It appears that there are items which have values for that field. DSpace (or rather, the DBMS at DSpace's direction) is correctly preventing you removing the definition of a field which is still in use. You'd need to edit all of those items and remove the field value(s). If you're comfortable with operating directly on the database, you could back it up and run a query to delete all rows from the "metadatavalue" table which have the "id" of that field in the "metadata_field_id" column. Or you could write a curation task to hunt down those items and remove the relevant field value(s). -- Mark H. Wood, Lead System Programmer mw...@iupui.edu There's an app for that: your browser
