The initial work of the Coalition focused
on publishing the Reference Model and Glossary, defining a common
architecture and terminology for the industry. A major milestone
was achieved with the publication of the first versions of the
Workflow API (WAPI) specification, covering the Workflow Client
Application Interface, and the Workflow Interoperability specification.
The Audit Data specification was added in 1997, being followed
by the Process Definition Import/Export specification.
A further version of WAPI covers Application
Invocation API·s, completing the Coalition·s initial deliverables
across the five interface functions. Further work includes the
completion of a common object model with object bindings for IDL
and OLE, interoperability extensions for security, and additional
interoperability models.
The Coalition has validated the use of
its specifications through international demonstrations and prototype
implementations. In direct response to growing user demand, live
demonstrations of a workflow interoperability scenario have shown
how business can successfully exchange and process work across
multiple workflow products using the Coalition·s specifications.
