Preflabel ConventionalProperty
Elucidation A quantitative property attributed by agreement to a quantity for a given purpose.
Example The thermal conductivity of a copper sample in my laboratory can be assumed to be the conductivity that appears in the vendor specification. This value has been obtained by measurement of a sample which is not the one I have in my laboratory. This conductivity value is then a conventional quantitiative property assigned to my sample through a semiotic process in which no actual measurement is done by my laboratory.

If I don't believe the vendor, then I can measure the actual thermal conductivity. I then perform a measurement process that semiotically assign another value for the conductivity, which is a measured property, since is part of a measurement process.

Then I have two different physical quantities that are properties thanks to two different semiotic processes.

Annotations
Comment The current version of EMMO does not provide explicit classes for physical dimensions. Rather it embraces the fact that the physical dimensionality of a physical quantity is carried by its measurement unit.

The role of dimensional unit and its subclasses is to express the physical dimensionality that is carried by the unit.

Since the dimensionality of a physical quantity can be written as the product of powers of the physical dimensions of the base quantities in the selected system of quantities, the physical dimensionality of a measurement unit is uniquely determined by the exponents. For a dimensional unit, at least one of these exponents must be non-zero (making it disjoint from dimensionless units).

Comment A symbolic is recognized as reference unit also if it is not part of a quantity (e.g. as in the sentence "the Bq is the reference unit of Becquerel").
For this reason we can't declare the axiom:
MetrologicalReference SubClassOf: inverse(hasMetrologicalReference) some Quantity
because there exist reference units without being part of a quantity.
This is peculiar to EMMO, where quantities as syntatic entities (explicit quantities) are distinct with quantities as semantic entities (properties).

Annotations
Comment Metrological uncertainty in EMMO is a slight generalisation of the VIM term 'measurement uncertainty', which is defined as "a non-negative parameter characterising the dispersion of the quantity being measured".
Comment In general, for a given set of information, it is understood that the measurement uncertainty is associated with a stated quantity value. A modification of this value results in a modification of the associated uncertainty.
Comment Metrological uncertainty includes components arising from systematic effects, such as components associated with corrections and the assigned quantity values of measurement standards, as well as the definitional uncertainty. Sometimes estimated systematic effects are not corrected for but, instead, associated measurement uncertainty components are incorporated.
Altlabel A metrological uncertainty can be assigned to any objective property via the 'hasMetrologicalUncertainty' relation.

Comment In the same system of quantities, dim ρB = ML−3 is the quantity dimension of mass concentration of component B, and ML−3 is also the quantity dimension of mass density, ρ.
ISO 80000-1
Comment Measured or simulated 'physical propertiy'-s are always defined by a physical law, connected to a physical entity through a model perspective and measurement is done according to the same model.

Systems of units suggests that this is the correct approach, since except for the fundamental units (length, time, charge) every other unit is derived by mathematical relations between these fundamental units, implying a physical laws or definitions.
Comment Measurement units of quantities of the same quantity dimension may be designated by the same name and symbol even when the quantities are not of the same kind.

For example, joule per kelvin and J/K are respectively the name and symbol of both a measurement unit of heat capacity and a measurement unit of entropy, which are generally not considered to be quantities of the same kind.

However, in some cases special measurement unit names are restricted to be used with quantities of specific kind only.

For example, the measurement unit ‘second to the power minus one’ (1/s) is called hertz (Hz) when used for frequencies and becquerel (Bq) when used for activities of radionuclides.

As another example, the joule (J) is used as a unit of energy, but never as a unit of moment of force, i.e. the newton metre (N · m).

— quantities of different quantity dimensions are always of different kinds, and
— quantities having the same quantity dimension are not necessarily of the same kind.

Comment A quantity value is not necessarily a property, since it is possible to write "10 kg", without assigning this quantity to a specific object.
Comment Following the International Vocabulary of Metrology (VIM), EMMO distinguishes between a quantity (a property) and the quantity value (a numerical and a reference).

So, for the EMMO the symbol "kg" is not a physical quantity but simply a 'Symbolic' object categorized as a 'MeasurementUnit'.

While the string "1 kg" is a 'QuantityValue'.

Comment A solid is defined as a portion of matter that is in a condensed state characterised by resistance to deformation and volume changes.
Comment In manufacturing, a workpiece is a single, delimited part of largely solid material that is processed in some form (e.g. stone ).
Comment In physics, a rigid body (also known as a rigid object[2]) is a solid body in which deformation is zero or so small it can be neglected. The distance between any two given points on a rigid body remains constant in time regardless of external forces or moments exerted on it. A rigid body is usually considered as a continuous distribution of mass.

Comment "In the name “amount of substance”, the word “substance” will typically be replaced by words to specify the substance concerned in any particular application, for example “amount of hydrogen chloride, HCl”, or “amount of benzene, C6H6 ”. It is important to give a precise definition of the entity involved (as emphasized in the definition of the mole); this should preferably be done by specifying the molecular chemical formula of the material involved. Although the word “amount” has a more general dictionary definition, the abbreviation of the full name “amount of substance” to “amount” may be used for brevity."

Comment In physics, a partition function describes the statistical properties of a system in thermodynamic equilibrium. Partition functions are functions of the thermodynamic state variables, such as the temperature and volume. Most of the aggregate thermodynamic variables of the system, such as the total energy, free energy, entropy, and pressure, can be expressed in terms of the partition function or its derivatives. The partition function is dimensionless.
