Classification - (or class) - an unquantifyable property that has descriptive divisions called types.
Classifications can also be subdivided into subclassification types, so that, a
description can be both a type and a classification. See property overview for other aspects of object or
system description.
- (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'..
- (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.
- "... everything after its kind" - Genesis
- For example, an object can be classified as organic or inorganic.
Organic objects can be subdivided into animal, plant, microorganism, genus, phylum etc..
Trees, vines etc. are types of plants. Ash, oak, and poplar etc. are types which subdivide
the tree classification category.
- Usage: 'The tree(classification) is oak (type)', but also 'The
plant (classification) is a tree (type)'.
