 =?UTF-8?q?,=20catalogue=20prestataires=20et=20sch=C3=A9mas=20draw.io?=
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

- Fiche d'identité par organisation (technicien référent, FAI, IP publiques,
  prestataires liés) accessible depuis un nouveau menu.
- Nouveau module Prestataires dédié (catalogue léger réutilisable entre
  communes, avec journal de suivi des échanges) plutôt que de détourner les
  organisations de type "Fournisseur".
- Nouveau menu Infrastructure par organisation avec schémas réseau/fonctionnel
  édités via draw.io embarqué (URL configurable, cf. réglages admin).
