The word subjective applies to property intrisically subjective or non-well defined. In general, when an black-box-like procedure is used for the definition of the property.
This happens due to e.g. the complexity of the object, the lack of a underlying model for the representation of the object, the non-well specified meaning of the property symbols.
A 'SubjectiveProperty' cannot be used to univocally compare 'Object'-s.
e.g. you cannot evaluate the beauty of a person on objective basis.

The fact that there may be a finite granularity in the variations of the material basis (e.g. the smallest peak in a vynil that can be recognized by the piezo-electric transducer) does not prevent a data to be analog. It means only that the focus on such data encoding is on a scale that makes such variations negligible, making them practically a continuum.

The joule per mole (symbol: J· mol⁻¹) is an SI derived unit of energy per amount of material. Energy is measured in joules, and the amount of material is measured in moles. Physical quantities measured in J· mol⁻¹) usually describe quantities of energy transferred during phase transformations or chemical reactions. Division by the number of moles facilitates comparison between processes involving different quantities of material and between similar processes involving different types of materials. The meaning of such a quantity is always context-dependent and, particularly for chemical reactions, is dependent on the (possibly arbitrary) definition of a 'mole' for a particular process.

VIM defines a quantity as a "property of a phenomenon, body, or substance, where the property has a magnitude that can be expressed as a number and a reference".
A quantity in EMMO is a property and therefore only addresses the first part of the VIM definition (that is a property of a phenomenon, body, or substance). The second part (that it can be expressed as a number and a reference) is syntactic and addressed by emmo:QuantityValue.

The EMMO conceptualises the world using the primitive concepts of causality and parthood. Parthood is about the composition of world entities starting from other more fundamental entities. Causality is about the interactions between world entities.
The quantum is the smallest indivisible part of any world entity. Quantum individuals are the fundamental causal constituents of the universe, since it is implied that causality originates from quantum-to-quantum interactions. Quantums are no-dimensional, and their aggregation makes spacetime emerge from their causal structure. Causality between macro entities (i.e. entities made of more than one quantum) is explained as the sum of the causality relations between their quantum constituents.
The fundamental distinction between world entities is direct causality self-connectedness: a world entity can be self-connected xor not self-connected depending on the causality network of its fundamental components.
Void regions do not exist in the EMMO, or in other words there is no spacetime without entities, since space and time are measured quantities following a causality relation between entities (spacetime emerges as relational property not as a self-standing entity).
Entities are not placed in space or time: space and time are always relative between entities and are measured. In other words, space and time relations originates from causality interactions.
The disjoint union of the Item and Collection classes.
The class of all the OWL individuals declared by EMMO as standing for world entities.
EMMO entities dimensionality is related to their mereocausal structures. From the no-dimensional quantum entity, we introduce time dimension with the elementary concept, and the spacetime with the causal system concept.
The EMMO conceptualisation does not allow the existence of space without a temporal dimension, the latter coming from a causal relation between entities.
For this reason, the EMMO entities that are not quantum or elementaries, may be considered to be always spatiotemporal. The EMMO poses no constraints to the number of spatial dimensions for a causal system (except being higher than one).

An holistic perspective considers each part of the whole as equally important, without the need to position the parts within a hierarchy (in time or space). The interest is on the whole object and on its parts (how they contribute to the whole, i.e. their roles), without going further into specifying the spatial hierarchy or the temporal position of each part.
This class allows the picking of parts without necessarily going trough a rigid hierarchy of spatial compositions (e.g. body -> organ -> cell -> molecule) or temporal composition. This is inline with the transitive nature of parthood, as it is usually defined in literature.
The holistic perspective is not excluding the reductionistic perspective, on the contrary it can be considered its complement.
The union of classes whole and part.
A perspective characterized by the belief that some mereological parts of a whole (holistic parts) are intimately interconnected and explicable only by reference to the whole and vice versa.
A molecule of a body can have role in the body evolution, without caring if its part of a specific organ and without specifying the time interval in which this role occurred.
A product is a role that can be fulfilled by many objects, but always requires a process to which the product participates and from which it is generated.

