[bpel-dev] BPEL and Semantic Web Services

["Ralf Weinand" <weinanr@xxxxxxxxxxxxxxx>]

Hello,

I´m writing a thesis about BPEL and Semantic Web Services,
which involves the development of a BPEL editor that can handle
Semantic Web Services
and takes advantage of the semantic annotations of input and output parameters
to support the user in defining the data flow.

I was thinking of building this on top of the existing BPEL project.
I am quite new to EMF-based projects (I completed the EMF-tutorials though :-))
and would like to know if you can tell me if it is reasonable to use
the BPEL-project
for my purpose, and where to start.

In the end the user should be able to
1. load Semantic Web Services (OWL-S files)
2. drag&drop service operations of Semantic Web Services into the editor
3. semi-automatically generated data flow constructs for each Semantic
Web Service,
    which involves some reasoning in the background and results in the
generation of a
    sequence of activities:
    1. Assign (which will do a xslt transformation from OWL to XSD)
    2. Invoke (to call the underlying WSDL Web service)
    3. Assign (to convert the result back to OWL)
4. export the process and all generated resources (like XSLT-files)
into an execution system (like ActiveBPEL engine)

Any comments very much appreciated! :-)

Thanks,

Ralf
