      The code seems to work just fine (tested). My only problem is that
      I'm getting a warning about $p_default when reloading the repo,
      which I am not sure where it's referring to, so if you have any
      hints it would be great. The warnings are:<br>
      <br>
      $ ./bin/epadmin reload myrepo<br>
      Use of uninitialized value $p_default in string eq at
      /usr/share/eprints3/bin/../perl_lib/EPrints/MetaField.pm line 211.<br>
      Use of uninitialized value $p_default in string eq at
      /usr/share/eprints3/bin/../perl_lib/EPrints/MetaField.pm line 213.<br>
      Use of uninitialized value $p_default in string ne at
      /usr/share/eprints3/bin/../perl_lib/EPrints/MetaField.pm line 217.<br>
      defined(@array) is deprecated at
      /usr/share/eprints3/lib/plugins/EPrints/Plugin/Screen/BulkAction/Remove.pm
      line 46.<br>
          (Maybe you should just omit the defined()?)<br>
      <br>
      <br>
      Thanks again for all the help!! As far as multilingual fields is
      concerned I think we're really getting there! Any other problems
      (like the import problem that arose) that someone foresees are
      welcome, so as to address them before making the bazaar package
      (and updating the wiki).<br>

                                          order to use to solve my

                                          I'll speak my thoughts out

                                          I'm wrong. Let the target
                                          field be the "title".<br
                                            class="">
                                          <br class="">
                                          So, we need the title to be
                                          stored in more than one
                                          languages in the database,
                                          which should be "easily"
                                          accomplished using a multi-row
                                          field. Hence, multilang fields
                                          are a perfect candidate for
                                          this. We therefore create a
                                          new field, let's say ml_title
                                          (as you proposed) and store
                                          our values in it. Now, in
                                          order for EPrints not to
                                          break, we change the title
                                          field to be a virtual field
                                          and compose its output based
                                          on ml_title field. In the end,
                                          we'll have two fields for the
                                          title. The title field (of
                                          type virtualfield) that will
                                          be calculating its value each
                                          time it's called, and the
                                          ml_title field (of type
                                          multilang). Is that correct?<br

                                            already does stuff like this
