RFC 3061 OID URN Namespace February 2001 2. Specification Template Namespace ID: "oid" requested. Registration Information: Registration Version Number: 1 Registration Date: 2000-04-30 Declared registrant of the namespace: The ISO/IEC Joint Technical Committee 1 - SubCommittee 6 The real authority is the ASN.1 specification itself but SC6 is the committee that has the authority to interpret what that means, thus that committee is listed as the registrant. Declaration of structure: The NSS portion of the identifier is based on the string encoding rules found in RFC 1778 Section 2.15 [4] which specifies a series of digits separated by a period with the most significant digit being at the left and the least significant being at the right. At no time shall the NSS portion of the URN contain the human readable description of a particular node in the OID tree. The NSS portion of the name is strictly limited to the digits 0-9 and the '.' character with no leading zeros. No other characters are permitted. This is all expressed in the following ABNF: oid = number *( DOT number ) number = DIGIT / ( LEADDIGIT 1*DIGIT ) LEADDIGIT = %x31-39 ; 1-9 DIGIT = %x30 / LEADDIGIT ; 0-9 DOT = %x2E ; period No changes are anticipated since Object Identifiers are fairly simple and have been standardized with no changes for many years. Relevant ancillary documentation: Relevant documentation can be found in X.660/Amd 2 | ISO/IEC 9834-1/Amd 2[3]. Mealling Informational
