What Happens in Practice
How did
Dollar Auto Rentals do it?
This is a famous Microsoft .NET success story.
Companies establish ad hoc conventions
There's a cancelation operation
No authorization is required or done ad hoc
Payment is done outside of WSDL
It is pre-arranged what the operations and
messages mean
But this does not scale
for dynamic discovery
of public services
because it requires advance knowledge and agreement
for each different service.
Remember the
trick question?
