Abstract

In a compound document data stream allowing for the interchange of resource objects, text, graphics, image and the like, as well as resource data such as fonts and color tables, a function permitting indirect referencing of resources from within the data stream is provided. A unique coded identifier, which must be mapped to the name of the resource prior to being used as a reference to the resource, is the chosen implementation method. Prior art systems allow resources to be referenced by using a system assigned identifier. Typically, these systems support a specific type of resource, such as a coded font resource used by a word processing application or a color table resource manipulated by a graphics application, and therefore, have no problem with resource type identification.

Method of Specifying Referenced Resource Object Name and Type

In a compound document data stream allowing for the interchange of resource objects, text, graphics, image and the like, as well as resource data such as fonts and color tables, a function permitting indirect referencing of resources from within the data stream is provided. A unique coded identifier, which must be mapped to the name of the resource prior to being used as a reference to the resource, is the chosen implementation method. Prior art systems allow resources to be referenced by using a system assigned identifier. Typically, these systems support a specific type of resource, such as a coded font resource used by a word processing application or a color table resource manipulated by a graphics application, and therefore, have no problem with resource type identification. If multiple resource types are required within a single application, a separate identification function uniquely addressing the resource type is the method most commonly chosen to address this need. Requiring a separate identification function for each resource type within a compound document data stream would result in undue operator frustration and a loss of processing efficiency, because of the excessive number of unique identification functions that would have to be provided for each resource type that could be included in the data stream. A method providing for both resource identification and specification of type in a single function is what is required.

To facilitate efficient processing of references in a compound document data stream, a Resource Local Identifier triplet, which identifies a required resource by type, is p...
