Business Process Execution Language (BPEL) is
an XML-based Web service composition language
that is commonly used for the orchestration of
business processes. Orchestration refers to the
sequencing of services, usually defined in a separate
Web Services Definition Language (WSDL)
document, in order to provide additional logic to
process data, which essentially creates the
application logic. In certain situations, when
business goals or policies change, these services
(external to the orchestrated process) may change in
a way that it affects the orchestrated process. For
example, some services may be removed and new
ones introduced. In situations like this, BPEL models
need to be changed accordingly. In large and
complex business processes, due to the verbose
nature of BPEL, making alterations to BPEL
descriptions is an arduous task, and can often lead to
inconsistencies and errors. This paper demonstrates
a way to map BPEL processes and related WSDL
service descriptions into algebraic expressions,
which encapsulate all process elements into a single
phrase. The purpose of these algebraic expressions is
to easily identify the effect of service changes in the
orchestrated process, which in turn enables the
required changes to be carried out efficiently in-situ
within a given context, without disturbing the
consistency of the overall BPEL document. The
proposed algebraic methodology is based on Kleene
Algebra with Tests (KAT), which is a new branch of
algebra that lends itself for practical modeling
purposes.
