Managing topics

Topics are subjects that a subscriber chooses to receive (subscribe to). Specific messages can be associated with topics; messages with similar contents are published to a topic, and subscribers register for the topic. This ensures that they will receive all relevant messages.

The following is an example of a Topics Summary View:

Summary view operations available from the Operations drop-down menu are: Copy As New Topic, Delete, Permissions, Audit, Publish Messages, Upload/Import, Tag Topic

To access the selected topic's Properties Editor, click the Topic Name. 

In addition, the following operations are available from the operations drop-down menu in the main options bar:

• New Topic: Create a new topic.
• Publish Messages: Publish a topic message.
• Upload/Import: Upload/import messages to topics.
• Show Topic Status: Switch to the Topic Status Summary View.
• CSV Export: Exports the information displayed in this view in CVS format.
