I have a number of columns in a table (xlsx) which describe the relationship between an artist and the subject of the piece (e.g. child, parent, spouse, friend,...) the data in the column is either 'x' or empty. I'm having trouble conceptualizing the best import process. I would like for them to appear as a checklist in the UI which would imply a list. Do I do that as a refinery or can it be done directly through CA_table.element? OTOH conceptually these are relations between two entities which is simpler to think about importing using a refinery to make the relationships but harder to think about how it appears in the UI.
