Abstract

MO:DCA (A Document Data Stream Interchange Architecture) provides within its document structure the capability to reference documents, data objects, overlays, pages, etc., that exist external to the referencing document on a storage medium such as DASD (direct-access storage device). Stored with the library document(s) is a "document interchange index" that provides a "process independent" document index from which applications build "process local" DASD indexes. A document reference to one library may cause a "percolated" reference to another library as shown in the figure (a reference to library 1 causes a subsequent reference to libraries 2 and 3). The result is a network of potentially dissimilar data bases that is unified by the document index interchange layer.

Linked Interchange Indexed Document Libraries

MO:DCA (A Document Data Stream Interchange Architecture) provides within its document structure the capability to reference documents, data objects, overlays, pages, etc., that exist external to the referencing document on a storage medium such as DASD (direct-access storage device). Stored with the library document(s) is a "document interchange index" that provides a "process independent" document index from which applications build "process local" DASD indexes. A document reference to one library may cause a "percolated" reference to another library as shown in the figure (a reference to library 1 causes a subsequent reference to libraries 2 and 3). The result is a network of potentially dissimilar data bases that is unified by the document index interchange layer.

Applications build and maintain "local" indexes to these libraries needed for the actual document data access. However, changes to a document's content are reflected back to the "interchange document index" because this is the single form that is application independent.

The advantage of this invention is that a network of dissimilar "linked" document libraries can exist due to the "interchange" document index layer that is independent of process local index mechanisms and stored with the interchange document.
