Abstract

Data Objects appearing in an interchange document can be defined once and referenced multiple times. This eliminates respecification of a data object that is used repeatedly within the document. A resource data object is distinguished from a composition data object by the containing Begin/End envelope and its semantic context (e.g., a data object in a page that is currently being interpreted is NOT a resource data object).

A Method for Characterizing the Processing Mode of Data Objects Resource or Inline Composition Objects

Data Objects appearing in an interchange document can be defined once and referenced multiple times. This eliminates respecification of a data object that is used repeatedly within the document. A resource data object is distinguished from a composition data object by the containing Begin/End envelope and its semantic context (e.g., a data object in a page that is currently being interpreted is NOT a resource data object).

The specification of data objects (text, image, graphics, etc.) within the scope of a resource group permits these data objects to be transmitted as part of the data stream and to be subsequently referenced. Data objects that exist between a Begin/End Resource Group specification do not become "activated" as a document composition entity until that data object is "referenced" within the context of a page, segment, nesting data object, or the like that is currently being processed. By encapsulating data objects in a Begin/End Resource Group specification, the processor of the data stream understands that such data objects are simply members of an "inline library" which may or may not become activated. Conversely, a data object encapsulated in a Begin/End envelope that is currently being interpreted is part of an active document composition construct.

One advantage of this invention is that data objects used multiple times in a document need onl...
