On the serializer config for the Hypermedia control (HAL) here : https://github.com/gimler/symfony-rest-edition/blob/2.7/src/AppBundle/Resources/config/serializer/Model.Note.yml#L32
the word "embed" used for the embedded objects, is it the right one ?
Because on my side doesn't work ...
If I change embed to embedded works fine for me .
I can do a PR If you want to fix the issue, if it's an issue of course.
