Mealling +Request for Comments: 3061 Verisign +Category: Informational February 2001 +Obsoletes: 3001 + + + A URN Namespace of Object Identifiers + +Status of this Memo + + This memo provides information for the Internet community. It does + not specify an Internet standard of any kind. Distribution of this + memo is unlimited. + +Copyright Notice + + Copyright (C) The Internet Society (2001). All Rights Reserved. + +Abstract + + This document describes a Uniform Resource Name (URN) namespace that + contains Object Identifiers (OIDs). It obsoletes RFC 3001. + +1. Introduction + + An Object Identifier is a tree of nodes where each node is simply a + sequence of digits. The rules roughly state that once an entity is + assigned a node in the Object Identifier (OID) tree, it has sole + discretion to further subdelegate sub-trees off of that node. Some + examples of OIDs include: + + o 1.3.6.1 - the Internet OID + o 1.3.6.1.4.1 - IANA-assigned company OIDs, used for private MIBs + and such things + o 1.3.6.1.2.1.27 - The Applications MIB + o 0.9.2342.19200300.100.4 - Object ID's used in the directory pilot + project to identify X.500 Object Classes. Mostly defined in RFC + 1274. + + This document specifies the "oid" URN namespace [2]. This namespace + is for encoding an Object Identifier as specified in ASN.1 [3] as a + URI. RFC 3001 [1] is obsoleted by this specification. + + The namespace specification is for a formal namespace. + + + + + + + +Mealling Informational [Page 1] + +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 [Page 2] + +RFC 3061 OID URN Namespace February 2001 + + + Identifier uniqueness considerations: + + The rules for assignment of OIDs requires that each OID be unique + to the OID space and that it cannot be reassigned or reused. By + reference this URN namespace inherents those rules. + + Identifier persistence considerations: + + The rules concerning the use of OIDs requires that they not be + reused once assigned. By reference this URN namespace inherents + those rules. + + Process of identifier assignment: + + Once an OID is assigned to some entity, that entity can then + create and assign new OIDs below that particular OID. There are + multiple entities that assign new OIDs to the general public. The + top three levels are pre-assigned as follows: + + 0 - ITU-T assigned + 1 - ISO assigned + 2 - Joint ISO/ITU-T assignment + + several assigned OIDs that are of importance to the Internet are: + + 1.3.6.1 - the Internet OID + 1.3.6.1.4.1 - IANA-assigned company OIDs, used for private + MIBs and such things + + Process of identifier resolution: + + At this time no resolution mechanism is defined. + + Rules for Lexical Equivalence: + + OIDs are composed of multiple occurrences of digits and the "." + character. Lexical equivalence is achieved by exact string match. + + Conformance with URN Syntax: + + There are no additional characters reserved. + + Validation mechanism: + + None. + + + + + + +Mealling Informational [Page 3] + +RFC 3061 OID URN Namespace February 2001 + + + Scope: + + Global + +3.
