SmartCom Digital System of Units (D-SI) Guide for the use of the metadata-format used in metrology for the easy-to-use, safe, harmonised and unambiguous digital transfer of metrological data - Second Edition (SmartCom数字国际单位制(D-SI):促进便捷、安全、协调、明确的计量数据数字化传输的计量元数据格式使用指南-第二版中文版)

This guide specifies principles for determining the use of units in digitised communication of machine-readable data. These principles form the basis for all applications that transmit or require measurement data according to the specifications of the Système International d'Unités (SI). Basic principles for harmonised, clear, easy to understand and secure digital communication of metrological data are defined for real, complex, vector and constant quantities.

The metadata model described is essential for the exchange of metrological information in all fields of Information and Communication Technologies (ICT). In terms of content, the model takes into account essential international metrology guidelines and standards. For the first time, in conjunction with the globally established SI, measures are defined which are essential for an easy, secure, harmonised and unambiguous exchange of metrological data. The handling of non-SI units and the requirements for conversion between SI and non-SI quantities are taken into account.

In addition, a classification for the suitability of metrological data for interoperability and machine readability is made (medal system). The classification results from the use of SI units as defined in the 9th edition of BIPM's SI brochure.

Finally, this guide is the second edition of "SmartCom Digital System of Units (D-SI) Guide for the use of the metadata-format used in metrology for the easy-to-use, safe, harmonised and unambiguous digital transfer of metrological data". It adds a comprehensive appendix with rules for using the D-SI and an improved reference to the XML implementation for the D-SI.

本指南规定了在机器可读数据的数字化通信中确定单位使用的原则。根据国际单位制(SI)的规范,这些原则构成了所有传输或需要测量数据的应用程序的基础。定义了协调、清晰、易于理解和安全的计量数据数字通信的基本原则,包括实数量、复数量、矢/向量和常量/数。

所述元数据模型对于在信息和通信技术(ICT)所有领域的计量信息交换是基础性的。就内容而言,本模型考虑了基本的国际计量准则和标准。这是第一次,与全球建立的SI一起,定义了对于简单、安全、协调和明确的计量数据交换至关重要的原则。非SI单位的处理以及SI量和非SI量之间转换的要求也被考虑在内。

此外,还对用于互操作性和机器可读性的计量数据的适用性进行了分类(奖牌系统)。分类结果是使用了第9版BIPM 的《SI手册》中定义的SI单位。

最后,本指南是第二版《SmartCom数字国际单位制(D-SI) 促进便捷、安全、协调、明确的计量数据数字化传输的计量元数据格式使用指南》。它添加了一个全面的附录,其中包括使用D-SI的规则,以及对D-SI的XML实现的改进参考。
