Abstract: Systems and methods for controlling the dissemination of data from a repository based on the substitution of content contained within a generated response. The systems and methods are used by the repository to allow for the transfer of data that is not known or anticipated until the time of an access. For each access whose intent is to provide data to the repository or to retrieve variable data held by the repository, the repository uses the systems and methods to manage novel information structures whose purpose is to facilitate the substitution of the variable portions of content and to apply a privilege value to the portions that are variable. Using the concept of a “notational fragment”, the systems and methods are capable of assembling a variable result that has interaction with a data source.

Abstract: Systems and methods for controlling the dissemination of data from a repository based on request mechanisms that are transparent to the requestor and the connection conveying the requests. The systems and methods are used by the repository to enforce one or more rule sets that implement varying levels of access privilege created by the repository designer. For each user requesting access to privileged data, the repository uses the systems and methods to manage novel information structures whose purpose is to apply the rule sets to the requestor's session. By incorporating into each request, a set of values herein named a “forresta” and a “destination”, the systems and methods exercise control over data access, assemblage and presentation. In addition, the systems and methods provide that clients require no enhancements to well-known methods or systems used to facilitate communications with repositories employing this invention.
