Boston, MA, USA; 12 April 2007 — OASIS, the international standards consortium, today announced that its members have approved the Web Services Business Process Execution Language (WS-BPEL) version 2.0 as an OASIS Standard, a status that signifies the highest level of ratification. WS-BPEL uses Web services standards to describe business process activities as Web services, defining how they can be composed to accomplish specific tasks.
"The concept of BPEL that began in the earliest days of Web services has become a cornerstone, not only for bringing more finely grained business processes closer to the business department, but also for ensuring that common ways can be constructed among technology providers designing frameworks for future Service Oriented Business Processes," said Charles Abrams, Research Director at Gartner. "The approval of WS-BPEL as an OASIS Standard should be noted as a milestone in the fulfillment of the open Web services vision."
WS-BPEL defines a model and a grammar for describing the behavior of a business process based on interactions between the process and its partners. The interaction with each partner occurs through Web services interfaces. The WS-BPEL process defines how multiple service interactions with these partners are coordinated to achieve a business goal, as well as the state and the logic necessary for this coordination.
"Think of a WS-BPEL process as a reusable definition that can be deployed in different ways and in different scenarios, while maintaining a uniform application-level behavior across all of them," said Diane Jordan of IBM, co-chair of the OASIS WSBPEL Technical Committee. "WS-BPEL introduces systematic mechanisms for dealing with business exceptions. This is essential because not all transactions are straightforward and simple. WS-BPEL lets you define how you want activities to be compensated in cases where exceptions occur or a partner requests reversal."
WS-BPEL separates the public aspects of business process behavior from internal or private aspects–and supports both. The standard can be used both for executable processes, which describe the actual behavior of participants in business interactions, and for abstract processes, that may be used to represent publicly observable behaviors. Abstract processes serve a descriptive role and allow for more than one possible use case.
"By providing a language for specifying both executable and abstract business processes, BPEL extends the Web services interaction model to help better support business-to-business transactions," explained John Evdemon of Microsoft, co-chair of the OASIS WSBPEL Technical Committee. "This protects business partners from the need to reveal all their internal decision making and data management to one another. Separating public from private processes also provides companies with the freedom to change confidential aspects of the process implementation without affecting the observable behavior."
WS-BPEL leverages other Web services standards such as SOAP and WSDL for communication and interface description. By describing the inbound and outbound process interfaces in WSDL, BPEL enables them to be easily integrated into other processes or applications. In turn, this allows consumers of a process to inspect and invoke a BPEL process just like any other Web service, thereby inheriting all other aspects of a Web service such as quality of service policies.
OASIS president and CEO, Patrick Gannon, observed, "WS-BPEL is a fine example of the benefits that can be gained by open standardization and widespread collaboration. The BPEL specification evolved considerably under the OASIS process and emerged stronger–a true, foundational standard for Web services and SOA."
More than 37 organizations collaborated to develop WS-BPEL, including representatives of Active Endpoints, Adobe Systems, BEA Systems, Booz Allen Hamilton, EDS, HP, Hitachi, IBM, IONA, Microsoft, NEC, Nortel, Oracle, Red Hat, Rogue Wave, SAP, Sun Microsystems, TIBCO, webMethods, and other members of OASIS. Active Endpoints, IBM, Intalio, SEEBURGER, and Sun Microsystems verified successful usage of WS-BPEL, in accordance with eligibility requirements for all OASIS Standards. Several open source implementations of WS-BPEL 2.0 are currently available or in development.
The WS-BPEL OASIS Standard and the archives of the OASIS WSBPEL Technical Committee are publicly accessible. OASIS hosts the ws-bpel-dev mailing list for exchanging information on implementing the standard.
Support for WS-BPEL OASIS Standards
Active Endpoints "The approval of WS-BPEL 2.0 marks a significant milestone in the evolution of service-oriented computing. In much the same way that SQL provides a standard data language for relational databases, BPEL provides a standard language for service orchestration. Active Endpoints has been an enthusiastic contributor to the development of WS-BPEL 2.0, and we look forward to participating in future endeavors related to this critical standard," said Chris Keller, co-founder and vice president of Product Development, Active Endpoints, Inc.
Adobe "BPEL is already the industry foundation for orchestrating Web services. The new WS-BPEL v2.0 standard is an important milestone that represents a significant evolution of the original specification. WS-BPEL enables our customers to build and deploy successful Web services and SOA projects that scale with the organization as they add new partners, customers and services to their infrastructure. We were pleased to work alongside other technology vendors to develop WS-BPEL v2.0, and look forward to helping to accelerate its adoption," said Charlton Barreto, Senior Computer Scientist and Architect at Adobe.
BEA Systems "BEA sees WS-BPEL 2.0 as a very important milestone in the ongoing effort to align the industry behind a common technology for orchestrating services within an SOA," said Michael Rowley, BEA Technical director and standards architect, in a statement released by the company. "This supports our efforts to serve our customers through aggressive support of open standards."
HP "As enterprises work to speed adoption of SOA, they need standards to ensure business process interoperability, especially in multiple vendor environments. HP SOA Systinet, a system-of-record for SOA business services, supports the latest WS-BPEL standard through the Governance Interoperability Framework (GIF), a widely-accepted method for integrating SOA-enabling technologies. This will help our customers optimize the business outcomes of their SOA initiatives by capturing business process related information," said Avrami Tzur Vice President of SOA Software, HP.
IBM "IBM’s leadership in SOA has been built upon a foundation of standards and service oriented principles. IBM delivers Business Process Management (BPM) enabled by SOA. Core to the execution of our process portfolio is Business Process Execution Language (BPEL). We recognized the benefits and importance of the BPEL specification at its outset and that’s why we have built our process technology based on it. We are thrilled that OASIS has ratified the specification as a formal standard, as this lays the foundation and a clear path for increasing portability of processes, protecting customer investments, reducing risk, and providing stability and a clear direction for the future of process execution semantics," said Sandy Carter, Vice President, SOA & WebSphere Strategy, Channels and Marketing, IBM.
