Abstract
A user-level controlled mechanism is interposed into a read/write path of a computer system. The mechanism can be implemented as properties attached to documents. Documents having properties attached thereto have the capability of separating the content of the document from the properties which describe the document. This separation of the document content from its properties allows for a user-level access and control of the properties thereby allowing a user flexibility in organizing, storing and retrieving documents. The mechanism allows a user to arrange collections of documents wherein a single document may appear in multiple collections. The properties of the present invention are user and document specific in the sense that they are associated with the user which attached the properties and are directed to control of specific documents.
