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
