| 摘 要： | 文章系统介绍了国际地学信息管理与应用委员会(CGI)的主要数据标准:地球科学标记语言GeoSciML、地球资源标记语言EarthResourceML及地学专业术语Geoscience Terminology等。采用UML的包和类图方式简要介绍了GeoSciML、EarthResourceML的构成模式、建模方法和谱系图,以列表形式概览了支持多国语言语义的地学专业术语库。重点介绍基础数据包中的地质单元、构造、地貌要素和地质事件等核心要素,矿床数据包中与采矿等有关的活动要素,以及矿点数据包中的矿产资源、矿床类型、成矿模型等。并基于GeoSciML标准初步设计了一个地质数据模型,采用EarthResourceML标准设计了一个矿业权模型,验证地学数据模型之间通过动态关联可生成若干新要素的优势,为开展国际地学大数据转换等提供了技术参考。

| Abstract: | The paper introduces the International Commission for Geoscience Information of IUGS (CGI) and its main standards on geoscience markup language GeoSciML, Earth resource markup language EarthResourceML, and the vocabulary of Geoscience Terminology. Modeling method and pedigree chart of GeoSciML have been briefly introduced. Modelling theories, methods and structures of GeoSciML and EarthResourceML have been described by using package diagrams and class diagrams of UML, and the multi-language
vocabulary is listed. Geologic Unit, Geologic Structure, Geomorphologic Feature and Geologic Event of GeoSciML Basic package are presented as the main focus. So as the two main packages of EarthResourceML, Mineral package and Mineral Occurrence package. The former package containsmany classes related to activities in the mining process, and the MO package describes factors independent from human activity, such as mineral resources, deposit types, and mineralization models. Inspired by the thorough investigation, a primary geological data model based on GeoSciML and a mining rights data model based on EarthResourceML are proposed. They offer good solutions to discover new geologic features by exploring dynamic relations between different geoscience data model, and provide excellent references to geoscience data sharing. |
