I think the interface should use Java generics to allow compile time data type checking. I think everywhere were we currently use the Java collection API we should use generics. Thus, replace <i>java.util.List</i> use <i>java.util.List<org.jdom.Element></i>. This will require that DSpace be compiled with a Java 1.5 compiler (However an older jvm, such as 1.4, will still be able to exceute the bytecode). – ScottPhillips
