OASIS Members Propose Charter for WS-BPEL Extension for People

OASIS announced that consortium members have submitted a charter proposal
for a new WS-BPEL Extension for People (BPEL4People) Technical Committee.
Companies sponsoring the proposal include Active Endpoints, Adobe, BEA,
IBM, Oracle, SAP, Software AG, and Sun Microsystems. The designated TC
Convenor is Jeff Mischkinsky (Oracle). This technical Committee proposal
follows a June 2007 statement from a group of six technology vendors,
including Active Endpoints, Adobe, BEA Systems, IBM, Oracle, and SAP AG,
announcing that the two-part BPEL4People specification would be submitted
to OASIS in the near future. The Web Services Business Process Execution
Language Version 2.0 (WS-BPEL) specification was published as an approved
OASIS Standard in April 2007. It provides a language for the
specification of executable and abstract business processes, extending
the Web Services interaction model to support business transactions.
However, "BPEL was not designed for human workflow." The proposed
BPEL4People Technical Committee would define: (1) extensions to the
OASIS WS-BPEL 2.0 Standard to enable human interactions, and (2) a model
of human interactions that are service-enabled. This work will be carried
out through continued refinement of the Version 1.0 documents released
in June 2007, consistent with the "WS-BPEL Extension for People --
BPEL4People" Joint White Paper published by IBM and SAP in July 2005.
In particular, the new TC work will focus upon: (1) defining the
specification of a WS-BPEL extension enabling the definition of human
interactions ("human tasks") as part of a WS-BPEL process; (2) defining
the specification of a model enabling the definition of human tasks
that are exposed as Web services; (3) defining a programming interface
enabling human task client applications to work with human tasks.
