as the VE. All the other entries in the Parking List are then associated to the VE.
By so doing one can, for instance, include more attributes in future version of
the PBL system.

In the following we define each of the three attributes and discuss their
decomposition:

 License plate number

o attributeName: License plate number;

o attributeType: Car information;

o Description: It is a common attribute for both VEs. In essence,

it is a numerical and alphabetical registration identifier that

officially and uniquely identifies the car within an issuing region

such as the entire country or entire state;

o Values: A resident-parker or a time-parker may own and may

have parked more than one car on the street. Therefore, it is

necessary that this attribute has one or more Values, each one

containing the License plate number of a registered car. The

example in Figure 75 states the registration of two license plate

numbers: ―M CJ 1234‖ and ―M JW 5678‖.

 Parking zone

o attributeName: Parking zone;

o attributeType: Parking information;

o Description: It is a common attribute for both VEs. This

attribute identifies the parking zone, where this car is allowed

to park;

o Value: corresponds to the name or the identifier of a parking

zone. The example in Figure 75 fig: guidelines  concrete

architecture  Information Model of the VE for resident-parker

and time-parkers] depicts the registration Zone A.

 Parker type

o attributeName: Parker type;

o attributeType: Parking information;

o Description: It is an exclusive attribute in the VE of a resident-

parker. This attribute identifies the time during which, this car is

allowed to park. Currently we differentiate between a full time

parker (24/7) and a night parker (12/7);
