Basing at information about differences (Sword protocol errors due to export to SHERPA/ROMEO - #11 by brianh) beetween SWORD protocol and SHERPA\ROMEO api, maybe it will be cool to create plugin for sherpa export
full doc for sherpa is here: http://www.sherpa.ac.uk/romeo/SHERPA%20RoMEO%20API%20V-2-9%202013-11-25.pdf
also some information is here: sherpa.ac.uk/romeo/apimanual.php
