Veracity is the ability to be true. Veracity is the property of
truthfulness? $thing has veracity. $thing's veracity is true.
An object environment I prototyped a few years ago used something
similar. There were five levels of objects:
Level 0 object:
object (the fundamental building block of the universe)
Level 1 objects:
aspect (a reusable property for templates) is an object
template (an intangible, ideal object) is an object
Aspects (level 2):
clothing (the ability to be worn) is an aspect
containable (the ability to be somewhere) is an aspect
container (the ability to contain things) is an aspect
lidded (the ability to be sealed) is an aspect
owner (the ability to own something) is an aspect
posession (the ability to be owned) is an aspect
session (the ability to service connections) is an aspect
shell (the ability to parse commands) is an aspect
tcpd (the ability to accept tcp socket connections) is an aspect
etc.
Templates (level 3):
actor (a base class for players) is a template with container,
containable, session and shell properties.
container (an ideal tangible container) is a template having
container properties.
lidded container (an ideal sealable container) is a template having
container and lidded properties.
login daemon (something which answers remote connections and
authenticates identities) is a template having tcpd properties.
thing (an ideal tangible object) is a template with containable and
posession properties.
etc.
Real tangible objects (level 4):
the login server is a login daemon
rocco is an actor
rocco's backpack is a lidded container
schwern is an actor
schwern's pants are clothing
schwern's fish is a thing
etc.
Hmm... perhaps I should include magic clothing: a template with
clothing, container and lidded properties.
