Intro

Context

A supporting term for the messages.

An intersection of Time and Place in which Entities may play roles.

Comments

Scope: A Context is an Entity derived from the two primitives of Time and Place and a verb. A basic Context comprises only a Time and a Place (e.g., 'Here and Now', or '10.15 pm on July 31st 1984 in London'). However, most Contexts involve one or more other Entities playing roles as Resources, where the nature of the roles played by the Resources is determined by one or more verbs which underpin the Context and describe its characteristic behavior.

Example: Releasing a Product in France on May 5th 2005 is an Event; a Product being available for sale in France from May 5th 2005 until December 25th 2005 is a State.
