distance
(
distance
?OBJ1 ?OBJ2 ?QUANT) means that the shortest distance between the two objects ?OBJ1 and ?OBJ2 is ?QUANT. Note that the difference between the predicates
length
and
distance
is that the
length
is used to state the
LengthMeasure
of one of the dimensions of a single object, while
distance
is used to state the
LengthMeasure
that separates two distinct objects.
Relationships
Children
depth
A
TernaryPredicate
that is used to state the
distance
between the
top
of an
Object
and another point that is above the
top
of the
Object
(often this other point will be sea level). Note that this
Predicate
can be used to specify, for example, the depth of marine life or submarines, for example.
Instances
abstrait
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.
entit�
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
.
predicat
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'.
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.
relation simple
A
Relation
is a
SingleValuedRelation
just in case an assignment of values to every argument position except the last one determines at most one assignment for the last argument position. Note that not all
SingleValuedRelation
s are
TotalValuedRelation
s.
relation spatial
The
Class
of
Relation
s that are spatial in a wide sense. This
Class
includes mereological relations and topological relations.
pr�dicat ternaire
The
Class
of
Predicate
s that require exactly three arguments.
relation ternaire
TernaryRelation
s relate three items. The two
subclass
es of
TernaryRelation
are
TernaryPredicate
and
BinaryFunction
.
relation total
A
Relation
is a
TotalValuedRelation
just in case there exists an assignment for the last argument position of the
Relation
given any assignment of values to every argument position except the last one. Note that declaring a
Relation
to be both a
TotalValuedRelation
and a
SingleValuedRelation
means that it is a total function.
