NameDescription
4D Composite Knowledge Graph
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.
Compositionality
The purpose of the  Compositionality family of concepts is to provide syntactic mechanisms that support the construction of composite  Building Blocks.
The  Compositionality pattern handles situations where  Building Blocks have an internal structure. Such  Building Blocks are called Aggregate Blocks. They are made of internal nested Entitys called  Aggregate Members.  Aggregate Members contextualizes  Building Blocks living outside the Aggregate Block structure (specialization in  OMG - Kernel Modeling Language (KerML) is such an  Aggregate Member).
Advanced Aggregate Block features are provided by  Bounded Aggregates which hide their internal structure to the outside world by means of a formal boundary (see  Ordering Connection).
Legend
Packaging
The  Packaging domain defines the core elements of  Building Block and  Container which provide the basis for building modules.
 Building Blocks are reusable units They have an independent existence. Thereby, they cannot be nested in other structures which would hide their existence (lexical scope). Because of their independent existence, they must be owned by an independent artifact which sole purpose is model management  Containers .  Containers are dedicated to model management:
. They own blocks to which they provide existence.
. They can provide namespace to blocks.
. They have dependencies on other  Containers which blocks have relationships to blocks they packaged.
Reflexive Knowledge Graph
The  Reflexive Knowledge Graph domain defines the top level constructs of Entitys,  Relationships, their multi-level classification and composition.
It forms the second layer of  SysFEAT's graph architecture. In this domain,  Relationships are refied as first class  Elements, allowing them to be further described and qualified.
Multi-level classification is implemented by  PowerTyping, which enables open and flexible meta-modeling capabilities, This includes support for reflexive meta-modeling,  for example allowing  Meta-Class to be an instance of itself.
Powertyping also applies to relationships, including the  Composition (Whole/Part) relationship.
This design grounds the  Reflexive Knowledge Graph in non-well-founded set theory, ensuring consistency in circular and self-referential structures (see associated external references).
The  4D Composite Knowledge Graph provides additional structuring of Entitys and  Relationships by implementing the  Compositionality pattern which establishes the concepts of dynamic locality and connections.
Upper Ontology
The  Upper Ontology domain encompasses five fundamental domains that establish the foundation for the modeling syntax and semantic.
1) The  Elementary Graph defines basic constructs for relating and classifying elements in a directed graph.
2) The Reflexive Knowledge Graph defines the elementary constructs of Entity,  Relationship and their multi-level classification. Its provides the foundation for open meta-modeling.
3)  Packaging, as aspect of modularity, defines syntactic constructs used to group reusable entities ( Building Blocks) into modules called  Containers.
4)  Compositionality, another aspect of modularity, defines the syntactic constructs used to build Entitys that have an internal structure and boundaries.
5) The  4D Composite Knowledge Graph defines Bounded Individuals (entities that exists over space and time) how they are composed (mereology), qualified (properties) and connected, enabling effective representation of meaning.

NameDescription
A
 Abstract Entity
 Abstract Entity is a class of Entitys that cannot have direct instances and represent aspects of entities.
It is the power instance of  Orderless Class, which means that its sub-types can belong to any  Ordered Class.
Example:
1) Aspects of Entitys, such as  Lexical Scope.
  Aggregate Block An  Aggregate Block is a  Building Block which has an internal structure made of  Aggregate Members which, through nesting ( Membership of -Aggregate Member-), contextualizes/aggregates ( Aggregation of -Building Block- ) external  Building Blocks within the  Aggregate Block.
 Aggregate Entity Block
An  Aggregate Entity Block is a self-contained and independant Aggregate Block that is not a  Ordering Connection.
Examples:
- Operating Eco-System;
-  Action Process;
-  Directive;
B
 Block Collection
A  Block Collection is an Entity  that is a set of  Building Blocks.
The grouping of   Building Blocks can be achieved either by reference ( Referencing Relationship) or by nesting ( Nesting Relationship), in which case the  Block Collection serves as a Lexical Scope.
Example:
-  Container Package as a  Block Lexical Scope.
-  Asset Portfolio as a pure  Block Collection.
 Block Lexical Scope
A  Block Lexical Scope is a  Block Collection that is also a  Lexical Scope for the  Building Blocks it groups.
A  Block Lexical Scope defines the existence of its grouped  Building Blocks through nesting.
 Bounded Aggregate
A  Bounded Aggregate is an  Aggregate Entity Block which hides its internal structure to the outside world by means of formal Borders.
The only way to access a  Bounded Aggregate is through its formal Borders, which ensures the aggregate's internal consistency.
The Borders of a  Bounded Aggregate is determined by the  Ordering Connections it can participate to.
Within a  Bounded Aggregate structure,  Bounded Members can be linked together through  Ordering Connectors.
The nature of  Ordering Connectors is given by their associated  Ordering Connection.
Examples:
-  Action Processes are bounded by their start and end events (see  Behavioral Event).
-  Applications are bounded by their APIs borders ( API Service Point and  API Request Point).
  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.
 Building Block
A  Building Block is an autonomous Entity that contributes to the makeup of other  Building Blocks.
 Building Blocks can be either reusable entities (packaged in  Containers) or be local to the Aggregate Block that references them (see  Block Lexical Scope and  Hierarchical Member).
Examples:
-  Functionality(ies),  Business Process(es),  Data Entity(ies), Tags, ARE  Building Blocks.
-  Process Steps or  Attributes of a data entity ARE NOT  Building Blocks. They are members on an internal structure (see  Aggregate Member).
C
 Category 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 Entity
A  Class of Entity is a  Class of Element that classifies Entitys. Being a subtype of Entity, it is also an instance of itself.
Note:
1)   SysFEAT is a higher-order ontology, so   Class of Entity may have members that are also  Class of Entity (Class of Classes).
2)   SysFEAT is also a non-well-founded allows for self-referencing   Class of Entity.
 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
 Class Partition
  Concrete Entity
 Concrete Entity is a class whose instances are classifed by an  Ordered Class: it is the power instance of  Ordered Class.
Examples:
-
 Container
A  Container is a collection of  Building Blocks whose existence and meaning are defined by the  Container.
A  Container is both:
1. A Lexical Scope: the meaning and usage of a  Building Block is only applicable within the context of the  Container to which it belongs.
2. A universe of discourse: the complete range of  Building Blocks that are expressed, assumed, or implied in an architecture domain.
Examples:
-  Container Package
- Library
- Enterprise
 Container Package
A  Container Package is a  Container which sole purpose is model management.
Examples:   Library, Information Dictionary
Conterexamples: Enterprises or Infrastructure Landscapes are  Containers but are not  Container Packages because they have functional purposes that go beyond model management.
E
 Elementary Block An  Elementary Block is a  Building Block which doesn't have an internal structure.
  Entity
An  Entity is a distinct, identifiable  Element that has a proper existence (living or non living). It is accessible by some referencing mechanism and can establish elementary relationships ( Relationship) to other  Entitys.
 Entity is the powerinstance of Class of Entity: all subtypes of  Entity are instances of Class of Entity.
F
 Family of Class
 First Order Class
 First Order Class is defined as the  Meta-Class of all subclasses of Particular Entity.
Each instance of  First Order Class is a Class of Entity, each of whose instances is necessarily an Particular Entity.
I
  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).

