Instead of URLs / paths like:
http://ui-prototype.atmire.com/items/86514
We should be using paths based on persistent identifiers (e.g. Handles). So, in the above example, the underlying object's handle is http://hdl.handle.net/1969.1/86172
Therefore, its URL should be something like: http://ui-prototype.atmire.com/handle/1969.1/86172
