Abstract
A system and method for categorizing objects on the basis of the existence of the facts describing those objects. Objects may be stored in the collection regardless of their category, and each object may have any number of facts associated with it. The objects are then categorized on the basis of their data structure, that is, on the basis of the existence of the facts associated with that object.
