ABSTRACT:
Systems and methods for managing a plurality of electronically stored documents in an open document repository employ a one-way hash function to compute a hash for the stored documents as an indexing link. A document management index maps an attribute of an original document stored in the repository to the hash and the document. A hash-to-location index maps the hash to an address location of the document in a file system of the repository. The attribute points to the hash which then points to the location for linking the attribute to the location.
