信息资源目录共享方式在当前多用户差异化共享需求情况下还存在着不足.在分柝信息资源目录简单共享和用户差异化需求基础上,提出基于角色的信息资源目录共享方法.在明确信息资源目录使用对象基础上,通过对信息资源目录进行属性定义并以此建立基于角色的访问控制,实现同一信息资源目录面向多用户时的差异化共享,满足各类使用者的不同共享要求,弥补了信息资源目录简单共享的不足.%At present there are still some defects in information resource catalog sharing approaches when confronting multi-user differentiated sharing requirements.On the basis of analyzing both information resource catalog simple sharing and user differentiated requirements,the paper proposes a role-based information resource catalog sharing method.While ensuring information resource catalog objective users,by means of attribute definition with information resource catalog it establishes role-based access control to achieve the differentiated sharing of one information resource catalog for multiple users.Hence the different sharing requirements of various users are satisfied and the defects of information resource catalog simple sharing are made up.