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.

. Oackland digital hospital after its renovation (2022 - ...).
L
 Lexical Scope
A  Lexical Scope is a kind of  Abstract Entity that defines the existence, visibility, and accessibility of the entities nested within it through a  Nesting Relationship.
Nested Entitys have no independent identity or validity outside the lexical or structural scope in which they are defined - they exist only within and for the duration of their parent construct.
Every Entity belongs to exactly one  Lexical Scope.
A  Lexical Scope carries no intrinsic semantic meaning; it serves purely as a syntactic mechanism for establishing hierarchical containment.
Examples:
1) Composite structures nesting their internal constituents.
2) Social structures nesting their roles and functions.
3) Computer functions nesting their local variables or inner functions
4) Packages nesting their building blocks.
M
 Meta Family of Class
A  Meta Family of Class is a  Class of Classes of Element (its members are themselves  Class of Elements), typically used to group or organize collections of  Class of Elements that share some structural, relational, or definitional property.
In contrast to families of sets, which are sets of sets, a family of classes operates at a higher ontological level-its elements may represent universes, types, or conceptual groupings rather than individual sets.
 Meta-Class
 Meta-Class (also called  Class of Classes of Entity) is defined as the Class of Entity of all Class of Entitys each of whose instances is necessarily a Class of Entity.
In other word,  Meta-Class is the powertype of Class of Entity: all sub-classes of Class of Entitys are instances of  Meta-Class.
Since  Meta-Class is itself a sub-type of Class of Entity,  Meta-Class is an instance of itself.
 Meta-Class Partition
O
 Ordering Connection
An  Ordering Connection is an Aggregate Block that defines possible connections between the Borders of two or more  Bounded Aggregates.
Examples:
-   Outcome Event.
-  Service Interface.
  Orderless Class An  Orderless Class is a Class of Entity which instances can belong to different meta-modeling order. This includes Class of Entitys that are instances of themselves, such as .
 Orderless Meta-Class
 Orderless Meta-Class is the  Meta-Class of Orderless Class.
All its instance are Class of Entitys that can belong to multiple level of powertyping, an allows some of the classes to be member of themselves.
P
  Particular Entity
A  Particular Entity is a Concrete Entity that is not itself a class (Class of Entity): it cannot have instances. The " Particular Entity" class is the powerinstance of  First Order Class. 
 Particular Entitys are the most common type of entities.
Examples:
. The set of numbers {1,2,3,4}.
. The mathematical constant π (pi).
. The English word "Tree" (as a specific string of characters in a specific language).
. The Eiffel tower (31st March 1889 - ...).
. Mount Vesuvius eruption (Aug. 24-25, A.D. 79).
 Power Class A  Power Class of a class A—denoted as P*(A)—is the class whose members are every possible subclass of A, including A itself and the empty class.
  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
S
 Second Order Class
 Second Order Class is defined as the  Meta-Class of all subclasses of  First Order Class.
Each instance of  Second Order Class is a class, each of whose instances is a  First Order Class.
 First Order Class is an instance of  Second Order Class since, by definition, all of its instances are  First Order Classes.
Examples:
1) Car-Brand (with instances such as VolkswagenCar and HondaCar),
2) AnimalSpecies (with instancessuch as GreyWolf and Dodo), Occupation, and USArmyRank.
 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.
T
  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)

Exemples:
- Birth,
- Death,
- Start of the plinian phase of a volcanic eruption.
- Hospital opening.
U
 Unbounded Aggregate
An  Unbounded Aggregate is an  Aggregate Entity Block that does not have boundaries and, thereby, that cannot participate to  Ordering Connections.
Examples:
-  Operating Eco-System;

. 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
