Method and system for management of logical links between document elements during document interchange

摘要

A method and system for managing logical links between document components within a presentation data stream which includes a continuous ordered stream of uniquely identified data objects and associated elements. The processing of presentation form documents has been extended from hard copy devices into interactive presentation forms which accommodate sophisticated navigation techniques such as hypertext. In order to accommodate this process a link logical element (LLE) is defined within the document presentation data stream which identifies a source component and a target component for a logical link. Multiple purpose links which provide navigational linkage, annotational linkage and append linkage are provided and the link logical element further includes a field which specifies the purpose of a particular link. Optional fields are also provided which may be utilized to pass parameters to the target component upon processing the link. In this manner a receiver of the data stream may selectively process or ignore a particular logical link.
