ITU-T X.660建议书 | ISO/IEC 9834-1定义了支持国际对象标识符(OID)的树形结构。它包括OID树的顶弧的注册。它还规定了国际注册机构的操作程序,可以在需要的时候由其他ITU-T建议书和/或国际标准使用。
为便于引用,并为了强调这个树属于原始OID树(定义于本建议书 | 国际标准的前期版本)的一种扩展形式,这个特定树可以被引用为“国际对象识别树”,或更常用的“OID树”。
原始OID树要求所有弧都必须单值识别为一个主整数值,用于人类可读(不一定单值)辅标识符(限定为拉丁字母)。辅标识符通常不是以协议形式承载或用于机器识别符。国际对象标识符树此进行了扩展,允许一个弧可被一个Unicode符号(一个Unicode字符串)进行单值识别,而后者可以以协议形式承载并用于机器识别。
国际对象标识符主整数和辅标识符继续用于ASN.1 OBJECT IDENTIFIER类型的编码(仅主整数值)和数值计数(主整数值和辅标识符),这一点没有变化。Unicode符号只能用于ASN.1 OID-IRI类型的编码和数值计数。
本建议书 | 国际标准也提供了有关较低级别弧的适当收费结构建议。 |
