+For jobs, the app data typically contains the information needed to display
+the job to a user - e.g., the name of an image file.
+For calibration jobs, it would also contain the correct answer.
 
-For each application and each user,
-Bossa maintains ''skill estimate'', an estimate of the user's skill at that task.
-This is maintained in the user's database record.
-Normally it's a single number in [0..1], and it's initially zero.
+For instances, the app data typically contains the user's response to the job.
 
-The skill estimate can be computed in any of several ways:
+For users, the app data typically contains a representation of the
+user's "skill", possibly including:
 
- * The results of the user's interaction with a Bolt course associated with the application.
- * The user's performance on "calibration jobs" mixed into the stream.
- * The fraction of the user's results classified as invalid by redundancy.
+ * their score on a training course
+ * their performance on calibration tasks
+ * their performance based on validation
 
-Skill estimates are used for two purposes:
+If a project has multiple applications, it should keep separate
+data for each applications.
 
- * To decide whether to give jobs to a user;
- * To decide how many redundant instances of a given job are needed.
