The service behaviour shall be in accordance with the patterns detailed in the Message Exchange Patterns: Identification Guidelines. It allows for two implementations of the request-reply message exchange pattern: asynchronous and synchronous.
The OGC Web Feature Service 2.0 Interface Standard shall be used for the basic behaviour.
The typical behaviour is as follows:
* Synchronous Request/Reply
- The request message is sent from the service consumer to the service
- The service consumer remains blocked while awaiting the reply
- The service remains blocked while processing the reply
- The AIXM Basic Message, the reply message, is sent from the service to the service consumer.
* Asynchronous Request/Reply
- The request message is sent from the service consumer to the service
- The AIXM Basic Message, the reply message, is sent from the service to the service consumer.
