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 fields of 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, ISO/IEC JTC 1. In
addition to developing International Standards, ISO/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 a 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 15125-12 was prepared with the collaboration of
— Asia-Oceania Workshop (AOW);
— European Workshop for Open Systems (EWOS);
— Open Systems Environment Implementors' Workshop (OIW).

Introduction
The concept and structure of International Standardized Profiles for Information Systems are laid down in the
Technical Report ISO/IEC TR 10000. The purpose of an International Standardized Profile is to recommend when
and how certain information technology standards shall be used.
The International Standardized Profile, ISO/IEC ISP 15125, consists of a set of International Standardized Profile
parts relating to the Directory as defined in the Technical Report ISO/IEC TR 10000-2.
This part of ISO/IEC ISP 15125 specifies application profile ADY53 (see TR 10000-2) which defines six functional
subsets that may be supported by Directory System Agent (DSA) implementations when shadowing Directory
information in accordance with ISO/IEC 9594-9:1995 | ITU-T Recommendation X.525:1993.

specified in terms of a unit of replication. A DSA which

provides a unit of replication is termed a 'shadow supplier';
a DSA which receives a unit of replication is termed a

The Directory standards specify a directory information
shadowing service which DSAs may support in order to
replicate Directory information. This shadowing service

information can be set up and maintained between co-
operating DSAs. The information to be shadowed is
specified in terms of a unit of replication.
DSA DSA
This part of ISO/IEC ISP 15125 defines a number of
DISP
functional shadowing subsets to which a DSA
implementation may conform. Each functional subset
requires a DSA to be capable of performing shadowing to a
particular level, this level being based upon the degree of
Shadow Shadow
refinement permitted within the specification of a unit of

replication. The functional subsets can be related to either
a DSA implementation operating as a supplier of shadowed
information or a DSA implementation acting as a consumer
of shadowed information.
= Unit of Replication
This part of ISO/IEC ISP 15125 identifies the capability to
handle overlapping replicated areas specified within
different units of replication as a separate, optional
capability which a DSA implementation may combine with
