@blankdots what about XML uploads? Those show in the listing too but I think edit functionality would be weird since only option would be to replace the file. I suggest that we show only delete button on XML submissions. This requires #94 so we can get submission type for metaDataObjects.

yes, XML uploads probably the only way to edit would be to re-upload, but not sure we offer a PUT for XML but not PATCH so we can patch form, meaning edit data but for XML we will replace it. and maybe the labels should reflect that.
