* 'short' includes 'mini' plus address information, start and end date, otherconnections, userfollow.
* 'long' includes 'short' and associated website objects, tag objects, group onjects, votes, view counts and extra properties.
* 'full' includes 'long' and all activity and voting data. This is likely to be very heavy. Use wisely.
* 'shortactivity' includes 'short' plus the activity and voting data.
* 'cif' just what is needed for cif.
