At the same time , it will promote actively the sharing and network issue of geo - spatial information . it also has far - reaching social meaning . at last , we apply the register of the system designed by us to fgdc 最后我们将所设计的空间信息元数据管理系统向fgdc申请注册，并且将该节点发布到internet上，任何单位和个人都可以通过www浏览器访问我们的元数据。
Therefore , i was quite disappointed to see so many of the xml process initiatives reinvent the rdf wheel . but as i noted in a developerworks article the web services description language wsdl , all too many xml applications overlook rdf s strengths 它能帮助人们了解半结构化关系和元数据管理的价值，因此这简直是恩赐，因为向生意人甚至许多开发人员解释这一概念都不是一件容易的事。
So , we depicted the content management system from different aspects , and pointed out the core issues about metadata management , xml interface form , and process management and etc . we also gave an instance of cms to explain the concepts above 文章据此对相关的内容管理系统进行了刻画，并通过对一个影像系统实例的分析，指出了其中诸如元数据管理， xml接口形式，流程管理等关键的核心议题。
