The catalog lists the topics in a grid format. You can drill down on each topic to view general details about the topic, the topic structure, a list of publishers to the topic, and a list of subscribers to the topic.

You can perform a free text search to find topics in the catalog or search for topics based on topic tags.

You can subscribe to a specific topic from the catalog. When you subscribe to a topic from the catalog, the subscription wizard appears. You then create a subscription in the same way that you create a subscription directly from the application. After you subscribe to a topic from the catalog, the subscription appears in the subscribers list for the topic and in the subscription list for the application.

You can open topics from the catalog for editing if the associated publications and subscriptions are not running.
