XMI Export Import

Is there an xmi import/export feature available? Or any way I can create an ER diagram based on UML created in Eclipse via Eclipse Papyrus which has an XMI export option?
It would be great to use eclipse for end to end modeling from UML to ER Diagram to DDL. Eclipse Modeling Framework does give good ways to do high level UML modeling. How can I integrate that input with another eclipse plugin like DBeaver ...XMI is the common format to exchange data.
