The Comments From LMS data model element is made up of three elements. These elements can be used to track different characteristics about a specific comment or annotation. The elements are:
- Comment - The actual textual content associated with the Sharable Content Object (SCO)
- Location - The point in a SCO to which the comment applies (if there is no location, then the comment is applicable to the whole SCO)
- Timestamp - A point in time at which the comment was created or recently changed
