The document discusses the concepts of openness, open licensing, and open source in the digital age. It notes that traditional intellectual property regulation was made for analog times with limited distribution, while digital times enable many authors and unlimited copying. Various degrees of openness are discussed, from content not being available online to public domain with no rights reserved. Creative Commons licenses provide options from attribution to share-alike.
