I've been busy and have been extracting all the characters of Atlas Shrugged from the topic 'List of Characters in Atlas Shrugged' (http://www.freebase.com/view/en/characters_in_atlas_shrugged)
However, there are a couple of characters (listed at the bottom of the wikipedia article) who never appeared in the published work. They were cut by the author and are irrelevant to the final story.
How do I represent their unpublished/cut status?
Should I be adding them to the book's fictional universe?
I wouldn't add them myself. We do include deleted scene performances in films but do not attempt to capture in Freebase performances planned but never written/performed/filmed, that's datum that is just too nebulous and conceptual. I would consider including characters and concepts that were in a published work that were edited out in subsequent editions.
If you really feel it is important to capture this, you could create a new type for Unrealized Fictional Character and have as an enumerated property the status: edited out/never written/occurs in work destroyed/unsubstantiated claim...
