Attribute Exchange Extension

If your service requires more extensive user profile details than those provided by the Simple Registration process, Attribute Exchange may be the right mechanism for your needs. Support for the extension and (if it is supported) the specific attribute types available will depend on your particular provider. More details are available at the following websites:

In addition to the standard types, which we will discuss in the next few sections, there are several experimental types: http://www.axschema.org/types/experimental/.

Attribute exchange types: Addresses

The first category of Attribute Exchange types we will look at is address types. The AX extension defines a number of address identifiers for a default address (such as a home or personal shipping location) and a business address, as shown in Table 11-4.
