Description

This ontology is partially based on the conceptual model for Quantities, Units, Dimensions, Values (QUDV) to define systems of units and quantities for use in system models proposed by a working group of the SysML 1.2 Revision Task Force (RTF), working in close coordination with the OMG MARTE specification group. This Model Library for Quantities, Units, Dimensions and Values (QUDV) is described in OMG SysMLTM, Version 1.2 Appendix C.4 Model Library for Quantity Kinds and Units http://ontolog.cim3.net/file/resource/reference/UoM_Ontology_Standard/available-UoM-references/QUDV-Annex-C4-C5--OMG-SysML-v1-2_Oct-2009.pdf (Note: the SYSML-QUDV definitions are flagged with a rdfs:seeAlso annotation equal to with http://www.omgsysml.org/qudv.

This ontology is developed as a complement to the Agriculture Meteorology example showcasing the ontology developed by the W3C Semantic Sensor Networks incubator group (SSN-XG). For more information on the group's activities see: http://www.w3.org/2005/Incubator/ssn/ .

Please report any errors to the Semantic Sensor Network Incubator Activity via the public W3C list public-xg-ssn@w3.org or alternatively, to the QUDV mailing list: http://www.omg.org/publicarchives/qudv/

Unit	ConversionBasedUnit	class	A ConversionBasedUnit is an abstract classifier that is a Unit that represents a measurement unit that is defined with respect to another reference unit through an explicit conversion relationship.
Unit	DerivedUnit	class	A DerivedUnit is a Unit that represents a measurement unit that is defined as a product of powers of one or more other measurement units. For example the measurement unit â€œmetre per secondâ€ for â€œvelocityâ€ is specified as the product of â€œmetreâ€ to the power one times â€œsecondâ€ to the power minus one
Unit	GeneralConversionUnit	class	A GeneralConversionUnit is a ConversionBasedUnit that represents a measurement unit that is defined with respect to another reference measurement unit through a conversion relationship expressed in some syntax through a general mathematical expression. The unit conversion relationship is defined by the following equation: valueRU / valueCU = f(valueRU, valueCU) where: valueRU is the quantity value expressed in the referenceUnit, and, valueCU is the quantity value expressed in the GeneralConversionUnit, and, f(valueRU, valueCU) is a mathematical expression that includes valueRU and valueCU.
Unit	LinearConversionUnit	class	A LinearConversionUnit is a ConversionBasedUnit that represents a measurement unit that is defined with respect to another measurement reference unit through a linear conversion relationship with a conversion factor. The unit conversion relationship is defined by the following equation: valueRU = factor Â· valueCU, where: valueRU is the quantity value expressed in the referenceUnit, and, valueCU is the quantity value expressed in the LinearConversionUnit.
Unit	Prefix	class	A Prefix represents a named multiple or submultiple multiplication factor used in the specification of a PrefixedUnit. A SystemOfUnits may specify a set of prefixes.
Unit	PrefixedUnit	class	A Prefix represents a named multiple or submultiple multiplication factor used in the specification of a PrefixedUnit. A SystemOfUnits may specify a set of prefixes.
Unit	SimpleUnit	class	A SimpleUnit is a Unit that represents a measurement unit that does not depend on any other Unit. Typically a base unit would be specified as a SimpleUnit.
Unit	Unit	class	A Unit is an abstract classifier that represents the [VIM] concept of â€œmeasurement unitâ€ that is defined as â€œreal scalar quantity, defined and adopted by convention, with which any other quantity of the same kind can be compared to express the ratio of the two quantities as a number.â€
Unit	UnitFactor	class	A UnitFactor represents a factor in the product of powers that defines a DerivedUnit.
Unit	prefix	property	Ordered set of Prefix that specifies the prefixes for multiples and submultiples of units in the system
Unit	referenceUnit	property	Specifies the unit with respect to which the ConversionBasedUnit is defined.
Unit	unit	property	Specification of the associated Unit.
Unit	unitFactor	property	Rational number that specifies the factor in the unit conversion relationship.
Unit	unitKind	property	Specification of the associated Unit "Kind".
Scale	Scale	class	A Scale represents the [VIM] concept of a â€œmeasurement scaleâ€ that is defined as an â€œordered set of quantity values of quantities of a given kind of quantity used in ranking, according to magnitude, quantities of that kind.â€ A Scale specifies one or more fixed values that have a specific significance in the definition of the associating QuantityKind. For example the â€œthermodynamic temperatureâ€ kind of quantity is defined by specifying the values of 0 and 273.16 kelvin as the temperatures of absolute zero and the triple point of water respectively. A Scale does not always need to specify a unit. For example the â€œRockwell C Hardness Scaleâ€ or the â€œBeaufort Wind Force Scaleâ€ are ordinal scales that do not have a particular associated unit. Similarly, subjective scales for a â€œpriorityâ€ or â€œriskâ€ kind of quantity with e.g. value definitions 0 for â€œlowâ€, 1 for â€œmediumâ€ and 3 for â€œhighâ€ do not have a particular associated unit.
Scale	ScaleValueDefinition	class	A ScaleValueDefinition represents a specific value for a measurement scale.
Scale	scale	property	Specification of a Scale that is associated to the QuantityKind.
