lSO/IEC ISP 10607-2 : 1995 (E)
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 or 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,
ISO/IEC JTCI. In addition to developing International Standards, ISO/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 Profile requires approval by at least 75 % of the national bodies
casting a vote.
International Standardized Profile ISO/IEC ISP 10607-2 was prepared with the collaboration of
- Asia-Oceania Workshop (AOW);
- European Workshop for Open Systems (EWOS);
- Open Systems Environment Implementors’ Workshop (OIW).
ISO/IEC ISP 10607 consists of the following parts, under the general title information technology
- International Standardized Profiles AFTnn - File Transfer, Access and Management :
- Part I: Specification of ACSE, Presentation and Session protocols for the
use by RAM
- Part 2 : Definition of document types, constraint sets and syntaxes
- Par? 3 : AFT1 I - Simple File Transfer Service (unstructured)
- Part 4 : AFT12 - Positional File Transfer Service (flat)
- Part 5 : AR22 - Positional File Access Service (flat)
- Part 6 : AFT3 - File Management Service
This second edition cancels and replaces the first edition (ISO/IEC ISP 10607-2:1990), which has
been revised. It also incorporates amendment 1: 1991 and amendment 2:1994.
Annexes A, B and C of this part of ISO/lEC ISP 10607 are for information only.

lSO/IEC ISP 10607-2 : 1995 (E)
Introduction
This part-of ISO/IEC ISP 10607 is defined within the context of Functional Standardization,
in accordance with the principles specified by lSO/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. A profile defines a combination of base standards that collectively perform a
specific well-defined IT function. Profiles standardize the use of options and other
variations in the base standards, and provide a basis for the development of uniform,
internationally recognized system tests.
One of the most important roles for an ISP is to serve as the basis for the development (by
organizations other than IS0 and IEC) of internationally recognized tests and test centres.
ISPs are produced not simply to legitimize a particular choice of base standards and
options, but to promote real system interoperability. The development and widespread
acceptance of tests based on this and other ISPs is crucial to the successful realization of
this goal.
The text for this part of ISO/IEC ISP 10607 was developed in close co-operation among the
FTAM Expert Groups of the three International OSVOSE Workshops : OSE Implementors’
Workshop (OIW), the European Workshop for Open Systems (EWOS) and the Asia-
Oceania Workshop (AOW). This part of lSO/IEC ISP 10607 is harmonized among these
three Workshops and it was finally ratified by the Workshops’ plenary assemblies.
