RESEARCH PAPERS

PAPER ONE: 

?A Dynamic Label Checking Approach for Information Flow Control in Web 
Services?

Zahir Tari, RMIT University, Australia
Peter Bertok, RMIT University, Australia
Dusan Simic, RMIT University, Australia

Information Flow Control (IFC) is a method of enforcing confidentiality by 
using labels, data structures for specifying security classifications. IFC 
is used in programming languages to monitor procedures in an attempt to 
detect and prevent information leakage. While it ensures greater security, 
IFC excessively restricts flow of information. This paper presents a model 
of information flow control using semi-discretionary label structures. The 
authors propose a set of rules that not only increases the flexibility of 
IFC but also defines labels as a practical component of a security system. 
The authors propose a dynamic approach using a centralized model for 
dynamic label checking and verify the proposed model using theoretical 
proofs.

PAPER TWO: 

?Service-Oriented Solution Framework for Internet Banking?

Tony Chao Shan, Wachovia Corporation, USA
Winnie Wei Hua, CTS Inc., USA

This paper describes a service-oriented solution framework designed for 
Internet banking in financial services. A pragmatic approach is developed 
to help migrate conventional n-tier e-commerce systems to a 
service-oriented computing paradigm, composed of Service-Oriented 
Architecture (SOA), Integration (SOI), Process (SOP), and Management 
(SOM). This comprehensive framework comprises Service Patterns, 
Architecture Process, Hybrid Methodology, Service-Oriented Enterprise 
Model, and Solution Platform. E-business patterns are applied to 
categorize diverse online services, which form the baseline for subsequent 
selection justifications of appropriate technologies, products/tools, and 
infrastructure. A multi-level architecture process is developed to cope 
with the architecture complexity in a disciplined way. Furthermore, a 
hybrid methodology is designed to leverage the benefits of both top-down 
and bottom-up approaches, in which a converging layer is conceived to 
incorporate the latest technologies such as portal, process orchestration, 
Web services, service aggregations, business rule engine, and so forth.

PAPER THREE: 

?Bandwidth and Latency Considerations for Efficient SOAP Messaging?

Christian Werner, University of Lübeck, Germany
Carsten Buschmann, University of Lübeck, Germany
Tobias Jäcker, University of Braunschweig, Germany
Stefan Fischer, University of Lübeck, Germany

Although Web service technology is being used in more and more distributed 
systems, its areas of application are inherently limited by high latencies 
and high amounts of protocol overhead. For messaging in environments with 
user interaction, like Web platforms for business or multimedia 
applications, the response time of the whole system needs to be kept in 
tight boundaries. In other scenarios including mobile communication and 
battery-powered devices, bandwidth-efficient communication is imperative. 
In this paper, the authors address both of these issues. First they 
conduct a detailed latency analysis of different transport mechanisms for 
SOAP and then thoroughly investigate their protocol overhead. For both 
aspects the authors present a theoretical analysis as well as experimental 
measurement results. A new transport binding called PURE is then 
introduced.

PAPER FOUR:

?Facilitating Dynamic Service Compositions by Adaptable Service 
Connectors?

Gang Li, Institute of Computing Technology, China
Yanbo Han, Institute of Computing Technology, China
Zhuofeng Zhao, Institute of Computing Technology, China
Jing Wang, Institute of Computing Technology and
Graduate School of the Chinese Academy of Sciences, China
Roland M. Wagner, Fraunhofer Institute for Software and Systems 
Engineering, Germany

Dynamic changes of services and requirements require service connection 
relationships adaptable in service compositions. This paper presents an 
adaptable service connector model and related language and tools. The 
model presents service connection relationships as an explicit component 
with which service connections can be reconfigured and changes of services 
involved in the interaction can be handled; this makes the service 
connection relationships more adaptive. With the language and tools 
supporting the model, services can be dynamically chained, which make 
service-oriented applications adapt to volatile business requirements and 
dynamic changeable services. The related case study and evaluation are 
also presented in this paper.

PAPER FIVE: 

?XML Data Services?

Vinayak Borkar, BEA Systems, Inc., USA
Michael Carey, BEA Systems, Inc., USA
Nitin Mangtani, BEA Systems, Inc., USA
Denny McKinney, BEA Systems, Inc., USA
Rahul Patel, BEA Systems, Inc., USA
Sachin Thatte, BEA Systems, Inc., USA

In this paper, the authors address the question, ?In the brave new world 
of Web services and service-oriented architectures (SOA), how does data 
fit in??  They bring data modeling concepts to bear on the world of 
services, yielding an approach in which enterprise data access is handled 
by a collection of interrelated data services. It is then shown how the 
approach can be realized on a foundation of XML standards, namely XML 
Schema, Web services, and XQuery. The authors show that this approach 
provides a uniform and declarative framework for integrating enterprise 
data assets that are drawn from disparate underlying sources, including 
both queryable and non-queryable data sources as well as data that is 
encapsulated by Web services. How the approach yields data services that 
are easily and efficiently reusable is also explained.

CALL FOR PAPERS

Mission of JWSR:

Web Services are among the most important emerging technologies in the 
e-business, computer software and communication industries. The Web 
Services technologies will redefine the way that companies do business and 
exchange information in the twenty-first century. They will enhance 
business efficiency by enabling dynamic provisioning of resources from a 
pool of distributed resources. Due to the importance of the field, there 
is a significant amount of ongoing research in the areas. In a parallel 
effort, standardization organizations are actively developing standards 
for Web Services. The Web Services are creating what will become one of 
the most significant industries of the new century. The International 
Journal of Web Services Research is designed to be a valuable resource 
providing leading technologies, development, ideas, and trends to an 
international readership of researchers and engineers in the field of Web 
Services.
