Abstract

Web service orchestration represents an open
and standards-based approach for connecting web services
together leading to higher level of business processes.
Business Process Execution Language (BPEL) engines are
designed to handle this orchestration. However, web service
compositions into BPEL suffer from several non-functional
requirements such as security. To address this problem, we
propose in this paper a novel approach that is based on a
harmony between the licensing concept offered by eXtensible rights Markup Language (XrML), aspect-oriented programming (AOP), and web service compositions in BPEL.
Our proposed approach, based on XrML, offers the ability
to associate security licenses with activities offered by the
composite web services. It allows to automatically generate
BPEL aspects depending on the developed licenses, to separate between crosscutting concerns of the composed web
services, and provides an easy way to include and update
the non-functional requirements (e.g., security) into a BPEL
process. It offers also the ability to validate the licenses,
at runtime and without affecting the business logic of this
model. To evaluate our approach, we have developed an

inventory control system (ICS) sample that is composed of
several web services. Case study and performance analysis
are presented to demonstrate its feasibility as well.
