Using SIRI

How to use example files

Request/Response & Subscribe/Publish Protocol

• SIRI supports a synchronous request/response protocol and an asynchronous subscribe/publish protocol.
• Data exchange involves a request message from a client consumer and a corresponding response message from a producer server.
• Clients can subscribe to information by sending a message with request details and sensitivity criteria to filter messages.
  • The producer server maintains subscriptions and sends messages to consumers when criteria are met.

In each of the services, you will find typical examples of requests and responses, as well as examples of subscription and publication. Examples are based on use cases
