| 摘 要： | 数字对象按被使用时的表现形态可分为四大类:静态文档对象、流媒体对象、复合数字对象和交互式对象,不同的数字对象对应着不同的传输形式,这一特点决定了数字对象需要不同类型的服务器;在对象服务器内部 ,数字对象的命名体系和寻址方式决定了服务器的可维护性和可扩充性,文章给出了一个零维护解决方案;数字对象的打包和传输方式影响着客户的使用质量和为此付出的成本,本文同时给出了一个文档对象的打包形式和传输方式;最后说明了一个数字对象服务器的实现

| Abstract: | Digital objects can be classified by their modals presented when being applied into four kinds: static document object, stream-media object, combined digital object and interactive object. Different kinds of digital objects have different kinds of transmission modals, which determines that they need different kinds of servers;Inside the object server,the identity system and search method of digital object determine the maintainability and expandability. This paper puts forward a solution of zero maintainability;The package and transmission mode of digital object will influence the usage quality and costs .This paper puts forward a package and transmission mode of documents. At last,this paper sets forth a realization of digital objects server.. |
