In the IRIS network of excellence [1], one work package (”Authoring Tools and Creation Methods”) has been tackling accessibility issues of highly-interactive and generative Interactive Storytelling (IS) systems for story creators. While one problem is a current lack of well-designed tools, which needs improvement, the other side of the medal is that nevertheless, prospective interactive storyworld creators need basic knowledge in the currently available approaches. With the vision in mind that in the future, complex IS projects will be accomplished by an interdisciplinary team, future authors do not need to program a story engine, but they would indeed need to know about the characteristics of content conceptualization, knowledge modeling and forms of abstraction, which then are used in a collaborative production process with engineers.
