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 audiotool to play a sound file as a reminder of an appointment, as illustrated in the following scenario:

1. Karin opens her calendar manager and sets an appointment.

2. Karin clicks on an audio response button, which causes the soundtool to pop up.

3. Karin records her message; for example, “Bring the report.”

When Karin's appointment reminder is executed, the calendar manager will start the audiotool and play Karin's recorded reminder.
