我们提出了一个分层的组件模型，以支持基于Web的协同应用。我们展示了这种模型如何让程序员专注于他们的应用程序的特定逻辑，避免了大多数与协作，访问控制和网络管理相关的问题。所提出的模型被组织成三层的基础上，由商业现成的服务和标准的互联网协议。服务级别提供了一个网络透明的通信层、数据库访问和分布式数据交换。组件级提供典型的协作服务，如用户管理、审计、面向用户的消息传递、更高级别的事件、项目管理和公告板。应用程序层支持使用底层提供的服务构建的实际应用程序。在此框架上开发了一个基于Web的教育应用程序来说明该过程。这一远程教育系统遵循了参与学习技术标准化进程的主要机构的建议，是作者提出的第二个贡献。
We present a layered component model to support Web-based collaborative applications. We show how this model lets programmers focus on the particular logic of their applications, avoiding most of the issues related to collaboration, access control, and network management. The proposed model is organized into three layers on top of a foundation composed of commercial-off-the-shelf services and standard Internet protocols. The service level provides a network-transparent communications layer, database access, and distributed data interchange. The component level offers typical collaborative services, like user management, auditing, user-oriented messaging, higher-level events, project management, and a bulletin board. The application level supports actual applications constructed using the services offered by the underlying layers. A Web-based educational application has been developed over this framework to illustrate the process. This tele-education system, which follows the recommendations of the main institutions involved in the learning technology standardization process, is the second contribution presented by the authors.
