Sequence diagram for the personalized itinerary search
The data models that the service should exchange with the PS are defined (see
Figure 3.8).
A request specifies the username of the user (DN) and the data (
Departure
,
Arrival
,
ArrivalTime
, etc.) for the itinerary search. A response (
Response
) takes the
request (with the DN) and adds all the possible itineraries (
Result
).
This response is associated with a choice (
Choice
), which enables the itinerary
likely to interest the user to be referenced. An itinerary (
Result
) is made up of
several ways (
Way
) and includes its own characteristics (
Criteria
).
