Are there any resources regarding petri nets or control flowâ¦/workflow patterns in pharo or smalltalk? thanks, Norbert

We have done some work with one student of Alexandre about BPMN: http://a4bp.com/ and there is PNTalk also: https://github.com/SergeStinckwich/PNTalk Long time ago I was able to do process mining from logs and generate Petri Nets: https://www.youtube.com/watch?v=wdf80t32v-0 Regards, -- Serge Stinckwich UCN & UMI UMMISCO 209 (IRD/UPMC) Every DSL ends up being Smalltalk http://www.doesnotunderstand.org/

I downloaded the app but it opens with a black screen on my Mac laptop.

Thanks, that is what I was looking for.

That is really close to what I want to play with. Did you ever encounter van der Aalst workflow pattern in that context. Do you know any material comparing the approaches? thank you very much, Norbert
Norbert 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 Stef On Wed, May 10, 2017 at 6:13 PM, Norbert Hartl <norbert@hartl.name> wrote:

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 Bröger 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. Norbert

Is the source code available somewhere? Norbert
yes :) I contacted the guy to ask for the smalltalk code but he never replied to me may be someone else should try. stef On Thu, May 11, 2017 at 9:59 AM, Serge Stinckwich < serge.stinckwich@gmail.com> wrote:

I ask him but he don't have the code anymore, maybe this is possible to do a retroengineering from the PhD thesis ? Envoyé de mon iPhone

There is code in several papers, including this one: https://www.dropbox.com/s/lc2ev4841lzn9q0/Worfklow-Continuations.pdf?dl=0 Phil On Thu, May 11, 2017 at 9:07 PM, <serge.stinckwich@gmail.com> wrote:

I read that paper too and I was wondering about the trempoline piece he uses. Is there someone having implemented that using Pharo? His code was VW. Phil On Thu, May 11, 2017 at 8:54 PM, Stephane Ducasse <stepharo.self@gmail.com> wrote:

Yes this is the usual story .... software rots at the end. I guess you are using last version of mac os x and the VM provided on the web site does not work anymore. Give me 3 students and I will change this situation ;-) I want to continue this work but I have to find motivated students.

I know van der Aalst work but I don't know exactly what do you mean by workflow pattern.

Ah, right. I just need to use my own vm to start it. I'll try again :) Norbert
