Do they belong in the same thing. Some of those things are invariant - they relate to the lesson. Others relate to the user view of the lesson, and vary by user and maybe device. Why is everything a string or long? Is a position or duration measured in frames, seconds or millis? A duration could be a... Duration? Consider a microtype to avoid mixing up lesson ids and class ids? Data and Metadata usually best avoided in names as doesn't give any information.. separating this into two things might help figuring out what the names should be. Or might not! Good luck!
