Notes
Time Calculation
The group revisited its discussion of Time calculation.
- The AU calculates duration for statements it makes.
- The LMS can calculate duration for the Abandoned Statement based on statement timestamps.
- The AU can accumulate durations across sessions in it own state documents. Possibly a best practice?
- Adding aggregate times (durations) to statements was generally viewed unfavorably as the data can be derived by collecting the data from statements.
- In general, having the AU fetch xAPI statements (to calculate total time or for other purposed) would not be good practice.
- Adding launch Mode (to contexts) in Launched and Terminated statements would be useful for time aggregation in the various modes (Abandoned already has Launch Mode context)
- Adding Values to LMS.launchData for an AU's aggregate session durations (in a user registration) in each of the modes would be useful for the AU. (The LMS would aggregate the times and write the following values LMS.launchData prior to AU launch)
- Total Duration in Review Mode
- Total Duration in Browse Mode
- Total Duration in Normal Mode
Session Voiding
The discussion around time calculation also spawn a discussion around Statement Voiding and "Session Voiding". The group will review the cmi5 spec for its language on statement voiding and discuss how "Session Voiding" might be done.
