[Data-modeling] Are Influence Nodes necessarily persons?

[Tadhg O'Higgins]

Would Influence Node be more useful/interesting if it didn't assume 
personhood for its instances? Books, Films, Games, and Musical Groups 
are all examples of things that seem like Influence Nodes but are not 
persons.

We should consider removing the /people/person included type from 
Influence Node for that reason. The alternatives I can see are to a) 
create an "Influence <thing>" in each domain that might support one, or 
b) create an "Influence Thing" type that's just like Influence Node but 
doesn't include personhood. Neither of those seem as good a solution as 
widening the scope of Influence Node.

Thoughts?
