Abstract

The document management systems or modules generally have their unique requirements for the document formats and or the information that are stored for the management of documents. Because of the above requirements, the prior art document management systems or modules fail to exchange or share the documents. The document management systems and modules of the current invention overcome the above difficulties by converting the document data requirements from one system to another. The conversion includes a predetermined set of procedures where certain data is added, deleted or modified so that the documents are compatible among the document management systems, units or modules.
