| http://www.w3.org/ns/prov#value | - Non-fiction authors are required to have what is known as a ???platform??? for their work, before their books are even published. (Non-fiction is typically harder to sell, unless the author is a celebrity or the topic is controversial, so having a ready-made audience before being published would hopefully sell more books.) A platform can consist of a blog or website, a Facebook page or Twitter fee
