青鸟网上构件库系统通过对可复用构件的管理,支持软件企业进行基于构件的软件开发.系统在提高开放性的同时,往往会带来安全性以及知识产权方面的问题.为了解决这些问题,在青鸟网上构件库系统中采用基于角色的访问控制机制,并将构件描述信息与构件实体区别对待.为构件库系统及其所管理的构件定义了用户、角色、权限和角色继承,满足了安全性、知识产权管理等多种需求,同时也保证了系统的效率和对复用的支持.

Jade Bird web component library system (JBWCL) can support the management of software components, thereby facilitating component-based software development in software enterprises. However, the system brings the problem of security and copyright, at the same time it improves openness. To solve these problems, the role-based access control is employed in JBWCL, and the component entity is separated from its description in this paper. The user, role, phrivilege and role hierarchy for the system and those components stored in it are defined.The mechanism meets the requirement of security and copyright,meanwhile ensure the efficency of the system and the support to reuse.
