confusion of WS-BPEL
The following presentation
http://www.ebpml.org/Meta,%20Meta,%20Meta.ppt
describes the confusion of WS-BPEL
Quoted from slide 17
•Business component can exhibit a long running behavior and looking from the perspective of such component, the flow of messages between itself and other components can also be expressed using a meta language.
–This is orchestration
•The confusion is that Components are typically very coarse and can directly be exposed to partners. The long-running behavior might also be complete.
As I know, WS-BPEL process itself can be described by WSDL.
Clients can access this WS-BPEL process as WSDL service. Then this
WS-BPEL process should be treated as a complete component and
be directly exposed to clients.
This leads to WS-CDL which namely is Choreography Description
Language.
