The concrete experiences at Audi with importing BPA models in BPEL
BPEL: Definition

BPEL is an XML-based language for
standardizing business processes in a
distributed or grid computing environment
that enables separate businesses to
interconnect their applications and share
data.

BPEL: Versions and History

Descends from IBMs WSFL and Microsofts XLANG,
combination called BPEL4WS

BPEL4WS appeared in 1.0 and 1.0 – without being
standardized yet

WS-BPEL 2.0 Spec by OASIS in September 2004

BPEL 2.0 standardized in April 2007

In June 2007 BPEL4People published by
Active Endpoints, Adobe, BEA, IBM, Oracle and SAP

Distinction BPEL & XPDL

XPDL = XML Process Definition Language
WfMC = Workflow Management Coalition

XPDL 1.0 ratified by WfMC in 2002

XPDL defines a XML schema for specifying the
declarative part of workflow

It‘s focus is less in Process execution but in Process
interchange between differnet products (Modelling
tools, Workflow engines etc.)

xmlns

XML namespaces define uniquely named elements and
attributes in an XML instance

XML namespace does not require that its vocabulary be
defined, though it is fairly common practice to place either a
Document Type Definition (DTD) or an XML Schema

xmlns:bpws=http://schemas.xmlsoap.org/ws/2004/03/business-process/

The concrete experiences at Audi with importing BPA models in BPEL
Elements of BPEL
Basic and Stuctured Activities

BPEL activities perform the process logic

activities are divided into 2 classes: basic and structured

basic activities describe elemental steps of the process
behavior

structured activities encode control-flow logic


<invoke> – calls Web Services
<invoke name="checkSolvency" partnerLink="bank"
portType="check" operation="checkSolvency"
inputVariable="customer" outputVariable="sol"/>

<receive> - waits for message

<reply> - replies to a message

Elements of BPEL
PartnerLinks

<partnerLink> - describes comunication partners

the process is one of the partners, and another service is
the other partner

partnerLink defines the role that the process plays and
the role that the partner service plays in the particular
exchange

Elements of BPEL
Scopes

<scope> - provides the context which influences the
execution behavior of its enclosed activities

this behavioral context includes activities like: variables
or partner links

contexts provided by <scope> activities can be nested
hierarchically

a part of the state of a business process

visible only in the scope in which it is defined
<variables>
<variable name=“a”/>




ARIS uses ePC notation
impossible to generate BPEL Code
directly in ARIS
vendor specific solutions avaible
e.g. Oracle BPA Suite, ARIS BPEL

IDS Scheer statement*
 “ePC is for functional process modelling
only
 BPMN if process are to be implemented
or automated“

Today‘s situation

no 100% match between BPEL 2.X and BPMN
2.0 and vice versa (e.g. because of deficits of
human interactions)

a generic BPEL-export is hardly possible


On the horizon

OMG responsible for standardization of BPEL
as well as of BPMN
BPEL 3.0 expected to be released Q3/2008

better match between BPMN 2.0 and BPEL 3.0

easier BPEL export/imports with less reworking
