Media logging is the process of describing student interactions with media, both within and outside of tutored activities, using the Tutor Message format.

This section of the guide describes this standard form for logging media events using the Tutor Message framework. It assumes you are familiar with the tutor message format, described in Section 2, “The Tutor Message format”.

3.1. Similarity between media logging and tutor logging

In media logging, the existing message types—the context, tool, and tutor messages—are used to describe user interactions with media objects.

Similar to logging in which no media objects are present, tool and tutor messages are always preceded by a context message. The entire series of messages is also contained in a single element, the <tutor_related_message_sequence>. But unlike logging in which no media is present, media logs are composed primarily of tool messages; tutor messages are only required when a media event is explicitly tutored.