A world entity is direct causally self-connected if any two parts that make up the whole are direct causally connected to each other. In the EMMO, topological connectivity is based on causality.
All physical objects, i.e. entities whose behaviour is explained by physics laws, are represented only by items. In other words, a physical object part is embedded in a direct causal graph that provides always a path between two of its parts.
Members of a collection lack such direct causality connection, i.e. they do not constitute a physical object.
Following graph theory concepts, the quantums of an item are all connected together within a network of causal relations, forming a connected causal graph. A collection is then a set of disconnected graphs.

Metrological uncertainty in EMMO is a slight generalisation of the VIM term 'measurement uncertainty', which is defined as "a non-negative parameter characterising the dispersion of the quantity being measured".
In general, for a given set of information, it is understood that the measurement uncertainty is associated with a stated quantity value. A modification of this value results in a modification of the associated uncertainty.
Metrological uncertainty includes components arising from systematic effects, such as components associated with corrections and the assigned quantity values of measurement standards, as well as the definitional uncertainty. Sometimes estimated systematic effects are not corrected for but, instead, associated measurement uncertainty components are incorporated.
A metrological uncertainty can be assigned to any objective property via the 'hasMetrologicalUncertainty' relation.

The entity (or agent, or observer, or cognitive entity) who connects 'Sign', 'Interpretant' and 'Object'.
For example, the ontologist may be interest in cataloguing in the EMMO how the same object (e.g. a cat) is addressed using different signs (e.g. cat, gatto, chat) by different interpreters (e.g. english, italian or french people).
The same applies for the results of measurements: the ontologist may be interest to represent in the EMMO how different measurement processes (i.e. semiosis) lead to different quantitative results (i.e. signs) according to different measurement devices (i.e. interpreters).
The interpreter is not the ontologist, being the ontologist acting outside the ontology at the meta-ontology level.
On the contrary, the interpreter is an agent recognized by the ontologist. The semiotic branch of the EMMO is the tool used by the ontologist to represent an interpreter's semiotic activity.

A causal object which is tessellated with only spatial direct parts.
e.g. the existent in my glass is declared at t = t_start as made of two direct parts: the ice and the water. It will continue to exists as state as long as the ice is completely melt at t = t_end. The new state will be completely made of water. Between t_start and t_end there is an exchange of molecules between the ice and the water, but this does not affect the existence of the two states.
If we partition the existent in my glass as ice surrounded by several molecules (we do not use the object water as direct part) then the appearance of a molecule coming from the ice will cause a state to end and another state to begin.
The definition of an arrangement implies that its spatial direct parts are not gained or lost during its temporal extension (they exist from the left to the right side of the time interval), so that the cardinality of spatial direct parts in an arrangement is constant.
This does not mean that there cannot be a change in the internal structure of the arrangement direct parts. It means only that this change must not affect the existence of the direct part itself.
The use of spatial direct parthood in state definition means that an arrangement cannot overlap in space another arrangement that is direct part of the same whole.

A quantity value is not necessarily a property, since it is possible to write "10 kg", without assigning this quantity to a specific object.
Following the International Vocabulary of Metrology (VIM), EMMO distinguishes between a quantity (a property) and the quantity value (a numerical and a reference).
So, for the EMMO the symbol "kg" is not a physical quantity but simply a 'Symbolic' object categorized as a 'MeasurementUnit'.

