Store and track countless xAPI activities.
Watershed allows you to store and track unlimited xAPI activities—such as taking a quiz, filling out a survey, or watching a video.
Keep in mind, an activity isn’t the same thing as a data source or learning record provider. For example, a learning record provider provider might be an LMS that contains hundreds of courses made up of thousands of slides. And it's those courses and slides that result in unique activities.
