Foreword
ISO (the International Organization for Standardization) is a worldwide federation of national standards bodies (ISO
member bodies). The work of preparing International Standards is normally carried out through ISO technical
committees. Each member body interested in a subject for which a technical committee has been established has the right
to be represented on that committee. International organizations, governmental and non-governmental, in liaison with
ISO, also take part in the work. ISO collaborates closely with the International Electrotechnical Commission (IEC) on all
matters of electrotechnical standardization.
International Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 2.
The main task of technical committees is to prepare International Standards. Draft International Standards adopted by the
technical committees are circulated to the member bodies for voting. Publication as an International Standard requires
approval by at least 75 % of the member bodies casting a vote.
Attention is drawn to the possibility that some of the elements of this document may be the subject of patent rights. ISO
shall not be held responsible for identifying any or all such patent rights.
ISO/IEC 19500-3 was prepared by Technical Committee ISO/IEC JTC1, Information technology, in collaboration with the
Object Management Group (OMG), following the submission and processing as a Publicly Available Specification (PAS)
of the OMG Common Object Request Broker Architecture (CORBA) specification Part 3 Version 3.1 CORBA
Components.
ISO/IEC 19500-3 is related to:
• ITU-T Recommendation X.902 (1995) | ISO/IEC 10746-2:1996, Information Technology - Open Distributed
Processing - Reference Model: Foundations
• ITU-T Recommendation X.903 (1995) | ISO/IEC 10746-3:1996, Information Technology - Open Distributed

CORBA Interfaces
• ISO/IEC 19500-3, Information Technology - Open Distributed Processing - CORBA Specification Part 2:
CORBA Interoperability
ISO/IEC 19500 consists of the following parts, under the general title Information technology - Open distributed
processing - CORBA specification:
• Part 1: CORBA Interfaces
• Part 2: CORBA Interoperability
• Part 3: CORBA Components

It is the common core of the CORBA specification. Optional parts of CORBA, such as mappings to particular
programming languages, Real-time CORBA extensions, and the minimum CORBA profile for embedded systems are
documented in the other specifications that together comprise the complete CORBA specification. Please visit the
CORBA download page at http://www.omg.org/technology/documents/corba_spec_catalog.htm to find the complete
CORBA specification set.
Apart from this Foreword, the text of this International Standard is identical with that for the OMG specification for
CORBA, v3.1.1, Part 3.

Introduction
The rapid growth of distributed processing has led to a need for a coordinating framework for this standardization and
ITU-T Recommendations X.901-904 | ISO/IEC 10746, the Reference Model of Open Distributed Processing (RM-ODP)
provides such a framework. It defines an architecture within which support of distribution, interoperability and portability
can be integrated.
RM-ODP Part 2 (ISO/IEC 10746-2) defines the foundational concepts and modeling framework for describing distributed
systems. The scopes and objectives of the RM-ODP Part 2 and the UML, while related, are not the same and, in a number
of cases, the RM-ODP Part 2 and the UML specification use the same term for concepts which are related but not
identical (e.g., interface). Nevertheless, a specification using the Part 2 modeling concepts can be expressed using UML
with appropriate extensions (using stereotypes, tags, and constraints).
RM-ODP Part 3 (ISO/IEC 10746-3) specifies a generic architecture of open distributed systems, expressed using the
foundational concepts and framework defined in Part 2. Given the relation between UML as a modeling language and Part
3 of the RM-ODP standard, it is easy to show that UML is suitable as a notation for the individual viewpoint
specifications defined by the RM-ODP.
This part of ISO/IEC 19500 (CORBA Components) is a standard for the technology specification of an ODP system. It
defines a technology to provide the infrastructure required to support functional distribution of an ODP system, specifying
functions required to manage physical distribution, communications, processing and storage, and the roles of different
technology objects in supporting those functions.
