Foreword
ISO (the International Organization for Standardization) and IEC (the International
Electrotechnical Commission) form the - specialized System for worldwide
standardization. National bodies that are members of ISO 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. ISO and
IEC technical committees collaborate in fieldsof mutual interest. Other international
organizations, governmental and non-governmental, in liaison with ISO and IEC, also
take part in the work.
In the field of information technology, ISO and IEC have established a joint technical
committee, lSO/lEC JTCI. In addition to developing International Standards, lSO/IEC
JTCI 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,ProfiIe requires approval by at least 75%
of the national bodies casting a vote,
International Standardized Profile ISO/IEC .ISP 11185-6 was prepared with the
collaboration of
- OSI Asia-Oceania Workshop (AOW);
- European Workshop for Open Systems (EWOS);
- Open Systems Environment Implementors Workshop (OMI).

Introduction
This International Standardized Profile lSO/IEC ISP 11185 is defined within the context
of Functional Standardization, in accordance with the principles specified in lSO/IEC
TR 10000, crFramework 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 (OSI) Standard ISO 9040 for the Virtual Terminal
Basic Class Service identifies a requirement for an International Register of VT Control
Object type definitions. Procedures for the Operation of this International Register are
laid down in ISO/IEC 9834-5. This International Standardized Profile provides this
register. 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 ISO/IEC ISP 11185 was developed in close cooperation between the three
Regional OSI Workshops, namely the OSE Implementors Workshop (OMI) of the
United States, the European Workshop for Open Systems (EWOS) and the OSI Asia-
Oceania Workshop (AOW). lt was developed under the editorship of EWOS from a
control Object specification contained in the European S-mode Forms Functional
Standard of ENV 41 208. The text is harmonized between these three Workshops and
it has been ratified by the plenary assemblies of each Workshop.
