Description
This Model Library for Quantities, Units, Dimensions and Values (QUDV) (Note: in the ontology, the SYSML-QUDV definitions are flagged with a rdfs:seeAlso annotation equal to http://www.omgsysml.org/qudv).
This ontology is partially based on the SysML QUDV (Quantities, Units, Dimensions and Values) 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 is specified in a UML/SysML class/block diagram in the OMG SysML, Version 1.2 specification (http://www.omg.org/spec/SysML/1.2/). This model is described in OMG SysML, 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). The QUDV model has also been represented in the form of an ontology using a formal ontology definition language. The resulting OWL ontology, called the QUDV ontology http://www.omgwiki.org/OMGSysML/doku.php?id=sysml-qudv:qudv_owl has been published by members of the QUDV working group of the SysML 1.2 Revision Task Force (RTF). OMG SysML is a trademark of OMG (see http://www.omg.org/spec/SysML/1.2/PDF/ for the conditions of use of the OMG SysML, Version 1.2 specification).
In order to generalize its potential usage and alignment with other standardization efforts concerning quantities and units, the QU ontology has been further developed as a complement to the Agriculture Meteorology example showcasing the ontology developed by the W3C Semantic Sensor Networks incubator group (SSN-XG). The Agriculture Meteorology example also includes an application of the QU schema to the UN/CEFACT Recommendation 20 code list. 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, for enquiries about the QUDV model, to the QUDV mailing list: http://www.omg.org/publicarchives/qudv/

Data name property
Data numericalValue property Specifies the numerical value.
Data symbol property Short symbolic name.
Data symbolicExpression property Symbolic expression of the quantity dimension's product of powers, in terms of symbols of the kinds of quantity that represent the base kinds of quantity and their exponents.
Data unitMultipleFactor property Specifies the multiple or submultiple multiplication factor.
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 "metre per second" for "velocity" is specified as the product of "metre" to the power one times "second" 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 · 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 "measurement unit" that is defined as "real 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."
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 "measurement scale" that is defined as an "ordered set of quantity values of quantities of a given kind of quantity used in ranking, according to magnitude, quantities of that kind." A Scale specifies one or more fixed values that have a specific significance in the definition of the associating QuantityKind. For example the "thermodynamic temperature" 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 "Rockwell C Hardness Scale" or the "Beaufort Wind Force Scale" are ordinal scales that do not have a particular associated unit. Similarly, subjective scales for a "priority" or "risk" kind of quantity with e.g. value definitions 0 for "low", 1 for "medium" and 3 for "high" 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 "velocity" can be specified as the product of "length" to the power one times "time" to the power minus one, and subsequently "speed" can be specified as "velocity" to the power one.
Quantity PropertyKind class A PropertyKind is a meta-property which helps to characterise categories of properties e.g. scalar, vector
Quantity QuantityKind class A QuantityKind is an abstract classifier that represents the [VIM] concept of "kind of quantity" that is defined as "aspect common to mutually comparable quantities." 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, "distance", "width", "depth", "radius" and "wavelength" can all be specified as specializations of the "length" 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 propertyType property Specification of the associated ProeprtyType.
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 = L�M�T^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 "base unit" is defined in [VIM] as a "measurement unit that is adopted by convention for a base quantity," 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.

Module Scale

Scale

A Scale represents the [VIM] concept of a "measurement scale" that is defined as an "ordered set of quantity values of quantities of a given kind of quantity used in ranking, according to magnitude, quantities of that kind." A Scale specifies one or more fixed values that have a specific significance in the definition of the associating QuantityKind. For example the "thermodynamic temperature" 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 "Rockwell C Hardness Scale" or the "Beaufort Wind Force Scale" are ordinal scales that do not have a particular associated unit. Similarly, subjective scales for a "priority" or "risk" kind of quantity with e.g. value definitions 0 for "low", 1 for "medium" and 3 for "high" do not have a particular associated unit.

A Scale represents the [VIM] concept of a "measurement scale" that is 
defined as an "ordered set of quantity values of quantities of a given 
kind of quantity used in ranking, according to magnitude, quantities of 
that kind." A Scale specifies one or more fixed values that have a 
specific significance in the definition of the associating QuantityKind. 
For example the "thermodynamic temperature" 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 "Rockwell C Hardness 
Scale" or the "Beaufort Wind Force Scale" are ordinal scales that do not 
have a particular associated unit. Similarly, subjective scales for a 
"priority" or "risk" kind of quantity with e.g. value definitions 0 for 
"low", 1 for "medium" and 3 for "high" do not have a particular 
associated unit.

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 "velocity" can be specified as the product of "length" to the power one times "time" to the power minus one, and subsequently "speed" can be specified as "velocity" to the power one.

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 = L�M�T^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.
