XML技术在森林资源数据交换平台中的应用研究

A research of XML technology application for the forest resource data-exchanging platform

我国的森林资源数据具有异构性、分布性和孤立性等特点,这极大地制约了森林资源数据的共享、交换以及联合应用。在数字林业平台基础上,基于XML技术开发的森林资源数据交换平台为解决异构数据的交换和共享作了有效尝试。论文首先介绍了森林资源数据交换平台的结构及其运行模式,然后以森林资源规划设计调查数据交换为例讨论了XML在平台中的应用:(1)运用XML Schema定义森林资源数据交换标准;(2)采用标准的XML格式进行数据交换;(3)采用XML的描述转换语言XSLT进行数据格式转换,实现数据交换和共享。

The forest resource data are featured with heterogeneity, distribution and isolation, which largely restrict sharing, exchanging and associated application of the forest resource data. In order to solve the problem of heterogeneous data exchanging and sharing, the XML technologies have been effectively used to develop the Digital Forestry Platform based forest resource data- exchanging platform. This paper firstly introduced the architecture and running model of the forest resource data- exchanging platform, then took the forest resource planning and design survey data exchanging as an example to discuss how to apply XML technologies, including （1） applying XML Schema to define forest resource data exchanging standard; （2） adopting unified XML format to exchange data; （3） Using XSLT to transform data format for data exchanging and sharing.
