针对数字图书馆环境下如何进行信息资源建设、实现信息资源共享的问题,从面向对象的角度出发将UML与XML结合起来,提出一种使用UML建模创建XMLSchema元数据的方法。通过该方法建立的元数据可使信息资源表达更加有效,语义更加清晰和便于交流,有利于数字图书馆信息资源的共建共享。 Aiming at the problem of how to construct the information resources in the digital library environment and realize the sharing of information resources, UML and XML are combined from the perspective of object-oriented to propose a method to create XML Schema metadata using UML modeling. The metadata established by this method can make the expression of information resources more effective, semantic more clear and easy to communicate, which is beneficial to the co-construction and sharing of digital library information resources.
