CONCEPT DOMAIN - 4D Composite Knowledge Graph
| Description | The purpose of the 4D Composite Knowledge Graph is to layer structured spatio-temporal concepts onto the Reflexive Knowledge Graph, The 4D Composite Knowledge Graph integrates the capabilities of Reflexive Knowledge Graphs (entities, relationships, Composition (Whole/Part) and multi-level Classification) whith those of Compositionality (composite structures) resulting in the addition of the following key features: 1) Mereological Aggregate Composition relationships, providing dynamic locality to composition.. 2) Individual-Property distinction: a clear ontological separation between Bounded Individuals (entities that exist in space and time) and their properties (Property). A dedicated Typology characterizes how individuals relate to and instantiate these properties. 3) Temporal Framing: the introduction of temporal connections (Temporal Bounding) that define the temporal boundaries of Bounded Individuals, enabling the explicit modeling of state changes, events, and persistence over time. |

Bounded Individual |
Bounded Individuals are Individuals which have a life cycle, bounded by Temporal Boundings. Because of its composite nature, Bounded Individual is a sub-type of Bounded Aggregate. Bounded Individuals shall be made distinct from Class of Bounded Individual which they are instance of. Bounded Individuals are represented with light orange boxes (see the Meta-Model Legend). Examples: . The Eiffel tower (31st March 1889 - ...). . William Shakespeare in its Early Theatrical Career (1592-1600). . Confucius (685-758). . Mount Vesuvius eruption (Aug. 24-25, A.D. 79). . Oackland digital hospital after its renovation (2022 - ...) . The execution of the registration process at the Oackland digital hospital, by John Smith, on 17 March 2020.

A Category is a used to classify Class of Bounded Individual. |
Class of Bounded Individual |
A Class of Bounded Individual is a Class of Individual which denotes Bounded Individuals that have a proper life cycle, bounded by Temporal Bounding Types. Class of Bounded Individual is the powertype of Bounded Individual. It means that all sub-types of Bounded Individual are instances of Class of Bounded Individual. Examples: - Car, , Application, - A Process Type (Action Process) such as the registration process used at the Oackland digital hospital during the COVID-19 pandemic. Counterexamples: - Project is not a Class of Bounded Individual because its instances have a spatio-temporal extent. Project is a subtype of Bounded Individual. - Capability is not a Class of Bounded Individual. It is a Class of Property.

Class of Class of Bounded Individual |
A Class of Class of Bounded Individual is a Class of Class of Individual which is the powertype of Class of Bounded Individual . It means that all sub-types of Class of Bounded Individual are instances of Class of Class of Bounded Individual. |
|
Class of Class of Individual |
A Class of Class of Individual is a that classifies Class of Individuals. Class of Class of Individual is the powertype of Class of Individual. Example: - Property Types such as Temperatures or colors.
|
|
Class of Individual |
A Class of Individual is a First Order Class of Entitys that exist in space and time. It is the powertype of Individual. Class of Individuals are represented as dark orange boxes (see the Meta-Model Legend) . Examples: - Red; - 12 kg; - Top Secret (TS) confidentiality. - Birth, - Death,
|
Class of Property |
A Class of Property is an abstract Class of Individual, which purpose is to qualify Bounded Individuals and their classes (Class of Bounded Individual). Because instances of Class of Property are Propertys, they do not have proper instances: there are no instances of "red", but there are red Bounded Individuals. Example: - 10 degree celcius; - Ability to cook (a capability); - Red; - 12 kg; - Top Secret (TS) confidentiality. - 7/7 availability

Individual |
Individuals are Entitys which represent things that exist over space and time. Individuals are represented as light orange boxes, while there classes are represented as dark orange boxes (see the Meta-Model Legend) . Examples: . The Eiffel tower completion (31st March 1889) . The Eiffel tower (31st March 1889 - ...). . William Shakespeare birth (1592) . William Shakespeare in its Early Theatrical Career (1592-1600). . Confucius (685-758). . Confucius death (758). . Mount Vesuvius eruption (Aug. 24-25, A.D. 79). . Oackland digital hospital after its renovation (2022 - ...) . The execution of the registration process at the Oackland digital hospital, by John Smith, on 17 March 2020.

Individual State |
An Individual State is a temporal slice of a Bounded Individual. Examples: . The state of the Eiffel tower during the 1900 World Fair, with its improved elevators and electric illuminations (Apr 14, 1900 - Nov 12, 1900). . William Shakespeare in its early theatrical career (1592-1600). . Confucius in its early childhood. . The first Plinian phase of the Mount Vesuvius eruption (18 to 20 hour, Aug. 24 A.D. 79), that projected a column of volcanic debris and hot gases. . Oackland digital hospital after its renovation (2022 - ...).

Property |
Property is the power instance of Class of Property. All its subtypes are instances of Class of Property such as: - 10 degree celcius; - Ability to cook (a capability); - Red; - 12 kg; - Top Secret (TS) confidentiality. - 7/7 availability |
Property Type |
A Property Type is a Class of Class of Individual Object that is used to classify Propertys. Example: - Temperature - Color - Weight - Confidentiality - Availability
|
State Class |
A State Class is a class of the temporal slices of a Class of Bounded Individual. It is the powertype of Individual State. Examples: . The lifecyle phases of buildings such as a skycraper: construction phase, operation and maintenance phase, decommissioning phase. . The lifecycle phases of a person, such as childhood, adulthood, eldery stage. . The phases of a volcanic eruption: magma accumulation, plinian phase, eruptive phase, effusive phase, declining phase. . The lifecyle phases of a hospital such as construction phase, operation and maintenance phase, renovation and expansion phase, decommissioning phase.
|
Temporal Bounding |
A Temporal Bounding is an Individual whose temporal extent is instantaneous, and whose spatial extent corresponds with the start or end of the Bounded Individuals for which it is the temporal border. Example: . The Eiffel tower completion (31st March 1889) . William Shakespeare birth (1592) . Confucius death (758). . Start of the first Plinian phase of the Mount Vesuvius eruption (18h, Aug. 24 A.D. 79) . Oakland hospital opening in 1994. |
Temporal Bounding Type |
A Temporal Bounding Type is Class of Individual that defines the type of temporal boundaries that delimitate Class of Bounded Individuals. It is a class of Temporal Bounding. Exemples: - Birth, - Death, - Start of the plinian phase of a volcanic eruption. - Hospital opening. |
|
Whole Life Class |
Whole Life Class is the power-type of Whole Life Individual. Examples: . A type of building such as a skycraper. . A type of person such as a philosopher. . A type of activity such as a volcanic eruption. . A type of facility such as a Hospital. . A Process Type (Action Process) such as the registration process used at the Oackland digital hospital during the COVID-19 pandemic. |
|
Whole Life Individual |
A Whole Life Individual is a Bounded Individual that is not the temporal slice of any other Bounded Individual. A Whole Life Individual includes its past and future. Examples: . The Eiffel tower (31st March 1889 - ...). . William Shakespeare (23 April 1564 - 23 April 1616). . Confucius (685-758). . Mount Vesuvius eruption (Aug. 24-25, A.D. 79). . Oackland digital hospital (1994 - ...). . The execution of the registration process at the Oackland digital hospital, by John Smith, on 17 March 2020.
