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.
