Not mine :-)

I know Marc Blanchet was involved in developing it, because he asked me some questions, but honestly I do not know. You must ask IANA.

I had my code ready (I actually have two versions of the code, ruby and python -- where the ruby code is completely written from base up while python use some external libraries for a few things) when IANA started to implement theirs. I asked them to ensure they would develop their code completely independent from mine.

What we do though is that when IANA has calculated a new version of the tables (for a new version of Unicode) I do the calculations as well with my code. I do a diff, and if there are no differences, then I say "go" to IANA and they make the new version available.
