Removing types
- The default types are in file opt/eprints3/archives/ARCHIVEID/cfg/namedsets/eprint, edit it accordingly.
- Edit corresponding entries in /opt/eprints3/archives/ARCHIVEID/cfg/lang/en/phrases/eprint_types.xml (It might be no harm to leave them there.)
- Restart apache
Thanks for the help and hints from Ian Stuart.
