The process for getting non-embedded (replicated) codelist changes into the standard was previously documented here: https://github.com/IATI/IATI-Extra-Documentation/blob/9c54e586/en/codelists-guides/codelist-management.rst#updates-to-non-embedded-codelists
I don’t know if this process has changed, but I don’t think it’s documented anymore. See: http://reference.iatistandard.org/203/codelists-guides/codelist-management/#non-embedded-codelists-replicated
What is the process now? I’m asking specifically with reference to the recent (July) DAC codelist updates, as well as this bugfix to re-add a number of removed withdrawn sector codes.
