The Business Process Execution Language (BPEL) uses XML to specify
the data used within a process and realizes data flow via (globally)
shared variables. Additionally, assign activities can be used to
copy (parts of) variables to other variables using techniques like
XPath or XSLT. BPEL for Semantic Web Services (BPEL4SWS) employs
SAWSDL to give meaning to data by referring to ontological concepts
and to enable a seamless mapping of XML data and its ontological
representation. In this paper we show how this ontological knowledge
can be used to ease the definition of data flow in BPEL.We therefore
extend BPEL and introduce the concept of mediaton as a first class
citizen. We give an example of data mediation in BPEL processes and
show how process modellers can benefit from the ontological
knowledge when specifying data manipulation declaratively instead of
having to implement data manipulation each time a process is
modelled.
