Full Title

ISO/IEC 9834-8: Information Technology - Open Systems Interconnection - Procedures for the Operation of OSI Registration Authorities: Generation and Registration of Universally Unique Identifiers (UUIDs) and Their Use as ASN.1 Object Identifier Components


ISO/IEC 9834-8 specifies the format and rules for the generation of 16 octet (128 bit) identifiers suitable for use as either transient or persistent Universally Unique Identifiers (UUIDs). Also known as Globally Unique Identifiers (GUIDs), these are guaranteed to be unique, or extremely likely to be different, depending on the generation method chosen. The standard identifies procedures for a Web-based registration authority for universally unique identifiers and specifies how to use them as a URN or an ASN.1 Object Identifier (OID).
