【摘要】 在XML数据流式转换技术的基础上,提出了一种GML文件到地理OWL文件的流式转换方法。首先通过分析GML元素到地理OWL元素的映射关系,构建元素映射转换模型,然后利用STX描述该模型,最后进行技术实现。实验表明,该方法正确、高效,对内存消耗少,适用于大数据量的GML文件到地理OWL文件的转换。更多还原

【Abstract】 Based on the XML data streaming transformation technology,a streaming transformation method is proposed for transforming GML to GeoOWL.Firstly,an element mapping transformation model is built by analyzing the mapping between GML elements and GeoOWL elements,then it is described using STX,finally the method is implemented using streaming transformation technology.Experiments show that our method is accurate,efficient and less memory is consumed,thus suitable for large GML file transformation.更多还原
