Leading Technology Vendors Announce Publication of 'BPEL4People'

Extends WS-BPEL 2.0 OASIS Standard, submission to OASIS imminent

A group of technology vendors, including Active Endpoints, Adobe, BEA Systems, IBM, Oracle and SAP AG, have announced the publication of “BPEL4People” specifications, which define an approach for integrating human interactions using Web Services Business Process Execution Language (WS-BPEL) 2.0.

BPEL4People extends the capabilities of WS-BPEL to support a broad range of human interaction patterns, allowing for expanded modeling of business processes within the WS-BPEL language.

WS-BPEL focuses on business processes that orchestrate Web service interactions. However, in general, business processes are comprised of a broad spectrum of activities that most often require the participation of people to perform tasks, review or approve steps and enter data – for example, a credit approval scenario that may require approval on certain transaction limits or activity levels. These human interactions are now addressed in the new specifications.

BPEL4People is comprised of two specifications including:

  • WS-BPEL Extension for People which layers features on top of WS-BPEL to describe human tasks as activities that may be incorporated as first-class components in WS-BPEL process definitions
  • Web Services Human Task introduces the definition of stand-alone human tasks, including the properties, behavior and operations used to manipulate them.  Capabilities provided by Web Services Human Task may be utilized by Web services-based applications beyond WS-BPEL processes.

The authors plan to submit the specifications to OASIS in the near future and will propose a Technical Committee to produce an OASIS standard based on it. OASIS (Organization for the Advancement of Structured Information Standards) is a not-for-profit, international consortium that drives the development, convergence and adoption of e-business standards.

Trackback Added: BPEL4People: Right idea, wrong execution; Last week, BPEL4People was formally moved to OASIS. BPEL4People is the right idea, but the wrong execution. There must be a way to integrate people into business processes, but the specification presented to fulfill this goal is far too complicated.