Scale	scaleValueDefinition	property	Ordered set of ScaleValueDefinition that specifies the defined numerical value(s) and textual definition(s) for the measurement scale.
Quantity	DerivedQuantityKind	class	A DerivedQuantityKind is a QuantityKind that represents a kind of quantity that is defined as a product of powers of one or more other kinds of quantity. A DerivedQuantityKind may also be used to define a synonym kind of quantity for another kind of quantity. For example â€œvelocityâ€ can be specified as the product of â€œlengthâ€ to the power one times â€œtimeâ€ to the power minus one, and subsequently â€œspeedâ€ can be specified as â€œvelocityâ€ to the power one.
Quantity	QuantityKind	class	A QuantityKind is an abstract classifier that represents the [VIM] concept of â€œkind of quantityâ€ that is defined as â€œaspect common to mutually comparable quantities.â€ A QuantityKind represents the essence of a quantity without any numerical value or unit. Quantities of the same kind within a given system of quantities have the same quantity dimension. However, quantities of the same dimension are not necessarily of the same kind.
Quantity	QuantityKindFactor	class	A QuantityKindFactor represents a factor in the product of powers that defines a DerivedQuantityKind.
Quantity	SimpleQuantityKind	class	A SimpleQuantityKind is a QuantityKind that represents a kind of quantity that does not depend on any other QuantityKind. Typically a base quantity would be specified as a SimpleQuantityKind.
Quantity	SpecializedQuantityKind	class	A SpecializedQuantityKind is a QuantityKind that represents a kind of quantity that is a specialization of another kind of quantity. For example, â€œdistanceâ€, â€œwidthâ€, â€œdepthâ€, â€œradiusâ€ and â€œwavelengthâ€ can all be specified as specializations of the â€œlengthâ€ SimpleQuantityKind.
Quantity	dimension	property	Derived ordered set of Dimension. The actual dimension of a QuantityKind depends on the list of baseQuantityKind that are specified in an actual SystemOfQuantities, see the DerivedDimensions constraint.
Quantity	factorQuantityKind	property	Specification of the associated QuantityKind.
Quantity	generalQuantityKind	property	A generalization relationship between two kinds of quantities.
Quantity	quantityKind	property	Specification of the associated QuantityKind.
Quantity	quantityKindFactor	property	Rational number that specifies the factor in the quantity conversion relationship.
Quantity	specificQuantityKind	property	A specialization relationship between two kinds of quantities.
Dimension	Dimension	class	A Dimension represents the [VIM] concept of 'quantity dimension' that is defined as 'expression of the dependence of a quantity on the base quantities of a system of quantities as a product of powers of factors corresponding to the base quantities, omitting any numerical factor.' For example in the ISQ the quantity dimension of 'force' is denoted by dim F = LÃ¯Â¿Â½MÃ¯Â¿Â½T^2, where 'F' is the symbol for 'force', and 'L', 'M', 'T' are the symbols for the ISQ base quantities 'length', 'mass' and 'time' respectively. The Dimension of any QuantityKind can be derived through the algorithm that is defined in C.5.3.20 with SystemOfQuantities. The actual Dimension for a given QuantityKind depends on the choice of baseQuantityKind specified in a SystemOfQuantities.
Dimension	DimensionFactor	class	A DimensionFactor represents a factor in the product of powers that defines a Dimension.
Dimension	SystemOfQuantities	class	A SystemOfQuantities represents the [VIM] concept of 'system of quantities' that is defined as a 'set of quantities together with a set of non-contradictory equations relating those quantities'. It collects a list of QuantityKind that specifies the kinds of quantity that are known in the system. The International System of Quantities (ISQ) is an example of a SystemOfQuantities, defined in ISO 31 and ISO/IEC 80000.
Dimension	SystemOfUnits	class	A SystemOfUnits represents the [VIM] concept of 'system of units' that is defined as 'set of base units and derived units, together with their multiples and submultiples, defined in accordance with given rules, for a given system of quantities'. It collects a list of Unit that are known in the system. A SysML SystemOfUnits only optionally defines multiples and submultiples.
Dimension	baseDimension	property	A Reference to the QuantityKind that represents the base quantity dimension in the factor.
Dimension	baseQuantityKind	property	Ordered set of QuantityKind that specifies the base quantities of the system of quantities. This is a subset of the complete quantityKind list. The base quantities define the basis for the quantity dimension of a kind of quantity.
Dimension	baseUnit	property	Ordered set of Unit that specifies the base units of the system of units. A â€œbase unitâ€ is defined in [VIM] as a â€œmeasurement unit that is adopted by convention for a base quantity,â€ i.e. it is the (preferred) unit in which base quantities of the associated systemOfQuantities are expressed.
Dimension	dimensionFactor	property	Rational number that specifies the factor in the dimension conversion relationship.
Dimension	quantityComponent	property	Quantities attached to a system.
Dimension	systemOfQuantities	property	Reference to the SystemOfQuantities for which the units are specified.
Dimension	unitComponent	property	Ordered set of Unit that specifies the units that are known in the system.

