Fully understand it but if you check the toString() output it
concatenates both ;) Which from what you later explain I understand.

That's what I meant ;) I finally explained myself

I'm getting this data from a Webservice and I wanted to parse it. But I
have just realized that maybe it is the webservice the one that should
be doing it by properly returning the URI. In the webservice is where
the model is managed.
