Hi everyone,

I've started a proposal for pushing ACIs. Please see and comment here:

Capturing OOB discussion - we should consider how to deal with image dependencies (layers).

Why does appc need this functionality? I haven't seen the rationalization in the doc nor here.

[jonboulle]

@blalor The simplest argument would be one of symmetry - if we describe a means for discovery retrieval it would also be good to have the inverse. This helps close the loop for distributing appc images (but still without prescribing means of transport, etc).

At a more practical level, we need something that works for Quay -- but we think it can be more generally useful.

Having said that, this is by no means a finished discussion. Would love to hear your viewpoint.
