Overture covering several VDM dialects instead of just OML?

Overture will undergo a series of changes to make it more linkable with the VDM “brand”. Dropping the OML name is one of the actions and avoiding the reference to different dialects might help with citations. Referring to it as VDM tools: Next Generation could also improve the visibility of Overture.

Overture will support different VDM dialects. LB is to decide which changes to the dialect will be supported but anybody is allowed to make any their own experiments/changes. Rodin Report - Kenneth & Miguel
