I think we should decide what we want independently of the REST framework impl, 
to be the most restful possible.

Then we check how to do it in the REST fwk we currently use (restlet) and if 
not possible then we should check if it’s possible with some other REST fwk 
(jersey for example).

At worse, if we don’t want to wait we will need at least to introduce API 
versioning so that we can change it later on easily.

There’s also the suggestion I proposed with several “pages” elements which 
seems potentially more restful than dots to me (but leads to longer urls).

So IMO you should research more about what is the RESTful approach to this 
before we can decide anything.

Thanks
