Overture Community Process

Note: Language Board = Executive Committee.

LB to be downsized to 5 members.

The LB accepted the first three proposals and they are:

The proposals will pass through a stage of deliberation and then execution.

Language Boards Issues

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.
