Benny,Nice. Following up on that: Do you think it's possible to split the other attributes between Gramps repository, source and citation objects too? I mean, author and title are source fields, page is citation, so they are quite clear, but URL is a difficult one, as it may be a site URL, source URL, or record URL.
4/note also that for repository and repo location, I intend to use the actual first repository connected to the source, not an attribute stored.
Tim brought it up, and Simple Citations splits the attributes between Master Source and Source Details too, and I think I can make a similar split for most fields of our current CSV. It will result in yet another column in that CSV, but I'm prepared to put some effort in this anyway.