The class of individuals that stands for semiotic objects, i.e. objects that take part on a semiotic process.
Semiotic subclasse are defined using Peirce's semiotic theory.
"Namely, a sign is something, A, which brings something, B, its interpretant sign determined or created by it, into the same sort of correspondence with something, C, its object, as that in which itself stands to C." (Peirce 1902, NEM 4, 20–21).
The triadic elements:
- 'sign': the sign A (e.g. a name)
- 'interpretant': the sign B as the effects of the sign A on the interpreter (e.g. the mental concept of what a name means)
- 'object': the object C (e.g. the entity to which the sign A and B refer to)
This class includes also the 'interpeter' i.e. the entity that connects the 'sign' to the 'object'

A 'Perceptual' which stands for a real world object whose spatiotemporal pattern makes it identifiable by an observer as a sound.
When we use the term 'sound' what are we referring to? The EMMO identifis a sound as the physical object that can be heard by the observer (more exactly, by the sensor of the observer).
In this sense, a sound (which is an acoustical object) is to be identified as the air region that manifests the sound wave and is able to be perceived by an observer. In case the wave is travelling through water or steel, then these other media regions are the sounds.
If the waveform is travelling through a cable as electronic signal (analog or digital) it is no more a sound, since it cannot be perceived by an observer as an acoustical object. This electrical waveform (or digital packet) is another physical that may stand for a sound if interpreted by a device (e.g. an amplifier, a DA converter).
'acoustical' refers to the perception mechanism of the observer that can occur through a microphone, a ear.

The superproperty of the relations between a whole and its mereological parts that are still holistic wholes of the same type.
A volume of water has redundand parts other volumes of water. All this volumes have holistic parts some water molecules.
The purpose of this relation is to provide a parhood relation that does not go deep enough, in terms of decomposition, to break the holistic definition of the whole.
On the contrary, the holistic parthood, is expected to go that deep.

SI unit for force.
The "Newton" is the SI unit of force. A force of one newton will accelerate a mass of one kilogram at the rate of one meter per second per second. The newton is named for Isaac Newton (1642-1727), the British mathematician, physicist, and natural philosopher. He was the first person to understand clearly the relationship between force (F), mass (m), and acceleration (a) expressed by the formula F = m·a.

Manufacturing by separating particles of material from a solid body by non-mechanical means. Ablation refers both to the removal of layers of material and to the separation of workpiece parts. The production process of ablation is considered in its stationary instantaneous state, independently of the application of auxiliary processes necessary to initiate the process. Ablation is divided into three subgroups according to the order point of view (OGP) "process in the effective zone on the surface of the workpiece": - thermal ablation; - chemical ablation; - electrochemical ablation.

A fundamental physical process is made of one or more standard particles as input, and one or more standard particles as output, where each input is direct cause of each output.
Each fundamental physical phenomena refers to a Feynman diagram, hence is made at least of three standard model particles.
This requirement implies that a physical phenomena is either a decay, annihilation, interaction, collapse or creation phenomena (fundamental) or a composition of them (non-fundamental).
A causal system that is the representation of a Feynman diagram, where quantum represents the real particles entering and exiting the system.

A conventional that stands for an object according to a code of interpretation to which the interpreter refers.
A biography that makes use of a code that is provided by the meaning of the element of the language used by the author.
The name "red" that stands for the color of an object.
A conventional referring to an object according to a specific code that reflects the results of a specific interaction mechanism and is shared between other interpreters.
A coded is always a partial representation of an object since it reflects the object capability to be part of a specific determination.
A coded is a sort of name or label that we put upon objects that interact with an determiner in the same specific way.
For example, "hot" objects are objects that interact with an observer through a perception mechanism aimed to perceive an heat source. The code is made of terms such as "hot", "warm", "cold", that commonly refer to the perception of heat.
Let's define the class Colour as the subclass of the coded signs that involve photon emission and electromagnetic radiation sensible observers.
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 hasCoded 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 specialised for human eye perception, so that the observer can be a generic human, or to camera perception so that the observer can be a device.
This can be used in material characterization, to define exactly the type of measurement done, including the instrument type.

