Re: [Pharo-users] NewWave - WorkflowEngine

by Sebastijan Kaplar

Hello as Norbert I'm also interested. To provide a little more context I'm working on a NewWave as a part of my PhD. The new and interesting side that is supported is that the NewWave integrates with TaskIT for tasks executions, with now added support for boundary events and task scheduling. I haven't used Workflow from NetStyle, but as I can tell from the GitHub only part of the engine remains, without any examples or user interfaces, and it didn't support mentioned? Is there any chance that the original netstyle workflow is to be found and checked out?

Re: [Pharo-users] Why are package tags not proper sub-packages?

by Tim Mackinnon

I chatted with guys about this - and it turns out that I was thinking of packages as if they were projects, however in reality we are waiting for a proper âprojectâ model (this is what Cargo - whoâs new name Iâve forgotten - is all about). So I should promote my use of tags up to proper packages and for now âprefixâ my packages with a project name. This might explain why when you create a unit test , it creates an automatic top level package (and not a tag), which has often confused me in the past. Iâm still a bit unsure what tags would then be used for in a world with projects. But it seems that the guidance is to think projects / packages (not baseline/package/tags) Tim Sent from my iPhone > On 20 Apr 2019, at 00:15, Tim Mackinnon <tim(a)testit.works> wrote: > > Well I guess most usages are âload 3rd party baselineâ and you donât really care who owns the extension methods (all the sub-tags are normally part of the parent project anyway). > > If you do add any extensions to that project, you probably also donât notice they donât show up in any tags of the classes you extend (only in the containing project).

Re: [Pharo-users] A4BP and BpmFlow

Norbert, > yes, Iâm interested, too, in how we can get a workflow engine and a simple reification of a workflow model that can be used in a lot of scenarios. Can list some scenarios to tell you if BpmFlow can do it ? BpmFlow can be integrated to regular Business Applications to add workflow capabilities to regular Applications. I'm working on one of this type of application right now (the documentation is being developed now so you will find some holes on it- after i finish the application i will finish the documentation). Check: https://bpmflow.gitbook.io/project/engineering-models/architecture-for-atop… > That is something Iâm working on. In the IoT space this will become very important. We will have devices attached to a network that need to work together in a workflow scenario to solve a problem. We have the prerequisites for this, bringing devices into a network and manage them centrally. In the mid-term I want to use a workflow engine that can be adjusted to these needs. In this case i think that devices will send information using services and the Workflow (on the server) will centralize that operation. I do not see any problem here but the definition of the Workflow itself. For example opening a Bank account from the mobile. This workflow will have to connect to different third parties applications through services. regards bruno

> I also thing we need to do it Â« a la smalltalk Â» and consider workflow split over multiples images. Does A4BP or BPM flow manage that ? What exactly do you want to split over multiple images ? It can be only applied to parallel tasks. 1) The execution of the workflow ? Task1 executed by VM1, Task2 executed by VM2 and so on ... 2) Task Assignment for different users ?Â Suppose there are 4 parallel task to be done in a workflow these task are split to different VMs. 3) Add here any other options to split over multiple VMs. BpmFlow does not support 1) for ScriptTasks, i think for this you will need a master VM to orchestrate the execution. Definitely 2) is supported, on the same BPM Process different user tasks can be executed by different VMs (remember Bpm Flow run on GemStone, it should be ported to Pharo first). I talking about a Frontoffice application here (different from case 1) where at the same time different users can take an available task (of the same BPM Process) to finish and eventually these tasks can be served by a different VMs. Actually 1) can be implemented in BpmFlow without a master VM. Let suppose that a one point N Script Tasks (long and complex scripts) are generated in the same BPM Process. Those Script Tasks can be put on a RcCollection (or a table if you use a RDB) and multiple VMs can access that collection and execute tasks. I just added this an issue: https://github.com/brunobuzzi/BpmFlow/issues/845 Bpm Flow does something like this for Timer Events (events collection can be accessed by multiple VMs): https://bpmflow.gitbook.io/project/functional-and-technical-information/tim… Regards, Bruno

I fix the README file. A4BP is a BPMN engine built originally by Alvaro Jose Peralta. With A4BP, you can download a BPMN file, do a simulation with BPMSim and assess various aspects (static, dynamic) of a business process. There is some limited support for Process Mining also. We use Roassal to assess visually processes. We made a publication where we use A4BP to assess rescue processes after a disaster in 2015: https://link.springer.com/chapter/10.1007/978-3-319-24399-3_14 http://bergel.eu/MyPapers/Alva15-ISCRAM.pdf Regards, -- Serge Stinckwic h Int.
