Hi Fabio, I probably missed some previous conversation about this: why is usedBy deprecated? This is something we use in https://github.com/codegouvfr/awesome-codegouvfr/ and this is a useful information we want to promote. Is it replaced by something else?

Copying my colleague @hjonin on this.

Hi @bzg, it's a proposal that has been cooking for a while now because usedBy comes with many pitfalls. I marked it as a draft while I'm writing the rationale and the various thoughts we've had over the years, so we can have a single place with all feedback we gathered.

It's not final of course, there's still the discussion and voting to be had.

While we're at it, I think we can try and vote the proposals for v0.3.1 of the Standard this month (leaving this one out if there's no clear consensus).

I saw the usedBy also used in the prototype JoinUp catalogue. I like it, but understand there are some pitfalls with a key like this and that it might not completely fit the concept of the standard.

Do you have any idea on how that field is used in that context? Just curiosity
