Analysis of WS-BPEL Processes in PRISM

2011 Fifth International Conference on Theoretical Aspects of Software Engineering, 2011
WS-BPEL has emerged as the de facto industry standard for composing Web services. With the wide attention for WS-BPEL, Quality of Service (QoS) for it has become a key differentiator to judge the services with same functionalities. One main challenge currently is how to analyze the QoS of WS-BPEL services at the early design phase.

An architecture for providing context in WS-BPEL processes

Proceedings of the 2008 conference of the center for advanced studies on collaborative research meeting of minds - CASCON '08, 2008
Web Service Business Process Execution Language (WS-BPEL) business processes are increasingly used by organizations to automate their business activities. As the pace of change in an organization increases, these processes will be required to be more flexible; to do so they will have to account for an increasing amount of changing environment state, or

A standard-driven implementaion of WS-BPEL 2.0

Proceedings of the 2010 ACM Symposium on Applied Computing, 2010
We present a systematic study of the WS-BPEL 2.0 standard based on two complementary methods: the process of constructing a new high-level WS-BPEL implementation driven by the structure of the standard, and an empirical evaluation of existing interpretations of the standard reflected in five widely available WS-BPEL-implementations, both commercial and

BPEL4RBAC: An Authorisation Specification for WS-BPEL

2008
Business process management is designed to make business activities and trade easier and more cost effective. The increasing business integration and legal requirements raise the need for secure business processes. However, the openness and distribution nature of inter-organisational business processes may result in more security breaches.

Formal Modeling of Transaction Behavior in WS-BPEL

2008 International Conference on Computer Science and Software Engineering, 2008
Web Services can be composed to build domain-specific application and solution. Some Web Services Composition (WSC) standards are proposed, for instance, WS-BPEL and WS-CDL. WS-BPEL consists of basic activity, structured activity and control-flow. It uses control-flow to construct sequence, branching, parallelism, synchronization, etc.

A User Interface for Personalising WS-BPEL Scenarios

2021
Due to the huge volume of web services available, both locally and in the cloud, the performance of users and systems need significant research attention. Since WS-BPEL is the dominant language for orchestrating individual web services into business processes, by composing WS-BPEL scripts/scenarios, graphical notations facilitating WS-BPEL design can ...

WS-BPEL Business Process Abstraction and Concretisation

2009
Business process management is tightly coupled with serviceoriented architecture, as business processes orchestrate services for business collaboration at logical level. Given the complexity of business processes and the variety of users, it is a sought-after feature to show a business process with different views, so as to cater for the diverse ...

Access Control and Authorization Constraints for WS-BPEL

2006 IEEE International Conference on Web Services (ICWS'06), 2006
Computerized workflow systems have attracted considerable research interest in the last fifteen years. More recently, there have been several XML-based languages proposed for specifying and orchestrating business processes, culminating in WS-BPEL. A significant omission from WSBPEL is the ability to specify authorization information associating users ...

Migration Validity of WS-BPEL Instances Revisited

2013 IEEE 16th International Conference on Computational Science and Engineering, 2013
WS-BPEL processes ought to be adaptable even at run-time so as to adapt to the changing environments and requirements. It is cost-ineffective and time-consuming to restart a running WS-BPEL instance from scratch after the WS-BPEL process is changed. Instead, a WS-BPEL instance had better be transferred to the updated process.

Towards a Reusable Fault Handling in WS-BPEL

International Journal of Software Engineering and Knowledge Engineering, 2014
Service Oriented Architecture (SOA) is an evolution of distributed computing and it is based on the concepts of interoperable services. To enable reliable and robust service oriented information systems, it is important to establish an effective fault handling.
