Foreword
IS0 (the International Organization for Standardization) and IEC (the International
Electrotechnical Commission) form the specialized system for worldwide
standardization. National bodies that are members of IS0 or IEC participate in the
development of International Standards through technical committees established by
the respective organization to deal with particular fields of technical activity. IS0 and
IEC technical committees collaborate in fields of mutual interest. Other international
organizations, governmental and non-governmental, in liaison with IS0 and IEC, also
take part in the work.
In the field of information technology, IS0 and IEC have established a joint technical
committee, lSO/IEC JTC 1. In addition to developing International Standards, lSO/IEC
JTC 1 has created a Special Group on Functional Standardization for the elaboration
of International Standardized Profiles.
An International Standardized Profile is an internationally agreed, harmonized document
which identifies a standard or group of standards, together with options and
parameters, necessary to accomplish a function or set of functions.
Draft International Standardized Profiles are circulated to national bodies for voting.
Publication as an International Standardized Profile requires approval by at least 75%
of the national bodies casting a vote.
International Standardized Profile lSO/IEC ISP 11186-4 was prepared with the
collaboration of
- OSI Asia-Oceania Workshop (AOW);
- European Workshop for Open Systems (EWOS);
- Open Systems Environment Implementors’ Workshop (OIW).

Introduction
lSO/lEC ISP 11186 is defined within the context of Functional Standardization, in
accordance with the principles specified in ISO/IEC TR 10000, “Framework and
Taxonomy of International Standardized Profiles ”. The context of Functional
Standardization is one part of the overall field of Information Technology (IT)
standardization activities, covering base standards, profiles and registration
mechanisms.
The Open Systems Interconnection (0%) Standard IS0 9040 for the Virtual Terminal
Basic Class Service provides for the identification of attribute assignment types by
means of ASN.1 object identifiers. This International Standardized Profile provides a
means for the registration of such attribute assignment type definitions in accordance
with ISO/IEC 9834-l. The individual entries in this register constitute Interchange
Format and Representation Profiles (F-Profiles) within the framework of lSO/lEC
TR 10000.
This part of lSO/lEC ISP 11186 was developed in close cooperation between the three
Regional OSI Workshops, namely the OSE Implementors Workshop (OIW) of the
United States, the European Workshop for Open Systems (EWOS) and the OSI Asia-
Oceania Workshop (AOW). The text is harmonized between these three Workshops
and it has been ratified by the plenary assemblies of each Workshop.