The EMMO conceptualises the world using the primitive concepts of causality and parthood. Parthood is about the composition of world entities starting from other more fundamental entities. Causality is about the interactions between world entities.
The quantum is the smallest indivisible part of any world entity. Quantum individuals are the fundamental causal constituents of the universe, since it is implied that causality originates from quantum-to-quantum interactions. Quantums are no-dimensional, and their aggregation makes spacetime emerge from their causal structure. Causality between macro entities (i.e. entities made of more than one quantum) is explained as the sum of the causality relations between their quantum constituents.
The fundamental distinction between world entities is direct causality self-connectedness: a world entity can be self-connected xor not self-connected depending on the causality network of its fundamental components.
Void regions do not exist in the EMMO, or in other words there is no spacetime without entities, since space and time are measured quantities following a causality relation between entities (spacetime emerges as relational property not as a self-standing entity).
Entities are not placed in space or time: space and time are always relative between entities and are measured. In other words, space and time relations originates from causality interactions.
While EMMO mereocausality conceptualisation can be used on any possibile domain, so that a quantum can be a Lego brick or an furniture component, it can be better understood when a quantum is elucidated as the smallest measured time interval of existence of an elementary particle (e.g. quark, photon).

In other words, a sequence of bit "1000010" in a RAM (a non-graphical entity) is a valid symbol since it can be decoded through ASCII rules as the letter "B". The same holds for an entity standing for the sound of a voice saying: "Hello", since it can be decomposed in discrete parts, each of them being associated to a letter of an alphabet.
A symbolic object possesses a reductionistic oriented structure.
For example, text is made of words, spaces and punctuations. Words are made of characters (i.e. atomic symbols).

A temporal relation between two entities occurs when the two entities are in a one directional causality relation. The idea is that a temporal relation always implies a one-directional causality between two entities, leading to a asymmetric relation.
This means that the causing entity can be in direct and optionally indirect causality relation with the effect entity. On the contrary, the effect entity cannot be in any causal relation (direct or indirect) with the causing entity.
A time contact occurs when x isDirectCause y and not(y isCauseOf x).
Each pair of entities in direct causality relation is either in hasNext or hasTwoWayCauseWith relation. The two are mutually exclusive.
This relation is asymmetric and irreflexive.

Measurement unit for Celsius temperature. This unit can only be used for expressing temperature differences.
Celsius, also known as centigrade, is a scale and unit of measurement for temperature. It can refer to a specific temperature on the Celsius scale as well as a unit to indicate a temperature interval, a difference between two temperatures or an uncertainty. This definition fixes the magnitude of both the degree Celsius and the kelvin as precisely 1 part in 273.16 (approximately 0.00366) of the difference between absolute zero and the triple point of water. Thus, it sets the magnitude of one degree Celsius and that of one kelvin as exactly the same. Additionally, it establishes the difference between the two scales' null points as being precisely 273.15 °C.

We say that an entity causes another if there is a quantum part of the first that is in causal relation with a quantum parts of the second.
An entity cannot cause itself (causal loops are forbidden) or a part of itself. For this reasons causality between entities excludes reflexivity and prevents them to overlap.
The relation between an individuals x and y, that holds if and only if:
a) y having a part that is causing an effect on a part of x
b) y and x non-overlapping
:isCauseOf owl:propertyDisjointWith :overlaps
Each pair of causally connected entities is either in isDirectCauseOf or isIndirectCauseOf relation. The two are mutually exclusive.
It applies to both quantums and macro-entities (entities made of more than one quantum). It is admissible for two entities to be one the cause of the other, excepts when they are both quantums.
The OWL 2 DL version of the EMMO introduces this object property as primitive causal relation. It refers to the macro causality relation mC(x,y), defined in the EMMO FOL version.
While the EMMO FOL introduces the quantum causality relation C(x,y) as primitive, the OWL 2 DL version substantially simplifies the theory, neglecting these lower level relations that are well above DL expressivity.

The candela per square metre (cd/m²) is the derived SI unit of luminance. The unit is based on the candela, the SI unit of luminous intensity, and the square metre, the SI unit of area. Nit (nt) is a deprecated non-SI name also used for this unit (1 nit = 1 cd/m²). As a measure of light emitted per unit area, this unit is frequently used to specify the brightness of a display device. Most consumer desktop liquid crystal displays have luminances of 200 to 300 cd/m²; the sRGB spec for monitors targets 80 cd/m2. HDTVs range from 450 to about 1000 cd/m2. Typically, calibrated monitors should have a brightness of 120 cd/m². Nit is believed to come from the Latin word nitere, to shine.

