you should describe your question a little bit more specific please.
But here is a general answer to your question:
Each YAWL specification is composed of one or more YAWL nets: exactly one starting net (also known as the root or parent or top-level net) and zero or more sub-nets. A net has two mandatory elements: an input condition which acts as the starting point (graphically represented with a Play-Button) and an output condition which signals the end (quadrangle).
The net is a based on petri nets.
I know this anwser is very general, but I hope i could help you and and if you have any questions.
