FRAMEWORK FOR ENERGY MARKET COMMUNICATIONS –

Part 501: General guidelines for use of ebXML


FOREWORD
1) The International Electrotechnical Commission (IEC) is a worldwide organization for standardization comprising
all national electrotechnical committees (IEC National Committees). The object of IEC is to promote
international co-operation on all questions concerning standardization in the electrical and electronic fields. To
this end and in addition to other activities, IEC publishes International Standards, Technical Specifications,
Technical Reports, Publicly Available Specifications (PAS) and Guides (hereafter referred to as “IEC
Publication(s)”). Their preparation is entrusted to technical committees; any IEC National Committee interested
in the subject dealt with may participate in this preparatory work. International, governmental and non-
governmental organizations liaising with the IEC also participate in this preparation. IEC collaborates closely
with the International Organization for Standardization (ISO) in accordance with conditions determined by
agreement between the two organizations.
2) The formal decisions or agreements of IEC on technical matters express, as nearly as possible, an international
consensus of opinion on the relevant subjects since each technical committee has representation from all
interested IEC National Committees.
3) IEC Publications have the form of recommendations for international use and are accepted by IEC National
Committees in that sense. While all reasonable efforts are made to ensure that the technical content of IEC
Publications is accurate, IEC cannot be held responsible for the way in which they are used or for any
misinterpretation by any end user.
4) In order to promote international uniformity, IEC National Committees undertake to apply IEC Publications
transparently to the maximum extent possible in their national and regional publications. Any divergence
between any IEC Publication and the corresponding national or regional publication shall be clearly indicated in
the latter.
5) IEC provides no marking procedure to indicate its approval and cannot be rendered responsible for any
equipment declared to be in conformity with an IEC Publication.
6) All users should ensure that they have the latest edition of this publication.
7) No liability shall attach to IEC or its directors, employees, servants or agents including individual experts and
members of its technical committees and IEC National Committees for any personal injury, property damage or
other damage of any nature whatsoever, whether direct or indirect, or for costs (including legal fees) and
expenses arising out of the publication, use of, or reliance upon, this IEC Publication or any other IEC
Publications.
8) Attention is drawn to the Normative references cited in this publication. Use of the referenced publications is
indispensable for the correct application of this publication.
9) Attention is drawn to the possibility that some of the elements of this IEC Publication may be the subject of
patent rights. IEC shall not be held responsible for identifying any or all such patent rights.
The main task of IEC technical committees is to prepare International Standards. However, a
technical committee may propose the publication of a technical report when it has collected
data of a different kind from that which is normally published as an International Standard, for
example "state of the art".
IEC 62325-501, which is a technical report, has been prepared by IEC technical committee
57: Power systems management and associated information exchange.
The IEC 62325 series cancels and replaces IEC 62195 (2000) and its amendment (2002).
It constitutes a technical revision.
IEC 62195 (2000) dealt with deregulated energy market communications at an early stage. Its
amendment 1 (2002) points out important technological advancements which make it possible
to use modern internet technologies based on XML for e-business in energy markets as an
alternative to traditional EDI with EDIFACT and X12. The new IEC 62325 framework series for
energy market communications currently consisting of IEC 62325-101, IEC 62325-102,
IEC 62325-501, and IEC 62325-502 follows this direction and replaces IEC 62195 together
with its amendment.

INTRODUCTION
With the transition of monopoly energy supply structures to deregulated energy markets, the
function of the markets depends heavily on seamless e-business communication between
market participants. Compared with global e-business, e-business in the energy market is
only a small niche. Today EDIFACT or X12 messages, or proprietary HTML and XML
solutions based on Internet technologies are being used.
The ‘electronic business Extensible Markup Language’ (ebXML) specification and architecture
stems from UN/CEFACT and OASIS (see www.ebXML.org). The technical parts regarding the
technical e-business infrastructure have now become the multipart ISO 15000 series
“Electronic business eXtensible Markup Language (ebXML)” being complemented in future to
cover all technical aspects of ebXML. ebXML is a complete set of specifications and
standards to enable secure electronic business using proven, open standards such as
TCP/IP, HTTP, SOAP, XML, and SOAP signature and encryption. ebXML is also evolutionary
in nature, built on 25 years of EDI experience, designed to work with existing EDI solutions, or
be used to develop an emerging class of internet-based electronic business applications
based on XML. This means that existing EDI messages (EDIFACT, and X12) as well as XML
messages can be exchanged.

