Method and system for caching and referencing cached document pages utilizing a presentation data stream

摘要

A method and system for presenting a document at a presentation device utilizing a presentation data stream having a continuous ordered stream of uniquely identified data objects and associated elements which specify format and presentation parameters for each of those data objects. The data stream contains a plurality of documents, including a resource document and a presentation document, which each comprise a collection of the uniquely identified data objects and associated elements. A save object command structure is defined within a resource document within the presentation data stream. Within the save object command structure, a particular data object is identified. In response to receipt of the save object command structure at the presentation device, the particular data object is stored within storage media. Thereafter, an include saved object command structure is defined within a diverse presentation document within a presentation data stream. The particular data object is identified within the include saved object command structure. In response to receipt of the include saved object command structure at the presentation device, the particular data object is presented within the presentation document, thereby enabling a portion of the resource document stored at the presentation device to be utilized within the presentation document such that presentation efficiency is enhanced.
