|
|
* Scope note: This class comprises quantifiable properties that can be measured by some calibrated means and can be
|
|||
|
|
* approximated by values, i.e. points or regions in a mathematical or conceptual space, such as natural or
|
|||
|
|
* real numbers, RGB values etc.
|
|||
|
|
*
|
|||
|
|
* An instance of E54 Dimension represents the true quantity, independent from its numerical
|
|||
|
|
* approximation, e.g. in inches or in cm. The properties of the class E54 Dimension allow for expressing
|
|||
|
|
* the numerical approximation of the values of an instance of E54 Dimension. If the true values belong
|
|||
|
|
* to a non-discrete space, such as spatial distances, it is recommended to record them as approximations
|
|||
|
|
* by intervals or regions of indeterminacy enclosing the assumed true values. For instance, a length of 5
|
|||
|
|
* cm may be recorded as 4.5-5.5 cm, according to the precision of the respective observation. Note, that
|
|||
|
|
* interoperability of values described in different units depends critically on the representation as value
|
|||
|
|
* regions.
|
|||
|
|
*
|
|||
|
|
* Numerical approximations in archaic instances of E58 Measurement Unit used in historical records
|
|||
|
|
* should be preserved. Equivalents corresponding to current knowledge should be recorded as additional
|
|||
|
|
* instances of E54 Dimension as appropriate.
|
|||
|
|
*
|
|||
|
|
* Examples:
|
|||
|
|
* - The 250 metric ton weight of the Luxor Obelisk
|
|||
|
|
* - The 5.17 m height of the statue of David by Michaelangelo
|
|||
|
|
* - The 530.2 carats of the Great Star of Africa diamond
|
|||
|
|
* - The AD1262-1312, 1303-1384 calibrated C14 date for the Shroud of Turin
|
|||
|
|
* - The 33 m diameter of the Stonehenge Sarcen Circle
|
|||
|
|
* - The 755.9 foot length of the sides of the Great Pyramid at Giza
|
|||
|
|
* - Christies’ hammer price for “Vase with Fifteen Sunflowers” (E97) has currency British Pounds (E98)
|
|||
|
|
*
|
|||
|
|
* In First Order Logic:
|
|||
|
|
* E54(x) ⊃ E1(x)
|
|||
|
|
*
|
|||
|
|
* Properties:
|
|||
|
|
* P90 has value: E60 Number
|
|||
|
|
* P91 has unit (is unit of): E58 Measurement Unit
