View Full Version : Software for executing Workflows

August 20th, 2009, 05:17 PM
I am thinking of implementing a (simple) workflow software.
I better consult you guyz to know what already exists in the jungle.

The concept is simple :
I draw a flow chart (graph with nodes and directed edges).
For each node I can specify a command to run. The output of the node command will be piped to the input of following nodes.

Google did not help me much in finding this.

I found phatch which somehow does this for images, but I would like something generic and that is not limited to linear flow (i.e. nodes can be run in parallel, execution of following node starts when all inputs ready)

Technically, I would imagine something very simple :
- a canvas widget for nodes and edges
- a tab widget with command field and parameters
Cherry-on-top :
- a script API to bring to GUI some infos like input,output and parameters help, logging,etc.

I was thinking of something smaller... a light GUI without Application server etc.

I'll make a prototype using something like this (Qt4 scenes) :

I made a workflow editor and runner, using Python, with a Qt4 GUI.
