For the record, part some tooling that I am building and preparing for SEC (Specification program) to maintain the specifications docs, I created this marketplace repo https://github.com/openEHR/ai-plugins to define the openehr-specs plugin.
This repo can in the future host other plugins - if you have any in mind. I guess @marcusbaw or somebody else from SPB can think about categorizing this repo properly in the near future - I am happy to have me or somebody else from SEC maintaining this first plugin.
