paper work, is entirely justified. > The IP Clearance process while done in the Incubator is for PMCs and not > podlings. > > Sorry, can you clarify this sentence? > >> 2c.

A lot of the code is duplicated, where the same 100+ lines of code is implented 5 different ways in order to explore performance differences. But as said, I agree it isn't insignificant. Let’s review those comms on the private list. Essentially we can start from a clean slate there. henrik -- *nyrkio.com <http://nyrkio.com/>* ~ *git blame for performance* Henrik Ingo, CEO hen...@nyrkio.com LinkedIn: www.linkedin.com/in/heingo +358 40 569 7354 Twitter: twitter.com/h_ingo
