OID repository - Standardized NameForms


Standardized NameForms		OID standards

Each OID arc is associated with a mandatory number (used for data transfer) and an optional, recommended, identifier (for legibility). An identifier begins with a lower-case letter and is followed by letters, digits and hyphens. In the cases listed in the following table, the identifier has been standardized and can be used alone (without its associated number) in the ASN.1 notation of an OID. Standardized identifiers are defined in Rec. ITU-T X.660 | ISO/IEC 9834-1, clauses A.2.3, A.3.2, A.3.3.1 and A.4.2.
