The remainder of a package name should consist of one or more components describing the package. Components should be short, generally eight or fewer characters. Meaningful abbreviations are encouraged, for example, util rather than utilities. Acronyms are acceptable, for example, awt. Components should generally consist of a single word or abbreviation.
But what about when a package component is multi-word? I haven't found any good stated convention for multi-word components (for example, "com.example.ui.viewmodel" vs "com.example.ui.view_model"; I know most tend toward the former).
