Method and system for management of logical links between document elements during document interchange
First Claim
1. A method of flexibly managing logical links between document components within a presentation data stream comprising a continuous ordered stream of uniquely identified data objects and associated elements, said method comprising the steps of:
- defining a link logical element structured field within said presentation data stream;
specifying within said link logical element structured field one of the following components as a source of origination for a selected logical link;
a document;
a page group;
a page;
an overlay;
a process element;
a rectangular area;
a data object;
or a non-native data object;
specifying within said link logical element structured field a target for said selected logical link; and
specifying within said link logical element structured field a particular purpose for said selected logical link among a plurality of purposes wherein said selected logical link may be selectively processed or ignored by a receiver of said presentation data stream.

Abstract
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.
