Workflow management and application generation tool for Plone.

Project description


Our vision for uwosh.northstar is as a complete through-the-web (TTW) tool for generating workflow applications, ie. a custom content type combined with an assigned custom workflow.

Right now it adds a control panel entry Workflow Manager where you can access the workflow tool. It also adds a Workflow App Generator control panel entry where you can generate your workflow app products.

Creating content types is easily done by using Dexterity. The tool will simply dump your dexterity content type. If you can not use dexterity, the tool also supports using PloneFormGen as your modeling tool in which it’ll create a corresponding Archetype for the PloneFormGen form you’ve created.

uwosh.northstar is strictly for add-on product workflows and content types. By design, the tool cannot be used to edit default Plone workflows.

It provides all the functionality you need to manipulate workflows easily through the web, using an AJAX-powered interface and to generate the products of the content types and workflows you’ve created TTW.

You can take a look at the new video demonstrating the workflow editor

Tested with

  • Firefox

  • Google Chrome

  • Safari

  • Opera

  • IE8


Just add uwosh.northstar to your buildout eggs sections and then install the “North * “ product in the add/remove products control panel.

In older versions of Plone, you might need to add to your zcml slug section of your buildout also.

Workflow App Generation with PloneFormGen

>>> eggs =
>>>   ...
>>>   Products.PloneFormGen
>>>   ZopeSkel
>>>   Paste

Workflow App Generation with Dexterity

>>> eggs =
>>>   ...
>>>   ZopeSkel
>>>   zopeskel.dexterity
>>>   Paste


One feature of North * is that it can create a Diagram of the workflows you create TTW.

The inspiration for this piece was pretty much taken from DCWorkflowGraph.

In order to enable this feature, you’ll need to install the Graphviz library. Information can be found at

Produced by Secret Laboratory Number 1 at UW Oshkosh.
