ISO/IEC and/or ITU-T activities on registration procedures


Related Recommendations | International Standards are assigned domains by the assignment of values to arcs beneath this object identifier. Where a Recommendation | International Standard specifies the operation of an international Registration Authority it will, in general, assign the use of the arcs for which it is responsible to that authority.

The registration requirements specified in Rec. ITU-T X.666 (11/95) | ISO/IEC 9834-7:1995 correspond to the following arcs in the international OID tree:
{joint-iso-itu-t(2) registration-procedures(17) international-org-name-type(n)}.
An OID for a particular registered international organization name is:
joint-iso-itu-t(2) registration-procedures(17) international-org-name-type(n) organization-name(m)}.

Rec. ITU-T X.666 (11/95) | ISO/IEC 9834-7:1995 was superseded by a more recent version which doesn't include the following text any more:
"To register a new type of name, a new arc under the {joint-iso-itu-t(2) registration-procedures(17)} arc shall be formed. To form such an arc, this Recommendation shall be amended to include that arc, and a new annex will be added to this Recommendation if needed, for the registration procedures of such a type of a name. The addition of a new arc below the {joint-iso-itu-t(2) registration-procedures(17)} arc will be agreed jointly by ISO/IEC and the ITU."

At a meeting in September 2004, there was a concern (expressed during the "AAP ballot" of Rec. ITU-T X.660 (2004) | ISO/IEC 9834-1) over the allocation of arcs beneath {joint-iso-itu-t(2) registration-procedures(17)}. After investigation and discussion, it was recognized that this arc had been allocated jointly to Brian Wood and C.E. Young (pre-1994, probably mid-1980s). This arc appears to being used for the allocation of OIDs to identify modules appearing within the Rec. ITU-T X.660 series, and also to identify Directory attributes within that series (and possibly for other OIDs appearing within that series). It is believed that the only arcs that have been allocated beneath {joint-iso-itu-t(2) registration-procedures(17)} are arcs used for OIDs within the Rec. X.660 series | ISO/IEC 9834 multi-part standard. It is (fairly) clear that the Registration Authority for arc 17 was intended to be Rec. ITU-T X.666 | ISO/IEC 9834-7.
