Diaflux is a graphical workflow authoring plugin for KnowWE.\\
It is used to model complex problems in an easy to read and understandable fashion.\\


!! Syntax and Semantic\\

An Diaflux workflow is defined inside the markup __DiaFlux__\\

!! Diaflux Editor

The Diaflux workflow may be edited using the __Visual Editor__.

! Diaflux elements

* __Start node__: entry point for a DiaFlux\\
* __Exit node__: exit point of a DiaFlux\\
* __Action node__: select a question, solution, or other flowchart and model an interaction with this it.\\
* __Comment node__: use this node to provide annotations to transitions or nodes.\\
* __SnapShot node__: used to inhibit the truth maintainance to reverse decisions before this snapshot. (Behaves like a diode.)\\


!Editor tools\\

* __Save flowchart and close editor__\\
* __Revert changes__\\
* __Close editor__ (without saving)\\
* __Delete flowchart__\\


!! Best Practices\\

* A DiaFlux flowchart shall have a unique name.\\
* One flowchart needs to be checked for Autostart. (That is where a session workflow will start.)\\
* Do not overload a single flowchart. Model rather small parts and reference them in a parent flowchart.\\
  Rule of thumb: Not more than a monitors field of view.\\
