ISO 14813-6:2017提供了实现ASN使用一致性的正式方法。1在指定国际标准中使用的数据类型时。这是为了确保数据交换的明确性和互操作性，同时提供这些交换的一致文档。本文件提供了必要的规范，通过提供对多个标准的正式参考，并在某些情况下规定了额外的规则，以促进标准之间更大的一致性，从而确保解释的一致性。 ISO 14813-6:2017不要求使用ASN。1用于以通用灵活的形式提供数据类型定义以外的任何内容。本文件对以下方面的支持做出了具体规定: -嵌入其他现存的标准化编码格式，例如。 g、 jpg，同时保持其内部的互操作性和重用性； -允许数据类型定义的替代表示，例如XML模式； -允许对定义的数据进行替代编码。 本文件中的规则使数据类型能够以一种通用且一致的形式记录在ITS数据注册中心及其国际标准中。

ISO 14813-6:2017 provides a formal means to achieve consistency in the use of ASN.1 when specifying data types that are to be used in ITS International Standards. This is designed to ensure unambiguous and interoperable data exchange while providing consistent documentation of these exchanges. This document provides the necessary specifications to ensure consistent interpretation by providing formal references to several standards and in some cases specifying additional rules to promote greater consistency among standards. ISO 14813-6:2017 does not require the use of ASN.1 for anything other than providing data type definitions in a common and flexible form. This document makes specific provision for the support of: - Embedding other extant standardised encoding formats, e.g. jpg, while maintaining interoperability and reuse within ITS; - Allowing alternative representations of data type definitions, e.g. XML schema; - Allowing alternative encoding of defined data. The rules presented in this document enable data types to be recorded in a common ITS data registry, and in ITS International Standards, in a common and consistent form.
