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.
