Abstract

Resources may exist at various hierarchy domains (levels) within an Interchange Data Stream. Each level is defined such that the applicability scope of document resources for a given level is valid for all referencing entities existing within a particular level and for all higher level(s). Thus, common resource definitions may exist at higher document levels, maximizing the degree of resource sharing while exclusive resource definitions can be defined within a particular document hierarchy domain. Note that the lifetime of resources is determined by the lifetime of a particular document hierarchy domain (e.g., Document, Page, Data Object).

Document Resource Hierarchy

Resources may exist at various hierarchy domains (levels) within an Interchange Data Stream. Each level is defined such that the applicability scope of document resources for a given level is valid for all referencing entities existing within a particular level and for all higher level(s). Thus, common resource definitions may exist at higher document levels, maximizing the degree of resource sharing while exclusive resource definitions can be defined within a particular document hierarchy domain. Note that the lifetime of resources is determined by the lifetime of a particular document hierarchy domain (e.g., Document, Page, Data Object).

The definition of document entities, such as fonts, data objects (text, image, graphics, bar code, etc.), overlays, segments, etc., within the scope of a document Begin/End Resource Group structured field pair permits these entities to be transferred as part of an interchange data stream so they may be subsequently accessed by other data stream composition constructs (e.g., an inclusion of an image logo on selected pages, a reference to a particular font for desired text display characteristics, etc.). Resource Groups are valid at various data stream hierarchy context domains (i.e., Document, Page, Data Object) within a document. The domain at which a particular resource group is specified defines its applicability scope. For example, resources defined at the document level can be accessed by any construct within a document since the document level is the highest context domain. Resources specified at the page le...
