一個協力方式複合文件編輯系統

Abstract

協力方式編輯系統讓身處異地的使用者可以同時編輯一份文件。複合文件 則不著痕跡地集結不同型態的資訊於一身，使得電腦文件的表達更為豐富 。協力方式複合文件編輯系統結合二者特性，支援分散式共同編輯複合文 件；每位參與編輯者均持有一份該文件的複本，以降低資料傳輸之需求。 本系統具備即時交談功能，並有相當程度的容錯設計，而並行控制與發布 通告是維繫協力編輯的重要機能。本系統所擁有的功能涵括於同一程式的 各模組中，因此維護與擴充功能時必須忍受較高的成本，卻可換得較佳的 協調能力與交換資料的便利。此外，在本文中亦討論了多使用者介面與複 合文件表現方式等相關議題，並提出我們的作法。 A collaborative editing systems allows co-authors at different locations simultaneously to edit a shared view of a single document. The compound document binds various information types to create a single seamless presentation. A collaborative compound document editing system is developed to combine both the systems described above. It supports distributed editing with replicated compound documents, and integrates notification mechanisms into concurrence control modules. The real-time conversational facilities and some degree of fault tolerant mechanisms are provided. All functionalities of the system are implemented as different modules within the same program . It endures a substantial cost in functionality, but enjoys the finer coordinating and the more convenient data exchanging capabilities. Besides, this thesis discusses the design issues such as multi-user interfaces and the presentations of compound documents, and proposes our approaches
