How-to delete all users in the YAWL engine?
When you are logged in as admin in the YAWL control center, you can import and export organisational data via a simple click of a button in section Org Data. But what if you want to start from a clean slate and delete all organisational data? Deleting roles and users one by one via the YAWL control center can become tedious. There is a very simple workaround for that: in the engine/databases directory of the standard YAWL4Study installation there is a directory called yawldb. Replace this directory with the one from misc/yawldb and the engine's organisational data are reset. NOTE: this also deletes all loaded workflow specifications and cases.
