Maybe I am doing it wrong, but I expect it like in users and the like, so I send this to add a new group:

{id: 591, source: {name: "CUP", id: 540}, reference: null,…}
curatoryGroupIds: [752573]
id: 591
ids: [{value: "fdfgf", namespace: "global"}, {value: "12345", namespace: "doi"}]
reference: null
source: {name: "CUP", id: 540}
variantNames: [{variantName: "University of Iowa Libraries"},…]

Actually this is not working.
