I know petri nets and I was wondering if you were interested in worklow (as in microworkflow).
because I think that a simple extensible workflow library is missing in Pharo
I'm interested in workflow but came to petri nets as they are similar. But I don't know what is the real difference between those two. I've read a bit about van der Aalst workflow patterns and a revision of Br��ger for them. But I know too little of the topic.
We have more projects where we choose a state machine in order to properly manage state changes in our applications. In some projects the transitions are simple and clear so that they can be described generically. And that brings me to workflow and petri nets. A more generic approach will lower the amount of code to be written and opens a way to serialize the flow, have a DSL for it or use it together with Roassal.
