Why does ObjectAid not support XMI?
XMI is an exchange format for UML models. However, for ObjectAid the model is the actual Java source code itself. Currently ObjectAid does not have modeling capabilities; instead, it offers a graphical view of existing source code. Therefore XMI import/export does not make sense for ObjectAid. Once ObjectAid gets actual modeling capabilities, it will store its UML model as XMI.
