Re: Categorization + Whether a POI must have location

The location is the identification of how to place the POI, its not
necessarily a static co-ordinate.

The location could, for example, be specified by a RFID that could
move with the object.
Or, for example, by image recognition - the clients check the camera
feed against some data that represents the identifiable points of an
object. (You'd need to consult image recognition specialists for what
exactly that data is)

There needs to be a location specified, but we should certainly leave
many different types of location parameters as options for what that
could be.
