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
to deal with particular fields of technical activity. IS0 and IEC
established by the respective organization
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, ISOiIEC
JTC 1. Draft International Standards adopted by the joint technical committee are circulated to national
bodies for voting. Publication as an International Standard requires approval by at least 75 % of the national
bodies casting a vote.
International Standard ISOiIEC 10740-2 was prepared by Joint Technical Committee ISOiIEC JTC 1,
Information technology, Subcommittee SC 18, Document processing and related communication.
ISOiIEC 10740 consists of the following parts, under the general title Information technology - Text and ofice
systems -Referenced Data Transfer:
- Part 1: Abstract service definition
- Part 2: Protocol specification.
hex A of this part of ISOiIEC is for information only.

Introduction
This International Standard is one of a set of standards for distributed-office-applications which define
abstract services and specify acccess protocols in accordance with the Application Layer of the Open
Systems Interconnection (OSI) Reference Model (IS0 7498).
Distributed-office-applications are used by an integrated distributed office system, consisting of user
nodes and server nodes linked by a network. The user nodes access the server nodes via the network,
using access protocols.
In such an environment, data processing applications that within a single host act as a single piece, have
been split among the different intelligent components of the system. This splitting has led to the need for
standardization of inter-relationships between the different parts of an application.
In this environment the distributed-office-applications should satisfy the following objectives:
- Make easier the implementation of application-processes developed for a distributed
environment based on micro-processors and large or medium sized mainframes
interconnected through local area network or wide area network means;
-
Reduce the processing delay time for document related activities such as document filing and
retrieval, document distribution, printing, etc.;
-
Allow concurrent processing of different tasks within the distributed office system;
-
Reduce the overall size of an office system and facilitate its modular extension.
Within distributed-office-applications, there will be applications that will act as Accessees or Accessors of
objects whose values are of comparatively large size, for example files, documents or body parts. ISO/IEC
10031-1 the Distributed-office-applications model, contains a functional model for these cases named
Referenced Object Access (ROA). According to this model, the transfer of data-object-values conceptually
involves three parties: an Initiator which requests the transfer, an Accessee which produces the data-
object-value and an Accessor which consumes the data-object-value. To achieve economies in the use of
transmission facilities and hence more efficient use of system resources, a mechanism is required
whereby an Accessee can provide an Initiator with a reference to a data-object-value. This reference can
then be given by the Initiator to the Accessor which can then contact the Accessee directly for example to
obtain the data-object-value. This mechanism is known as the ROA. It provides a way to perform ROA-
operations between an open-ended list of parties.
This Part of ISO/IEC 10740 describes the RDT protocol, a realization of the RDT abstract service as
defined in ISO/IEC 10740-1. The RDT protocol realization takes the form of an RDT Application Service
Element (ASE) and two RDT Application Contexts (ACs), together with conformance requirements for
implementations.

1 Scope
This Part of ISOAEC 10740 describes the application-service-element (ASE) and the application-contexts
distributed-office-applications. Its content covers four
(ACs) for the Referenced Data Transfer within
major areas:
-
An introductory part in which references, definitions and abbreviations are collected
together.
-
Specification of the RDT Application Service Element (RDTSE).
-
Specification of two RDT Application Contexts containing the RDTSE.
-
Conformance requirements for the RDT Application Contexts.
