Paper: Facilitating rich data manipulation in BPEL using E4X
Hi ODEers,
I'm happy to share our paper about "rich data manipulation in BPEL" with
you. It describes the first publicly available ODE extension activity
and extension assign operation and incorporates the power of
JavaScript/E4X into BPEL. It is still in alpha/beta but will be shipped
as an example for ODE's extension points with ODE 2.0. Furthermore I'm
sure that it can significantly ease the process developer's day job.
Comments are of course more than welcome :)

Facilitating rich data manipulation in BPEL using E4X
(Tammo van Lessen, Jörg Nitzsche, Dimka Karastoyanova)

Abstract:
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.
Although BPEL's built-in functionality is sufficient for simple data
manipulation tasks, it becomes very cumbersome when dealing with more
sophisticated data models, such as arrays. ECMAScript for XML (E4X)
extends JavaScript with support for XML-based data manipulation by
introducing new XPath-like language features. In this paper we show how
E4X can help to significantly ease data manipulation tasks and propose a
BPEL extension that allows employing JavaScript/E4X for implementing
them. As E4X allows defining custom functions in terms of scripts,
reusability with respect to data manipulation is improved. To verify the
conceptual framework we present a proof-of-concept implementation based
on Apache ODE.
