FME Server notification pushes data to and from FME Server in the form of messages when an event occurs. Notification Service is based on topics around which you notify applications (or people), subscribe clients, publish messages, and have messages delivered over a supported protocol.
FME Server notification delivers notifications to clients using a push mechanism that eliminates the need to periodically check, or pull, for new information and updates.
Using FME Server notification requires the following steps:
A topic is simply a keyword that identifies the subject of a notification.
Topics are usually defined in the FME Server Web User Interface in the Topics tab. They can also be defined in a workspace using an FMEServerNotifier transformer, or when publishing a workspace to FME Server.
Publishers receive notifications from clients over a supported protocol, and deliver them to a topic.
Publishers are created in the Web User Interface in the Publications tab.
For information about supported protocols for Publishers, see Publishers.
Subscribers receive notifications from topics. In response, they deliver messages to clients over a supported protocol.
Subscribers are created in the Web User Interface in the Subscriptions tab.
For information about supported protocols for Subscribers, see Subscribers.
