I'd say that we would want to let the user specify title, and the URL
of the remote album.

As for storing stuff locally in our JCR repo and fetching it all the
time, we should have metadata stored locally to allow searching.

As for how we go about approaching this, I'd recommend that we start
with retrieving it from the remote site and storing in a local cache
(e.g a map) inside of a @Scope("COMPOSITE") component, and then on a
second phase, we would add the full blow sync and test searching, etc.

Thoughts ?
