comment: "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 height of silver cup 232
-The RGB value matrix of my digital image IMG_0025 from 4-5-2007
- the wingspan of my stuffed chaffinch ‘Fringilla coelebs Linnaeus, 1758’
-the calibrated C14 date of bone splinter AC-1983-04532
-The number of coins in the silver hoard XXXX" (string)
