Well a url is really dictated by your underlying resource model that you
want to expose.
In my case I have a service: /wfcs (workflow chaining service)
I have workflow resources
-> /wfcs/workflows/{id}
Workflows can have many process definitions
-> /wfcs/workflows/{id}/definitions/{id}
When I launch a workflow, I really create an instance resource so I can
track it.
-> /wfcs/workflows/{id}/instances/{id}
A running instance of a workflow has many traces (in/out of activities)
I can get an atom feed of those traces by adding a .atom or .rss extension:
-> /wfcs/instances/{id}/traces.atom
I can get a workflow atom/rss feed in a similar manner
-> /wfcs/workflows.atom
So on and so forth.
There is also an APP service document that describes the collections at :
-> /wfcs/app
This is inline with the Atom Publishing Protocol (APP).
You may also want to have a WADL document to describe your application:
-> /wfcs.wadl
Does this make sense?
