Concept: Open

System documentation


Superconcept: Unblock

Definition: Open a Portal in a Barrier so that things can Move-Through it.

Required Relationships:

object: The Spatial-Entity that is Open'ed and takes on the role of a Portal. This action changes the state of the object, from Be-Closed to Be-Open.

Other Common Relationships:

agent: the entity that causes this action
instrument: the entity that played the role of Portal-Covering before the Portal was Opened. This action causes the entity to no longer play that role.
Comment: The slots used to describe Make-Accessible actions in general can be used here, too. For example, destination and by-means-of.

Examples:

  1. John opened the door.
    object: the doorway
    agent: John
    instrument: the door
  2. Comment: The doorway becomes a Portal, and the door ceases to be a Portal-Covering.
  3. John opened the window with a screwdriver.
    agent: John
    object: the space inside the window frame
    instrument: a screwdriver
  4. Comment: The space inside the window frame becomes a Portal, and the window (the glass itself) ceases to be a Portal-Covering.
