标准摘要
[中文适用范围]： 本文档提供了在指定 ITS 国际标准中使用的数据类型时实现 ASN.1 使用一致性的正式方法。 这样做的目的是确保明确且可互操作的数据交换，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引用并在某些情况下指定附加规则来提高标准之间的一致性，以确保一致的解释。 除了以通用且灵活的形式提供数据类型定义之外，本文档不需要使用 ASN.1 进行任何其他操作。 本文件对支持以下内容做出了具体规定： ——嵌入其他现有的标准化编码格式，例如 jpg，同时保持 ITS 内的互操作性和重用； ——允许数据类型定义的替代表示，例如 XML 模式； ——允许定义数据的替代编码。 本文档中提出的规则使数据类型能够以通用且一致的形式记录在通用 ITS 数据注册表和 ITS 国际标准中。 [外文原描述]： 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.
