+== Identification of course elements ==
+
+A course can change over time.
+Elements (lessons, exercises, sets) may be added, deleted, or reordered.
+
+A student has a "context" in a course - a sequential position,
+and a set of review items.
+What if the course changes, and these items change or disappear?
+
+Each element may be given a "logical name".
+For items, this defaults to the file name.
+
+A user's sequential position is stored in the DB as the logical name
+or last item viewed.
+On continuation, Bolt looks up that item.
