Looking
Back and Ahead: CECID's Competency in
E-Commerce Standardization |
|
To build an e-commerce software infrastructure
that enhances the capability of Hong Kong government
and business enterprises to conduct electronic
business locally and
globally, there are
three dimensions of interoperability
that need to be achieved. They are messaging
interoperability, business information interoperability,
and business process interoperability. CECID
is gradually
extending its technology focus from business
connectivity to business process engine and
further to
business
information and process modeling tools.
CECID has focused on addressing the messaging
interoperability by developing standardized
messaging frameworks that enable secure and
reliable exchange of electronic documents
between
different enterprise applications for conducting
business. Based on ebXML, CECID has developed
essential ebXML architectural components such
as ebXML message service handler, Hermes,
for business documents to exchange in a secure
manner. Besides ebXML, the R&D team is
now developing Hermes 2 to support other messaging
standards, such as AS2
and Web Services.

After enabling business documents to exchange
securely, CECID works on TranXnet,
which is a generic business process execution
engine governing the document exchange sequence
among the applications. It provides not only
an execution platform for both external B2B
application, but also internal workflow application
or EAI. Partners involving in an e-business
activity develop applications to interface
with
TranXnet to exchange electronic documents.
Before a business process is started, business
partners
first define the business process as XML standards,
e.g. Business Process Specification Schema
(BPSS)
in the ebXML domain, Business Process Execution
Language for Web Services (BPEL4WS).
Since November, CECID has proceeded to address
the business information and process interoperability
on the Internet. The new R&D initiatives
involve standardization on the contents of
electronic
documents to be exchanged for conducting business,
as well as standardization on business process
that governs the document exchange sequences
for conducting business. The development of
Business
Information Modeling (BIM) Tool and Business
Process Modeling (BPM) Tool, aimed to
achieve the business information and process
interoperability
respectively, is underway. These tools will
support the process-driven, standards-based
paradigm on XML and Web Services. This in turn
brings benefits to organizations by enabling
movement of business information smoothly within
the organization and between the organization
and its suppliers/customers via EAI and B2B
integration. BIM and BPM tools
are expected
to complete by May 2006.

Thematic
Interoperability Frameworks
Interoperability - the ability of
two or more systems or components to
exchange information and to use the
information that has been exchanged.
IEEE Standard Computer Dictionary:
A Compilation of IEEE Standard Computer
Glossaries.
New York, NY: 1990
The above definition implies at least
two aspects need to be addressed by systems
or components in order to be interoperable
- technical interoperability and semantic
interoperability. Technical interoperability
can be achieved by using standards or
'standards-based' protocols. Semantic
interoperability is concerned with the
definition and understanding of data for
exchange and reuse.
Interoperability frameworks are collections
of technical and data specifications
that
define the interface between interacting
applications. Frameworks of different
focuses or themes have been developed
to address the technical and semantic
aspects. For example, OASIS/UNCEFACT's
ebXML
framework focuses on messaging,
semantics, processes and modeling technical
standards,
while several economies, Australia,
European
Union (EU), Hong
Kong, and United
Kingdom, have developed interoperability
frameworks for e-government initiatives.
Spearheaded by EAN.UCC, an organization
dedicated to standards development for
universal product codes (or simply known
as bar codes), Global
Data Synchronization Network,
aims to help retailers and manufacturers
to synchronize product data. There are
beliefs that global data synchronization
is a necessary building block to RFID
(radio frequency identification) implementation.
Besides these frameworks, some industry
consortiums
have defined
vertical frameworks (or models) for their
industries. RosettaNet is
one such model catered to the high
tech products supply chain. Frameworks
mentioned above may not cover the
same focus or scope; nevertheless, one
denominator
they often advocate is openness:
open standards, open systems interconnection,
open architecture, or the use of
open
source software. For a comparison
of open
standards and open source, refer
to CECID's
June 2004 newsletter.

MTRC Staff Movement Data Synchronization Process
Project
In an enterprise, data are collected by disparate
systems and need to be synchronized across
systems
to ensure data consistency. At MTRC, the major
subway operator in Hong Kong, employment records
are frequently updated in the Human Resources
Management System (HRMS) and Corporation Qualification
Administration System (CQA). The data are then
sent to several other systems at MTRC. To
simplify
and standardize MTRC's staff movement data
synchronization process, CECID will provide
an EAI solution.
In this new pilot project with MTRC, data in
source systems (HRMS and CQA) are synchronized
with two critical systems, Engineering
Traffic Management System (ETMS) and Operation
Publication
Distribution System (OPDS). The aim of this
project is to improve the extensibility and
flexibility of the current staff movement data
synchronization process by using XML and Web
Services standards.
From time to time, after employees join MTRC,
their personal profile, job function, and/or
employment
status, demographic data and employment details
need to be created or updated in the HRMS
and
CQA, and these data are supposed to be automatically
synchronized with other systems to keep data
up-to-date and consistent among systems. However,
the existing interfaces between the HRMS/CQA,
and the other systems are lack of standardized
techniques and technologies for data exchange.
To achieve interoperability, this project first
defines data file in a more flexible XML format.
After defining a standard data structure, a
new centralized EAI architecture is proposed
and Web Services technology is introduced to
replace FTP as the data transfer protocol.
This
integration platform provides reliable messaging
and data consistency across different systems.
The first phase of the project is on
synchronization between CQA, ETMS and OPDS.
The deployment has been done in August,
and now the system is under pilot testing.
This
phase
should
be put into production in late 2004. The second
phase will start in Q1 2005 which will put
HRMS in the picture and aim at enhancing the
reliability, extensibility and usability of
the system.
