Some things to think about: How do you create a description for a battleship that saw service with several different navies or a river that runs through several different countries? How do you create a description for a country that does not exist anymore or a location that has been destroyed? How do you create a description for a fictional person, item, place, etc., when Wikidata does not currently have an effective way of denoting that something is fictional? It might make sense to use Wikipedia categories to augment the Wikidata statements.
The "fictional" attribute has its specific pecularities. There are some doubtless cases where Wikipedia has categories indicating fictionality, e.g. "Lt. Commander Whorf" of Startrek, or "Pinocchio". How about "Atlantis"? fictional or real? Undecided? Even harder: "god": some in my neighborhood insist on "fictional", some others clearly vote for "real", some say "dunno", and there is the option to say "this question cannot be decided", isn't that fun? :-) The absence of a categorization as "fictional" does not imply anything. Yet it would be generally most useful to have an attribute, the value of which is one of "fictional, real, unknown, disputed," maybe more. For me, there is no obvious source to infer these values from, except "fictional" in many cases.
