We recently produced a set of [[ https://www.mediawiki.org/wiki/Core_Platform_Team/Decisions_Architecture_Research_Documentation/Services_Architecture_Recommendations_(2019)#Recommendations_2 | recommendations for our services architecture ]], and during the process, received feedback that some of them should be captured outside the scope of this effort, to be referred to more generally. There seemed to be some consensus that [[ https://www.mediawiki.org/wiki/Requests_for_comment/Standards_for_external_services | Requests_for_comment/Standards_for_external_services ]] might be the right place for this. Some initial efforts at incorporating these has been made at [[ https://www.mediawiki.org/wiki/User:EEvans_(WMF)/Scratch/Standards_for_external_services | User:EEvans_(WMF)/Scratch/Standards_for_external_services ]] ([[ https://www.mediawiki.org/wiki/User:EEvans_(WMF)/Scratch/Standards_for_external_services | diff ]]). It would be great to get a proper review of these changes though, including whether the structure best represents what the original authors intended, before submitting to TechCom for approval.
