ISO 15889:2011定义了用于创建数据描述记录（DDR）的增强Ada子集（EAST）语言。此类DDR确保对数据的完整和准确理解，并允许以自动化方式对其进行解释。这意味着软件工具能够分析DDR并解释相关数据的格式。这允许软件从任何主机（即，与生成数据的主机不同的主机）上的数据中提取值。

ISO 15889:2011 defines the Enhanced Ada SubseT (EAST) language used to create descriptions of data called Data Description Records (DDRs). Such DDRs ensure a complete and exact understanding of the data and allow it to be interpreted in an automated fashion. This means that a software tool is able to analyse a DDR and interpret the format of the associated data. This allows the software to extract values from the data on any host machine (i.e. on a different machine from the one that produced the data).
