1. A system for creating a dynamic folder hierarchy, comprising: a network; a host server connected to said network via a communications link; and a computer in communication with said network wherein said computer including a processor capable of executing instructions comprising: creating a design-time folder group definition specifying an organization of a hierarchy of design-time folder groups with each design-time folder group consisting of a plurality of design-time folders arranged in parent-child relationships, said definition including a set of variable binding expressions for associating a plurality of documents with a plurality of dynamic folders; generating a query with predicates from said set of variable binding expressions; searching a collection of documents to identify documents which match said query, each of said documents in said collection of documents containing self-describing data; dynamically creating a hierarchy of dynamic folders including child dynamic folders within said hierarchy of design-time folder groups by using a combination of said design-time folder groups definition and said identified documents; and associating each of said identified documents with at least one dynamic folder in said hierarchy of dynamic folders.

The system of claim 1 , further comprising generating additional dynamic folder hierarchies, each of which associates a collection of documents wherein overlapping occurs between said dynamic folder hierarchies.
