Address and Phone
Addresses, phone numbers and so forth
TODO: Does this need changing in light of this public-lod thread?
The vCard namespace (usually shortened to the prefix 'v:') provides a general way to describe contact details, which can be applied to both organisations and places.
You should use v:adr to associate an address with any of: a person, organisation, organisational unit, or a spatial thing such as a room, building or site.
Note that an organisation's address is where to direct post, whereas that of a place refers to its physical location. Thus, a unit and its primary site may quite legitimately have different addresses.
An address is composed of the following parts to be reconstructed in the given order:
- vcard:extended-address (e.g. *The Example Building**)
- vcard:street-address (e.g. **Old Kent Road**)
- vcard:locality (e.g. **London**)
- vcard:postal-code (e.g. **EX1 1EX**)
- vcard:country-name (e.g. **United Kingdom**)
You can omit unwanted parts as necessary.
Address have the type vcard:Address and are related to their subject by the v:adr property:

(the above example has embedded the address inside the org description to make it easier to read. You could omit the rdf:about which ends with "#address" but in general it's tidy to give everything an identifier, and for people, places and organisations adding "#address" to the end of their URI is a reasonable way to create a URI for their address.
In the UK it is strongly suggested that you provide a link to the postcode URI for buildings, the URIs for which are published and resolved by the Ordnance Survey.