A DerivedUnit is a Unit that represents a measurement unit that is 
defined as a product of powers of one or more other measurement units. 
For example the measurement unit â€œmetre per secondâ€ for â€œvelocityâ€ is 
specified as the product of â€œmetreâ€ to the power one times â€œsecondâ€ to 
the power minus one

Module Scale

Scale

A Scale represents the [VIM] concept of a â€œmeasurement scaleâ€ that is defined as an â€œordered set of quantity values of quantities of a given kind of quantity used in ranking, according to magnitude, quantities of that kind.â€ A Scale specifies one or more fixed values that have a specific significance in the definition of the associating QuantityKind. For example the â€œthermodynamic temperatureâ€ kind of quantity is defined by specifying the values of 0 and 273.16 kelvin as the temperatures of absolute zero and the triple point of water respectively. A Scale does not always need to specify a unit. For example the â€œRockwell C Hardness Scaleâ€ or the â€œBeaufort Wind Force Scaleâ€ are ordinal scales that do not have a particular associated unit. Similarly, subjective scales for a â€œpriorityâ€ or â€œriskâ€ kind of quantity with e.g. value definitions 0 for â€œlowâ€, 1 for â€œmediumâ€ and 3 for â€œhighâ€ do not have a particular associated unit.

that kind.â€ A Scale specifies one or more fixed values that have a 
specific significance in the definition of the associating QuantityKind. 
For example the â€œthermodynamic temperatureâ€ kind of quantity is defined 
by specifying the values of 0 and 273.16 kelvin as the temperatures of 
absolute zero and the triple point of water respectively. A Scale does 
not always need to specify a unit. For example the â€œRockwell C Hardness 
Scaleâ€ or the â€œBeaufort Wind Force Scaleâ€ are ordinal scales that do not 
have a particular associated unit. Similarly, subjective scales for a 
â€œpriorityâ€ or â€œriskâ€ kind of quantity with e.g. value definitions 0 for 
â€œlowâ€, 1 for â€œmediumâ€ and 3 for â€œhighâ€ do not have a particular 
associated unit.

Module Dimension

Dimension

A Dimension represents the [VIM] concept of 'quantity dimension' that is defined as 'expression of the dependence of a quantity on the base quantities of a system of quantities as a product of powers of factors corresponding to the base quantities, omitting any numerical factor.' For example in the ISQ the quantity dimension of 'force' is denoted by dim F = LÃ¯Â¿Â½MÃ¯Â¿Â½T^2, where 'F' is the symbol for 'force', and 'L', 'M', 'T' are the symbols for the ISQ base quantities 'length', 'mass' and 'time' respectively. The Dimension of any QuantityKind can be derived through the algorithm that is defined in C.5.3.20 with SystemOfQuantities. The actual Dimension for a given QuantityKind depends on the choice of baseQuantityKind specified in a SystemOfQuantities.
