Property

We know real world entities through observation/perception. A non-perceivable real world entity does not exist (or it exists on a plane of existance that has no intersection with us and we can say nothing about it). Perception/observation of a real wolrd entity occurs when the entity stimulate an observer in a peculiar way through a well defined perception channel. For this reason each property is related to a specific observation process which involves a specific observer with its own perception mechanisms. The observation process (e.g. a look, a photo shot, a measurement) is performed by an observer (e.g. you, a camera, an instrument) through a specific perception mechanism (e.g. retina impression, CMOS excitation, piezoelectric sensor activation) and involves an observed entity. An observation is a semiotic process, since it stimulate an interpretant within the interpreter who can communicate the perception result to other interpreters through a sign which is the property. Property subclasses are specializations that depend on the type of observation processes. e.g. the property 'colour' is related to a process that involves emission or interaction of photon and an observer who can perceive electromagnetic radiation in the visible frequency range. Properties usually relies on symbolic systems (e.g. for colour it can be palette or RGB). Hardness is a subclass of properties. Vickers hardness is a subclass of hardness that involves the procedures and instruments defined by the standard hardness test. A 'Property' is a sort of name or label that we put upon objects that interact with an observer in the same specific way. e.g. "hot" objects are objects that interact with an observer through a perception mechanism aimed to perceive an heat source. Let's define the class 'colour' as the subclass of the properties that involve photon emission and an electromagnetic radiation sensible observer. An individual C of this class 'colour' can be defined be declaring the process individual (e.g. daylight illumination) and the observer (e.g. my eyes) Stating that an entity E hasProperty C, we mean that it can be observed by such setup of process + observer (i.e. observed by my eyes under daylight). This definition can be generalized by using a generic human eye, so that the observer can be a generic human. This can be used in material characterization, to define exactly the type of measurement done, including the instrument type. A 'Perceptual' referring to a specific code that is used as 'Conventional' sign to represent an 'Object' according to a specific interaction mechanism by an 'Observer'. (A property is always a partial representation of an 'Object' since it reflects the 'Object' capability to be part of a specific 'Observation' process)
