Relationships
Instances
Abstract
Properties or qualities as distinguished from any particular embodiment of the properties/qualities in a physical medium. Instances of Abstract can be said to exist in the same sense as mathematical objects such as sets and relations, but they cannot exist at a particular place and time without some physical encoding or embodiment.
Entity
The universal class of individuals. This is the root node of the ontology.
InheritableRelation
The class of
Relation
s whose properties can be inherited downward in the class hierarchy via the
subrelation
Predicate
.
Predicate
A
Predicate
is a sentence-forming
Relation
. Each tuple in the
Relation
is a finite, ordered sequence of objects. The fact that a particular tuple is an element of a
Predicate
is denoted by '(*predicate* arg_1 arg_2 .. arg_n)', where the arg_i are the objects so related. In the case of
BinaryPredicate
s, the fact can be read as `arg_1 is *predicate* arg_2' or `a *predicate* of arg_1 is arg_2'.
QuaternaryPredicate
The
Class
of
Predicate
s that require four arguments.
QuaternaryRelation
QuaternaryRelation
s relate four items. The two
subclass
es of
QuaternaryRelation
are
QuaternaryPredicate
and
TernaryFunction
.
Relation
The
Class
of relations. There are two kinds of
Relation
:
Predicate
and
Function
.
Predicate
s and
Function
s both denote sets of ordered n-tuples. The difference between these two
Class
es is that
Predicate
s cover formula-forming operators, while
Function
s cover term-forming operators.
