Figure P.03 - Party Identification

As well as being having names for Parties, we also need more formal ways of identification [Coad Letter]. When a customer applies for a service, for instance, they may need to provide some proof of identity. The Party Identification entities allow for this information to be stored and accessed as required.
Note that the Party Identification structure has been defined in a similar manner to Party Name.
Concrete subclasses to Individual Identification and Organization Identification should be created as required. Figure 3 shows some common example concrete entities.
The Party Identification Specification entity may be implemented as a Policy, using a Rules Engine or via a set of Templates that detail a valid set of Identification entries sufficient for a given purpose.
