PRESS RELEASE

Pi4 Technologies announces WS-CDL to WSDL and BPEL generation.

6th July 2005

Pi4 Technologies (www.pi4tech.com), a UK based open source company is 
pleased to announce the release of the second version of its WS-CDL 
(Web Services Choreography Description Language) tools suite.

The tool suite is provided as an open source (Apache 2.0) plug-in to 
Eclipse 3.X and is available through the open source Pi4SOA website at 
www.pi4soa.org and an examples repository is available from the Pi4 
Technologies web site at www.pi4tech.com.

The tool suite includes a validating editor for constructing valid 
WS-CDL which conforms to the current latest draft of the WS-CDL 
specification along with an editor for creating test scenarios that can 
be used to test, simulate and even show conformance of a set of 
messages to a WS-CDL description. Also provided in the core release is 
the ability to generate WSDL1.1 and WSDL2.0 directly from a WS-CDL 
description.

An experimental release for BPEL4WS1.1 is provided separately. This 
experimental version of BPEL generation demonstrates how WS-CDL can be 
used at a higher level and how BPEL can be used as an end-point 
language for service realisation. The experimental release has been 
tested with ActiveBPEL (www.activebpel.org). An example can be 
downloaded from the pi4tech website while all of the tools can be 
downloaded from the pi4soa open source website.

Pi4 Technologies encourages the community to try our WS-CDL and provide 
feedback.

Steve Ross-Talbot, CEO and co-founder of Pi4 Technologies, said "We are 
very pleased to provide an updated version for WSDL generation and an 
experimental addition for BPEL generation. The marriage of WS-CDL and 
BPEL fulfills the vision espoused by the Web Services Choreography 
Working Group in meeting the demands of many customers. In this version 
the experimental BPEL generation allows users to specify the peer to 
peer behavior of services and then render it directly into BPEL without 
the need to code in BPEL. The single step approach of using WS-CDL to 
describe and then BPEL to execute offers the possibility of creating 
large scale distributed systems in a safe more robust and interoperable 
manner and it removes the need to have a single controlling service 
that results in a lower operational risk without loss of control.".
