本文探讨了数字图书馆(DL)开发生命周期中应给予关注的几个问题。开发者须熟悉系统内容及用户需求以开发出有用的 DL;通过维护系统品质及其易访问性来保证系统的持久可用性;使用导航模块等工具技术确保系统对大多数用户能简易省时地使用;保证系统的开放性是为了接纳潜在的用户群体,也使得系统易于适应变化的运行环境和技术更新;在确保系统使用的信息资料和技术方法不侵犯他人权利的同时,还需控制用户访问权限。 This article explores several issues that should be of interest in the DL development life cycle. Developers must be familiar with system content and user needs to develop useful DLs; maintain long-term system availability by maintaining system quality and accessibility; and use tools and tools such as navigation modules to make the system easy and time-saving for most users ; To ensure the openness of the system is to accept potential user groups, but also make the system easy to adapt to changing operating environment and technology updates; to ensure that the system uses information and technical methods do not infringe upon the rights of others, but also control user access .