Thermal resistance is a heat property and a measure of a temperature difference by which an object or material resists a heat flow (heat per time unit or thermal resistance). Thermal resistance is the reciprocal thermal conductance. Absolute thermal resistance is the temperature difference across a structure when a unit of heat energy flows through it in unit time. It is the reciprocal of thermal conductance. The SI units of thermal resistance are kelvins per watt or the equivalent degrees Celsius per watt (the two are the same since as intervals).

The magnetic moment of a magnet is a quantity that determines the force that the magnet can exert on electric currents and the torque that a magnetic field will exert on it. A loop of electric current, a bar magnet, an electron, a molecule, and a planet all have magnetic moments. The unit for magnetic moment is not a base unit in the International System of Units (SI) and it can be represented in more than one way. For example, in the current loop definition, the area is measured in square meters and I is measured in amperes, so the magnetic moment is measured in ampere-square meters (A m2). In the equation for torque on a moment, the torque is measured in joules and the magnetic field in tesla, so the moment is measured in Joules per Tesla (J u00b7T-1). These two representations are equivalent: 1 A u00b7m2 = 1 J u00b7T-1.

A spatial contact between two entities occurs when the two entities are in an interaction relation whose causal structure is a representation of the fundamental interactions between elementary particles (Feynman diagrams).
It means that if two entities are in contact, then there is at least a couple of elementary particles, one part of the first and one part of the second, interacting according to one of the fundamental interactions through virtual particles. This kind of connection is space-like (i.e. interconnecting force carrier particle is offshelf).
Contacts between two entities exclude the possibility of other causal relations that are not included in a fundamental space-like interaction.
An interaction that is the sum of direct causality relations between two entities that are interpretable as fundamental physical interactions.
Spatial contact is symmetric and irreflexive.
The contact relation is not an ordering relation since is symmetric.

The interpretation of the term "matter" is not univocal. Several concepts are labelled with this term, depending on the field of science. The concept mass is sometimes related to the term "matter", even if the former refers to a physical quantity (precisely defined by modern physics) while the latter is a type that qualifies a physical entity.
It is possible to identify more than one concept that can be reasonably labelled with the term "matter". For example, it is possible to label as matter only the entities that are made up of atoms. Or more generally, we can be more fine-grained and call "matter" the entities that are made up of protons, neutrons or electrons, so that we can call matter also a neutron radiation or a cathode ray.
A more fundamental approach, that we embrace for the EMMO, considers matter as entities that are made of fermions (i.e. quarks and leptons). This would exclude particles like the W and Z bosons that possess some mass, but are not fermions.
Antimatter is a subclass of matter.
A physical object made of fermionic quantum parts.
A matter entity exclude the presence of (real) fundamental bosons parts. However, it implies the presence of virtual bosons that are responsible of the interactions between the (real) fundamental fermions.
Matter includes ordinary- and anti-matter. It is possible to have entities that are made of particle and anti-particles (e.g. mesons made of a quark and an anti-quark pair) so that it is possible to have entities that are somewhat heterogeneous with regards to this distinction.

`Ampere hour` is a practical unit of electric charge equal to the charge flowing in one hour through a conductor passing one ampere. An ampere-hour or amp-hour (symbol Ah, AHr, A · h, A h) is a unit of electric charge, with sub-units milliampere-hour (mAh) and milliampere second (mAs). One ampere-hour is equal to 3600 coulombs (ampere-seconds), the electric charge transferred by a steady current of one ampere for one hour. The ampere-hour is frequently used in measurements of electrochemical systems such as electroplating and electrical batteries. The commonly seen milliampere-hour (mAh or mA · h) is one-thousandth of an ampere-hour (3.6 coulombs).

