We need to resolve the differences between the KAR file format and the module format because we have two different ways of storing very similar information. This relates to bugs 1750 and 4317. It would be nice if a kar file could include all of the same information as a module so that modules can be transported in similar ways as kars. The kar import/export system needs to know how to process actors and workflows as well as the jars/classes that they depend on.
