中文摘要：

针对由于快递物流快件跟踪信息的数据异构所导致数据信息共享、服务互操作实现难度增加的问题，建立了快递物流跟踪信息数据字典和数据模型，基于可扩展标记语言（extensiblemarkuplanguage，XML）提出了一种易于扩展的快递物流跟踪信息标记语言（markuplanguageforexpresslogisticstracinginformation，ELTIML），并设计了ELTIML的模式schmea；最后，对四家快递公司快件跟踪信息查询系统提供的跟踪信息异构问题，以快递物流跟踪信息标记语言描述数据交换文档建立应用框架。结果表明，以ELTIML语言为基础的数据交换模式能屏蔽数据源的异构，是实现数据交换的有效手段。

英文摘要：

Due to the tracing information heterogeneous in the basic express item, the data heterogeneous would result in diffi- cult to share information and interoperate searching service. This paper introduced XML to describe data and analyzed data ex- change mode of tracing information of express logistics, the data dictionary was draw up first, and then put forward a data de- scribe language based on XML, which was ELTIML（ markup language for express logistics tracing information） , and proposed a schema of ELTIML. At last, with regard to tracing information heterogeneous in four express logistics information management system, it designed an information tracing application framework using ELTIML. The results indicates that data exchanging model based on ELTIML shields heterogeneity of data resources and it is a efficient method of data exchange.
