We publish on our digital library a collection of documents containing lyrics of folk songs from Bretagne (France). The titles of the songs are filled in the dc:subject with as many input required (12 songs in the document = 12 dc:subject inputs) (see Chansons et autres pièces contenues dans le(s) document(s) on Documents envoyés par Claude Le Prat au concours du Barzaz Bro-Leon).
The songs have to be filled in order of appearance in the documents. However, one could make a mistake and forget a song. So that if we miss the 5th song on 13, we have to create an new dc:title input an copy-paste 8 song titles.
Is there a way to reorder the inputs as it is possible to reorder item of a collection with Item Order plugin ?
