I'm trying work out the best way to structure our API; we have Reviews which we've setup in a standard REST structure (list one, list all, create, update etc). Where it doesn't quite fit the examples is: each review can be linked to one or more other types e.g. Event, Location or Thing.

My thinking is the urls would be along the lines of: /event/reviews/ (or the reverse of this e.g. /reviews/event/) /location/reviews/ /thing/reviews/

The issue I can see however is the "GET" for each of these should return the parent object i.e. an Event.

So using ServiceStack, what's the best way to handle this scenario? Is it to create a custom service for each data request rather than abusing the out-of-the-box REST setup or have I missed something more fundamental?
