| 摘要: |
| 论述了基于Dexter超文本标准模型的协同超媒体系统的通用体系结构设计中的问题。该结构包括开发与Dexter兼容的超媒体系统的通用框架。其中的编辑进程、客户进程和OODB服务器进程分别对应于Dexter模型的各个层。OODB提供了灵活的锁定和通告机制,这些机制使得OODB更为通用且可独立于基于Dexter的进程和数据模型而有所变化和扩展。文章最后给出了一些协同系统使用的典型例子。 |

| Abstract: |
| Issues for the design of a general architecture for cooperative hypermedia systems based onthe Dexter Hypertext Reference Model have been discussed. The architecture includes a generic framework for developing bexter-Compatible hypermedia systems.In the frame-work,the Editor process,Client process and OODB server process be designed correspond to the layers proposed by the Dextermodel seperately.The OODB provides support for flexible locking and event notification mechanism.Developing such support within the OODB makes it general and independent of changes and extensionsto the Dexter-based process and data models.At last,some examples of abstract use of scenarios aregiven. |
