Value_False : is_instance_of : Boolean_Value

This item is provide for use as the object of connections that express a simple (true or false) fact. For example, "Value_False" is the object of the connection "BettyTheCat hasFleas Value_False".

This relationship is used to connect one item with a second item representing the class of which the first item is a member. For example, the connection "QueenMary is_instance_of Ships" states that the Queen Mary is a ship, and allows the system to apply all of the rules that pertain to instances of "Ships" to the "QueenMary" item, and allows the "QueenMary" item to be referenced from contexts that require a member of "Ships". # fundamental property classes; the root of the property universe

This item represents a particular type of constant value that can be used as the object of connections. For example, in the statement "SallySinger paysTaxesOnTime-Is 'True'", "true" is the Boolean constant object of the connection. Sometimes the value of a Boolean-type constant can be input by selecting a specific web-page control, and other types it has to be typed into a text-entry box. When typed, only the words "true" or "false" should be used, although the capitalization ("true", "True", "TRUE") doesn't matter. In addition, for connections that use properties that express a true/false state but whose objects are Items rather than constants, the system provides the built-in Items "Value_True" and "Value_False" that can be selected as a relationship's object.
