A block of flats will also have many addresses. Each individual apartment will have its own. If there is a garage down the street which is part of the "property" of the flat, you could say that the garage is also part of the address. Things can get very messy...
Depending on the definition you choose, an address may be 1-dimensional, 2-dimensional or 3-dimensional. Although the majority of cases are 1:1 (a house with one address) we need a scheme that is able to handle the esoteric cases as well. Buildings with no address, buildings with multiple addresses, addresses with multiple buildings, addresses with an extreme extent, apparent duplicate addresses etc etc. Any scheme which cannot handle these cases is IMHO broken (or to use a nicer word: incomplete). In IT-land it is very usual to allow a location to have multiple addresses, each with a "role". For example, you may have one address for post (PO Box number), one for putting in your satnav for visiting by car, one "round the back" for goods deliveries - all referring to the same building. The local government may have yet another idea. //colin On 2015-05-27 09:47, Martin Koppenhoefer wrote: >> Am 27.05.2015 um 09:38 schrieb Jean-Marc Liotier <j...@liotier.org>: Absent >> any information, tagging the plot is better than nothing.
