Creation of a sharing controller

[paultranvan]

In order to implement the cozy-to-cozy sharing, we need to create a sharing controller. As a first iteration, this controller could be conceptually split in 3 parts :

• Creation (sharing creator) : creates a Sharing document including the sharing metadata (recipient urls, description, docids, etc), and sends a sharing proposition for each recipient (could be considered as a Cozy notification).
• Validation (sharing recipient) : called when a recipient accepts or denies a sharing proposition. If accepted, it creates a new Access document for this sharing. The answer and the credentials (if any) are sent to the sharing creator.
• Answer (sharing creator) : depending on the recipient's answer, saves the credentials and triggers a CouchDB replication, or removes the recipient from the Sharing document.

Maybe, it's better to call it 'sharing service' instead of 'sharing controller', as controller has a specific meaning in cozy.

I think @Gara64 talks about Express/Americano controllers.

But on the architectural point of view, we could include it as a service like we talked for files.

Yes, I meant an Americano controller, but this could indeed be viewed as a service.
