This looks like a large scale domain modelling problem for the movie production process. This is the last place I was expecting an overlap between computer engineering and film-making.

But it is not surprising given that large parts of film-making are now supported by software, which has a tendency to direct the evolution of terminology and concepts.

After a cursory glance at the model, it starts with a fairly generic set of primitives: Task, Asset, Participant, Context and Relationship. It then creates further instances based on this idea.

I'm sure other industries could also benefit from collaborative modelling of their problem domains like this.
