Mode is the data model element that identifies one of three possible modes in which the Sharable Content Object (SCO) may be presented to the learner: browse, normal or review. These values can be used to indicate the SCO's behavior after launch. Many SCOs have a single behavior, but some SCOs can present different amounts of information. The information can be presented in different sequences, it can reflect different training strategies or store different sets of data based on the mode the SCO is currently in.
