基于XML的岩芯信息元数据标准研究与实践

目前岩芯信息表述尚没有统一的格式,严重阻碍了岩芯信息资源的利用,造成了资源浪费。为提高岩芯信息利用率,方便用户和其他软件共享岩芯信息,必须规范其组织、存储和交换数据格式,并提供相应的技术实现手段通过软件自动保存、解析岩芯信息。文章参照国内外相关资料及技术标准,创建了岩芯信息元数据标准,应用XML技术生成与元数据标准对应的XSD文件,并在应用程序中成功使用,当用户交互岩芯信息时,生成符合XSD格式要求的XML数据文件传送信息,不同用户可以正确解析岩芯信息。通过应用岩芯信息元数据标准,规范了数字化岩芯信息组织、存储和交换,采用XML技术由软件自动实现,大大提高了用户工作效率,方便了岩芯信息的共享,充分发挥了岩芯信息的价值。

Metadata Standardization and Application for Core Information Based on XML

Due to the lack of a unified presentation format, the resource for core information is clearly under-utilized at present. To improve the utilization of core information, as well as facilitating the sharing of information among users and other softwares, the format should be standardized for organization, storage and data exchange. Relative technologies are being developed for auto-storage, interpretation and analysis of core information via software. Referring to the relative reference materials and technique standards worldwide, the authors created the standards of metadata for core information. XML technology can be used to create the XSD regarding to respective metadata standards, which has been implemented successfully in application programs. Using the XML data file generated by corresponding XSD, different users can interpret the core information correctly during interaction. With metadata standardization for core information, the organization, storage and data exchange format can be normalized automatically via software using XML technology. Results show an improvement in the efficiency of users, facilitated information by sharing, and enhanced the utilization of core information.
