Property - A distinguishable characteristic of an object or substance used for evaluation, comparison, grouping or demarcation purposes. A property maybe numerically quantitative (quantity having values) or be a classification from an unquantifable taxonomy requiring literals (words) with descriptive subgroupings (types) for demarcation. See property overview for expanded understanding of relation to other words.

Examples-

• Quantity - The mass of an object is quantifiable and can be written as a numerical value with units such as 10 kilograms. Acceleration is also quantifiable (given the reference coordinate system) and may have a value of 9.8 meters per second squared.

• Classification (subjective) - Typically, color is an unquantifiable classification having types (groupings) such as blue, green, or mauve and can be subjective. Color can be nominally quantitative with a red-green-blue or yellow-magenta-cyan numerical values. Note: dye lots vary with the same nominal values. Useage: 'The surface is blue' or 'the surface has a blue color property' or even more specific 'the surface has a blue type for the color classification property'..

• Classification (distinct) -
  • Machine tools can be classified according to the arrangement of their carriages. An XYFZ type machine has a structural loop that goes from the X carriage (table) to the Y carriage (saddle) to the frame to the Z carriage (with spindle and tool).
  • Biological lifeforms are classified, categorized, and grouped (typed) according to unquantifiable genera, species, phyla, classes, and orders. These groupings are not subjective but mostly distinct. Also, the human genome (DNA sequence) provides an extensive taxonomy for describing individuals.
