Tool and software building in the open source space has proceeded completely organically, with most tools built by various companies that decided to release specific things open source.
I spent quite a bit of time, as well as Tony Shannon whom you will remember, on the document attached here, which was circulated some years ago, but we got no traction. That’s no criticism of anyone; we probably would have hoped for some proper funding, maybe from NHS, Wellcome, a European source, or possibly big tech, to help get a more coherent approach off the ground. While there is patchy funding, there will only be patchy open source offerings.
We actually spent a lot of time thinking about how Apache works (in particular), and devised a governance structure that you will see in this document.

More recent efforts (about 3y ago) by myself and a few others to get a Software Program Board moving did not attract much interest.
Anyway, ‘organisation’ can only come from a common roadmap that everyone more or less agrees to, and gets progressively filled in with various components, tools etc. A realist view of this would be that not everything in the roadmap has to be OS, it just has to have defined and stable interfaces.
People in the Software Program might want to revisit this document if they have not seen it.
