@kayaelle - as I've defined it, `online` can either be a URI, or an array of URIs, and `physical` can either be an object containing an `address` and/or a `geo` location, or an array of said items. So I *think* we're in agreement.

As regards the existing standards, I was just suggesting we use `address`, which would be an address object as per `http://json-schema.org/address`, and `geo`, which would be a geographical object as per `http://json-schema.org/geo`, rather than @ottonomy's version. Definitely not suggesting that we only use geographical coordinates - just that we don't define our own address format when there's a standard out there already.
