The developer of Ginko, @vjrj, should create an RFC for this format and discuss it with other developers to reach agreement.

The prefix is problematic: “june” is not the correct name; it should be “g1”. Additionally, there have already been previous standardization attempts that should probably be reused: [G1link syntax review / Choisissons la syntaxe G1Lien](https://forum.duniter.org/t/g1link-syntax-review-choisissons-la-syntaxe-g1lien/7522)

cc @1000i100 @poka @kimamila is there already an RFC somewhere? I didn’t find it on [documents / RFCs · GitLab](https://git.duniter.org/documents/rfcs)
