Coordinates is a mix-in class which is used to store elementary
coordinates of an Entity (ex. Person, Organisation)
UNKNOWN Coordinates are treated as a document
with a subject (to find a given type of coordinate).
Coordinates use a URL approach. Any coordinate can
be rendered in a URL style. For example::
- tel:+33(0)662057614
- fax:+33(0)153010929
- mailto:jp@nexedi.com
- naf:722Z
- smail://Nexedi/Jean-Paul Smets/943, av de la Republique/59700
Marcq-en-Baroeul/France
Coordinates are stored as content within an Entity. Coordinate ids
are generated as a combination of a so-called role (ex. shipping,
billing, etc.) and a class string. This way, coordinates can
be accessed as attributes of the containing Entity::
- default_phone
- default_fax
- billing_address
- shipping_address
In order to be able to list all coordinates of an Entity,
a list of Coordinate metatypes has to be defined and
stored somewhere. (TODO)