4 Generic technical architecture
4.1 General
The following text is mainly based on the public description of the ebXML initiative
(http://www.ebxml.org/) and is intended to provide a basic understanding of the technology.
For details, refer to the ebXML implementation framework specification and the ebXML
architecture document of the initiative.
4.2 Architecture
4.2.1 General
The vision of ebXML is to create a single global electronic marketplace where enterprises of
any size and in any geographical location can meet and conduct business with each other
through the exchange of XML based messages. ebXML is a complete set of specifications to
enable secure, global, electronic business using proven, open standards such as TCP/IP,
HTTP, SOAP, and XML. ebXML is also evolutionary in nature, built on 25 years of EDI
experience, designed to work with existing EDI solutions, or be used to develop an emerging
class of internet based electronic business applications based on XML.
Since systems integration and software interoperability are the cornerstones of any successful
IT infrastructure, ebXML is built on an infrastructure that ensures electronic interoperability.
This is accomplished by providing an open semantics framework that allows enterprises to
find each other, agree to become trading partners, and conduct business. The evolution of
many new business models will be enabled by ebXML, through business process patterns and
the 'commoditization' of such business processes.
The electronic business infrastructure provided by ebXML is broad in scope and well
integrated. And perhaps most importantly, ebXML is platform and vendor neutral, providing an
industry solution based on open standards, designed through a collaborative and open
process.
ebXML is a set of specifications that together enable a modular, yet complete electronic
business framework for using the Internet. The ebXML architecture provides:
ƒ A way to define business processes and their associated messages and content.
ƒ A way to register and discover business process sequences with related message
exchanges.

---------------------- Page: 11 ----------------------

oSIST-TP IEC/TR 62325-501:2009
– 10 – TR 62325-501  IEC:2005(E)
ƒ A way to define company profiles.
ƒ A way to define trading partner agreements.
ƒ A uniform message transport layer.
The ebXML framework is designed for electronic interoperability, allowing businesses to find
each other, agree to become trading partners and conduct business. All of these operations
can be performed automatically, minimising, and in most cases completely eliminating the
need for human intervention. This streamlines electronic business through a low cost, open,
standard mechanism.
In order for enterprises to conduct electronic business with each other, they should:
ƒ Discover each other and the products and services they have to offer.
ƒ Determine which shared business processes, and associated document exchanges, to use
for obtaining products or services from each other.
ƒ Determine the contact points and form of communication for the exchange of information.
ƒ Agree on the contractual terms on the above chosen processes and associated
information.
ƒ They can then: exchange information and services in an automated fashion in accordance
with these agreements.
ebXML is designed to meet these needs and is built on three basic concepts: provide an
infrastructure that ensures data communication interoperability; provide a semantics
framework that ensures commercial interoperability; and provide a mechanism that allows
enterprises to find each other, agree to become trading partners and conduct business with
each other. The infrastructure to ensure data communication interoperability is provided
through:
ƒ A standard message transport mechanism with a well defined interface, packaging rules,
and a predictable delivery and security model.
ƒ A 'business service interface' that handles incoming and outgoing messages at either end
of the transport.
ƒ A semantic framework to ensure commercial interoperability is provided through a meta
model for defining business process and information models.
ƒ A set of re-useable business logic based on core components that reflect common
business processes and XML vocabularies.
ƒ A process for defining actual message structures and definitions as they relate to the
activities in the Business Process model.
ƒ A mechanism to allow enterprises to find each other, agree to establish business
relationships, and conduct business, is provided through shared repository where
enterprises can register and discover each other's business services via partner profile
information.
ƒ A process for defining and agreeing to a formal Collaboration Protocol Agreement (CPA),
if so desired or where required.
ƒ A shared repository for company profiles, business process models and related message
structures.
The ebXML implementation framework defines the ebXML Technical Architecture. The
technical architecture is composed of five main area of emphasis: Business Process and
Information Model, Collaboration Protocol Profiles Company Profiles, Messaging Services,
Registry and Repository, Collaborative Partner Agreements.

4.2.2 Business process description
The Business Process models define how business processes are described. Business
Processes represent the "verbs" of electronic business and can be represented using
modelling tools. The specification for business process definition enables an organisation to
express its business processes so that they are understandable to other organisations. This
enables the integration of business processes within a company, or between companies.
Figure 1 shows the graphical presentation of the BPSS (Business Process Specification
Schema) process specification to provide a basic understanding of the technology. The main
elements are multiparty collaborations and binary collaborations. Both include (reference)
business transactions, which govern the business document flow.


IEC  150/05
Figure 1 – Process specification
Figure 2 shows the graphical presentation of the business transaction from the Business
Process Specification Schema (BPSS).
The business transaction consists of a requesting business activity and a responding
business activity each associated with a document envelope (which includes the business
documents and attachments).

IEC  151/05
Figure 2 – Business transaction
Figure 3 shows the graphical presentation of the binary collaboration from the Business
Process Specification Schema (BPSS). Specific business process specifications are derived
from the UML activity diagram (see IEC 62325-502). The Business Process Specification
Instance uses the BPSS and is, besides the CPP/CPA, the most innovative part of ebXML.
BPSS, CPP/CPP are shared between business partners and are used for both documentation
and system configuration.
The binary collaboration is between two business partners with one partner in the initiating
role and the other partner in the responding role. It includes business transaction activities
and (nested) collaboration activities. These activities reference business transactions
respective collaborations. Collaborations have a start state (Start) and a completion state
(Success or Failure). From start to end there can be pseudo-states fork (Fork) and join (Join)
for parallel transactions. The transition state specifies that a given activity be followed by
another activity.

Figure 3 – Binary collaboration
Figure 4 shows the graphical presentation of the multiparty collaboration from the Business
Process Specification Schema (BPSS). The multiparty collaboration is between more that two
partners and consists of multiple binary collaborations. It is defined by the business partner’s
role, which performs (Performs) one or more roles in various binary collaborations.
Transitions (Transition) can be added to define the transition from one business transaction
activity to the other.
