single valued relation
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 SingleValuedRelations are TotalValuedRelations.
Relationships      
Parents inheritable relation The class of Relations whose properties can be inherited downward in the class hierarchy via the subrelation Predicate.
  relation The Class of relations.There are two kinds of Relation: Predicate and Function. Predicates and Functions both denote sets of ordered n-tuples. The difference between these two Classes is that Predicates cover formula-forming operators, while Functions cover term-forming operators.
Children functionA Function is a term-forming Relation that maps from a n-tuple of arguments to a range and that associates this n-tuple with at most one range element. Note that the range is a Class, and each element of the range is an instance of the Class.
Instancesabsolute heightThe height of an aircraft directly above the surface or terrain over which it is flying.
 ageSimply relates an Object to a ConstantQuantity specifying the age of the Object.
 altitudeA TernaryPredicate that is used to state the distance between the top of an Object and another point that is below 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 height of geographic features, e.g. mountains, the altitude of aircraft, and the orbit of satellites around the Earth.
 amplifier efficiencyProportion of a energy of the Amplifier output signal to the energy used by that Amplifier.
 annual energy consumptionThe estimated amount of energy consumed by a device during one year.

 arc weightThis predicate indicates the value of a GraphArc in a Graph. This could map to the length of a road in a road network or the flow rate of a pipe in a plumbing system.
 averageA partial function that relates a List to a RealNumber, provided that the List only has list elements that are RealNumbers. The RealNumber associated with the List is equal to the mathematical average of the RealNumbers in the List divided by the total number of list elements.
 average charger energy ratioAverage proportion of energy obtained by a Battery to the total energy used by a BatteryCharger while charging that battery.
 clothes washer modified energy factor(MEF) Capacity of clothes divided by sum of mechanical energy per cycle and water heating energy per cycle and drying energy. The higher the more efficient.

 depthA TernaryPredicate that is used to state the distance between the bottom of an Object and another point that is above the bottom of the Object (often this other point will be SeaLevel). Note that this Predicate can be used to specify, for example, the depth of marine life or submarines.
 diameter(diameter ?CIRCLE ?LENGTH) means that the diameter of the Circle ?CIRCLE has a length of ?LENGTH.
 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.
 effective rangeModels the effective range of some device that is able to move by itself (like vehicles, rockets and so on) or move other things (like weapons).
 electron number(electronNumber ?SUBSTANCE ?NUMBER) means that the PureSubstance ?SUBSTANCE has the number of Electrons ?NUMBER.

 fatherThe general relationship of fatherhood. (father ?CHILD ?FATHER) means that ?FATHER is the biological father of ?CHILD.
 fresh food compartment volumeThe volume of the fresh food compartment in a Refrigerator.
 frozen food compartment volumeThe volume of the froozen food compartment in a Freezer.
 genetic substrate of virus(geneticSubstrateOfVirus ?VIRUS ?MOL) relates the virus ?VIRUS to the molecule ?MOL that contains its genetic information.
 geometric distance(geometricDistance ?POINT1 ?POINT2 ?LENGTH) means that ?LENGTH is the distance between the two GeometricPoints ?POINT1 and ?POINT2.
 human capacity(humanCapacity ?CONSTRUCT ?NUMBER) means that the StationaryArtifact ?CONSTRUCT, e.g. a Building or a Room, can hold a maximum of ?NUMBER Humans without crowding.
 idle power consumptionThe average power used by a device while it is in idle state.
 intelligence quotient(intelligenceQuotient ?PERSON ?NUMBER) means that ?NUMBER is the I.Q. of ?PERSON. The I.Q. of a person is the ratio of their mental age (determined by a standardized test) divided by their chronological age, multiplied by 100.
 invading virus(invadingVirus ?CELLINV ?VIRUS) means that ?VIRUS is a virus that invades a host cell in the cell invasion ?CELLINV. If the invasion results in a replication, it is the genome of the invading virus that is replicated. The original virus is destroyed but replicated in the process.
 leader(leader ?INSTITUTION ?PERSON) means that the leader of ?INSTITUTION is ?PERSON.
 lengthBinaryPredicate that is used to state the measure of an Object along its longest span.
 maximum clothes volumeHighest possible voulme of cothes processedn in a single LaundryAppliance run.
 maximum spin speedHighest possible frequency of a tumble spin in a TumbleDryer.
 monetary valueA BinaryPredicate that associates an Object or Process with its value expressed as an instance of CurrencyMeasure.
 motherThe general relationship of motherhood. (mother ?CHILD ?MOTHER) means that ?MOTHER is the biological mother of ?CHILD.
 net worthTotal assets minus total liabilities of an individual or company.

 spin drying performance classEuropeanUnionEnergyLabelClass given for a LaundryAppliance for its drying performance only.
 string concatenate fnThe result of applying this Function to two SymbolicString arguments is a third SymbolicString that is the concatenation of the two arguments. Example: (equal "Charles Darwin" (StringConcatenateFn "Charles " "Darwin")).
 string concatenation(stringConcatenation ?SymbolicString-1 ?SymbolicString-2 ?SymbolicString-3) means that ?SymbolicString-3 can be formed by appending ?SymbolicString-1 and ?SymbolicString-2, in order. Example: (stringConcatenation "Charles " "Darwin" "Charles Darwin") is a True Sentence.
 string length(stringLength ?NonnegativeInteger ?SymbolicString) means that the number of Characters in ?SymbolicString is ?NonnegativeInteger. Example: (stringLength 14 "Charles Darwin"), which is a True Sentence.
 string length fnThis UnaryFunction takes a SymbolicString as its sole argument. The result of evaluating a term formed with StringLengthFn is a NonnegativeInteger that denotes the number of Characters in the SymbolicString. Example: (equal 14 (StringLengthFn "Charles Darwin")).
 substring fn(SubstringFn ?SymbolicString ?NonnegativeInteger-1 ?NonnegativeInteger-2) denotes a string that is a subString of ?SymbolicString, begins with the Character at the index ?NonnegativeInteger-1, and ends with the Character at the index (SubtractionFn ?NonnegativeInteger-2 1). The first Character in ?SymbolicString is denoted by the index 0. If the value of ?NonnegativeInteger-1 or ?NonnegativeInteger-2 is greater than the value of (StringLengthFn ?SymbolicString), or if ?NonnegativeInteger-1 is greater than ?NonnegativeInteger-2, the result of evaluating the SubstringFn expression is undefined. Example: (equal "Charle" (SubstringFn "Charles Darwin" 0 6)).
