文章设计并实现了一种企业门户框架。该框架设计了具有对象属性粒度的控制机制和权限管理,提出了符合Web特性的对象元数据模型,并以组织、人员角色、数据对象、权限、频道以及工作流6个核心元素为组件,将非结构化信息和结构化信息管理、控制和发布统一起来,从而能够方便地根据企业复杂多变的信息需求对系统进行扩展,在Web平台上快速部署符合企业个性的信息系统。

For constructing their portals on enterprises＇ intranet effectively, a framework, which is based on object-based and weboriented information model, fine-grained right model and channel-based information publishing, is proposed in this paper. The framework consists of six basic elements： role, organize, resource, right, workflow and channel. By customizing the six elements with enterprisespecific data and consolidating distributed data source with data gateway, enterprises can build enterprise-dedicated portal systems quickly and cost effectively. Beyond these ideas, a framework named after EPortal-I is developed. Its implementation in enterprises proves our points.
