Children 
absorbedDose  The amount of energy imparted by nuclear (or ionizing) radiation to unit mass of absorbing material. The unit is the rad. 
 age  Simply relates an Object to a ConstantQuantity specifying the age of the Object. 
 airTemperature  (airTemperature ?AREA ?TEMP) means that the temperature of the air at ?AREA is ?TEMP. Temperature may be expressed in units of TemperatureMeasure, including CelsiusDegree and FahrenheitDegree, among others. 
 barometricPressure  (barometricPressure ?AREA ?PRESSURE) means that the atmospheric pressure measured at ?AREA is ?PRESSURE. Barometric pressure is typically expressed in units of InchMercury or MmMercury. For example, standard sea level pressure is 29.92 inches (760 mm) of mercury: (barometricPressure SeaLevel (MeasureFn 29.92 InchMercury)). 
 effectiveRange  Models 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). 
 fleetDeadWeightTonnage  (fleetDeadWeightTonnage ?FLEET ?AMOUNT) means that the Collection of Ships ?FLEET has a total carrying capacity of ?AMOUNT in LongTons. This is the total vesselDeadWeightTonnage of all the vessels combined. Dead Weight Tonnage, or DWT, is the weight of cargo plus stores that a vessel can carry when immersed to the proper load line. 
 fleetGrossRegisteredTonnage  (fleetGrossRegisteredTonnage ?FLEET ?AMOUNT) means that the Collection of Ships ?FLEET has a total carrying capacity of ?AMOUNT in RegistryTons. This is the total vesselGrossRegisteredTonnage of all the vessels combined. Gross Registered Tonnage, or GRT, is the capacity of a vessel calculated on an equivalence of 100 cubic feet of sheltered area per ton. 
 linearExtent  BinaryPredicate that is used to state the measure of an Object from one point to another point along its surface. 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. 
 loudness  
 memorySize  (memorySize ?System ?Size) holds if ?Size is the required memory size for the ComputationalSystem ?System. 
 phMeasure  
 significantWaveHeight  significantWaveHeight is a TernaryPredicate. (significantWaveHeight ?WA ?TIME ?SWH) ?SWH is a LengthMeasure used to describe the average wave height, from trough to crest, of the highest third the waves for a ?WA (WaterArea) for a ?TIME (TimeInterval). It is defined as four times the standard deviation of the height of all waves. 
 trackWidth  The distance between the two rails of a Railway. 
 vesselDisplacement  (vesselDisplacement ?VESSEL ?AMOUNT) means that the displacement of WaterVehicle ?VESSEL is the PhysicalQuantity ?AMOUNT. The displacement of a vessel may be measured in LongTons (Dead Weight Tonnage, or DWT) or by volume (Gross Registered Tonnage, or GRT). 
 weight  (weight ?O ?MM) means that on planet earth the SelfConnectedObject ?O has the weight ?MM. 
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. 
 AntisymmetricRelation  BinaryRelation ?REL is an AntisymmetricRelation if for distinct ?INST1 and ?INST2, (?REL ?INST1 ?INST2) implies not (?REL ?INST2 ?INST1). In other words, for all ?INST1 and ?INST2, (?REL ?INST1 ?INST2) and (?REL ?INST2 ?INST1) imply that ?INST1 and ?INST2 are identical. Note that it is possible for an AntisymmetricRelation to be a ReflexiveRelation. 
 AsymmetricRelation  A BinaryRelation is asymmetric if and only if it is both an AntisymmetricRelation and an IrreflexiveRelation. 
 BinaryPredicate  A Predicate relating two items  its valence is two. 
 BinaryRelation  BinaryRelations are relations that are true only of pairs of things. BinaryRelations are represented as slots in frame systems. 
 Entity  The universal class of individuals. This is the root node of the ontology. 
 InheritableRelation  The class of Relations whose properties can be inherited downward in the class hierarchy via the subrelation Predicate. 
 IrreflexiveRelation  Relation ?REL is irreflexive iff (?REL ?INST ?INST) holds for no value of ?INST. 
 Predicate  A Predicate is a sentenceforming 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 BinaryPredicates, 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. Predicates and Functions both denote sets of ordered ntuples. The difference between these two Classes is that Predicates cover formulaforming operators, while Functions cover termforming operators.
