Adding Multimedia Extensions to Existing Applications

The ToolTalk Document and Media Exchange Message Set also allows an application to use other multimedia applications to extend its features or capabilities. For example, a Calendar Manager can be extended to use the Audio Tool to play a sound file as a reminder of an appointment, as illustrated in the following scenario:

1. Shelby opens her Calendar Manager and sets an appointment.

2. Shelby clicks on an Audio Response button, which causes the Audio Tool to start.

3. Shelby records her message; for example, "Bring the report."

When Shelby's appointment reminder is executed, the Calendar Manager will start the Audio Tool and play Shelby's recorded reminder.
