Documentation management is a crucial component of successful business-related projects, but it often involves significant effort in terms of time and cost. Initializing, writing, and revising project documents can be a monotonous and fragmented task, especially during rapid project development. However, the context among most project documentation and business administration is highly interconnected. Based on the relationships among project documentation, especially for multimedia projects, this study uses the concept of section-orientation and presents a cooperative mechanism that uses object technology to clarify project documentation and its context. This study also introduces a prototype object-based functional project documentation system and illustrates the mechanism through two case studies and data analysis. The purpose of this study is to present a definite expression of this context in functional project documents. The results are practically applicable for managing multimedia project documentation.