An astronomical unit (abbreviated as AU, au, a.u., or ua) is a unit of length equal to 149,597,870,700 metres (92,955,807.273 mi) or approximately the mean Earth Sun distance. The symbol ua is recommended by the International Bureau of Weights and Measures, and the international standard ISO 80000, while au is recommended by the International Astronomical Union, and is more common in Anglosphere countries. In general, the International System of Units only uses capital letters for the symbols of units which are named after individual scientists, while au or a.u. can also mean atomic unit or even arbitrary unit. However, the use of AU to refer to the astronomical unit is widespread. The astronomical constant whose value is one astronomical unit is referred to as unit distance and is given the symbol A.

A WorkPiece is physical artifact, that has a proper shape and occupyes a proper volume intended for subsequent transformation. It is a condensed state, so it is a compact body that is processed or has to be processed.
A solid is defined as a portion of matter that is in a condensed state characterised by resistance to deformation and volume changes.
In manufacturing, a workpiece is a single, delimited part of largely solid material that is processed in some form (e.g. stone ).
In physics, a rigid body (also known as a rigid object[2]) is a solid body in which deformation is zero or so small it can be neglected. The distance between any two given points on a rigid body remains constant in time regardless of external forces or moments exerted on it. A rigid body is usually considered as a continuous distribution of mass.
It has a shape, so we conclude that it is solid

1.0
The union of the object or process classes.
The interest is on the 4D object as it extends in time (process) or as it persists in time (object):
- object (focus on spatial configuration)
- process (focus on temporal evolution)
The concepts of endurant and perdurant implicitly rely on the concept of instantaneous 3D snapshot of the world object, that in the EMMO is not allowed since everything extends in 4D and there are no abstract objects. Moreover, time is a measured property in the EMMO and not an objective characteristic of an object, and cannot be used as temporal index to identify endurant position in time.
For this reason an individual in the EMMO can always be classified both endurant and perdurant, due to its nature of 4D entity (e.g. an individual may belong both to the class of runners and the class of running process), and the distinction is purely semantic. In fact, the object/process distinction is simply a matter of convenience in a 4D approach since a temporal extension is always the case, and stationarity depends upon observer time scale. For this reason, the same individual (4D object) may play the role of a process or of an object class depending on the object to which it relates.
Nevertheless, it is useful to introduce categorizations that characterize persistency through continuant and occurrent concepts, even if not ontologically but only cognitively defined. This is also due to the fact that our language distinguish between nouns and verbs to address things, forcing the separation between things that happens and things that persist.
This perspective provides classes conceptually similar to the concepts of endurant and perdurant (a.k.a. continuant and occurrent). We claim that this distinction is motivated by our cognitive bias, and we do not commit to the fact that both these kinds of entity “do really exist”. For this reason, a whole instance can be both process and object, according to different cognitive approaches (see Wonderweb D17).
The distinction between endurant and perdurant as usually introduced in literature (see BFO SPAN/SNAP approach) is then no more ontological, but can still be expressed through the introduction of ad hoc primitive definitions that follow the interpreter endurantist or perdurantist attitude.

HUR

h
Measure of time defined as 3600 seconds.
The hour (common symbol: h or hr) is a unit of measurement of time. In modern usage, an hour comprises 60 minutes, or 3,600 seconds. It is approximately 1/24 of a mean solar day. An hour in the Universal Coordinated Time (UTC) time standard can include a negative or positive leap second, and may therefore have a duration of 3,599 or 3,601 seconds for adjustment purposes. Although it is not a standard defined by the International System of Units, the hour is a unit accepted for use with SI, represented by the symbol h.

A CausalSystem whose quantum parts are all bonded to the rest of the system.
It is natural to define entities made or more than one smaller parts according to some unity criteria. One of the most general one applicable to causal systems is to ask that all the quantum parts of the system are bonded to the rest.
In other words, causal convexity excludes all quantums that leave the system (no more interacting), or that are not yet part of it (not yet interacting).
So, a photon leaving a body is not part of the body as convex system, while a photon the is carrier of electromagnetic interaction between two molecular parts of the body, is part of the convex body.
