System documentation


Superconcept: Thing

Definition: A Role is the name given to an Entity when it's participating in an Event. Examples include Barrier, Container, and Product, in which the Entity "playing the role" is participating in the Events of Block, Be-Contained, and Produce, respectively. More information on Roles, including the ways in which Roles differ from Entities and the way to represent Roles in SHAKEN, will be forthcoming.

Required Relationships:

played-by: the Entity that plays the Role
in-event: the Event that that Entity participates in

Examples:

  1. The philanthropist gave his stock certificates to charity.

  2. He used a rock to hit the nail.
