/**
 * A Module object represents a row in the modules view.

 * Two attributes are mandatory: an id identifies a module in the modules view and is used in a ModuleEvent for
 * identifying a module for adding, updating or deleting.
 * <p>
 * The name is used to minimally render the module in the UI.
 * <p>
 * 
 * <p>
 * Additional attributes can be added to the module. They will show up in the module View if they have a
 * corresponding ColumnDescriptor.
 * <p>
 * 
 * <p>
 * To avoid an unnecessary proliferation of additional attributes with similar semantics but different names
 * <p>
 * we recommend to re-use attributes from the 'recommended' list below first, and only introduce new attributes if
