Our work guidelines specifically say not to use scenes as works for operas (it’s different for ballets though, and it might make sense to add that for ballets in the future).
We should be able to order all the relationships in the same way as now - might require a small code change but it shouldn’t be too hard.
Agreed, but that I can’t promise just yet
I’d want them to look pretty much the same as now at first, with any changes we decide we want while testing the stuff coming after that. So attributes would be shown in the pages after or before each part (ideally in a way in which they won’t break the parts list display, which again might require some coding work) and they would be shown as part of the attribute list in the XML like for member-of here).
Honestly, you might have a better idea than I do at this point - I haven’t really tried to use works much in the WS.
