Description

Abstract Concept
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 (Aggregate Member) - ) external Building Blocks within the Aggregate Block.

Structural Partition of Aggregate Block: an Aggregate Block is either an Ordering Connection or an Aggregate Entity Block

Functional Domain: Compositionality

The purpose of the Compositionality family of concepts is to provide syntactic mechanisms that support the construction of composite Building Blocks.

Relationship Table

Relationship	Cardinality	Target Entity	Source Entity	Description
Hierarchical Member	[*..0]	Building Block	Aggregate Block	A Hierarchical Member is an Aggregate Member that is also a Block Lexical Scope for the Building Block it aggregates: it relates its aggregated block by nesting (see Scoped Building Block).Hierarchical Members are used to build hierarchical structures of Building Blocks, in constrast to Block Members which are used to build network structures of Building Blocks.Hierarchical Members are the KerML equivalent of composite features.
Block Member	[*..0]	Building Block	Aggregate Block	A Block Member is an Aggregate Member that aggregates its releated Building Block by reference (see Reference Relation).Block Members are used to build network structures of Building Blocks while Hierarchical Members are used to build hierarchical structures of Building Blocks.
Aggregate Member	[*..0]	Building Block	Aggregate Block	Abstract Relationship An Aggregate Member is an Entity that serves as an internal constituent of an Aggregate Block, incorporating (aggregating) an external Building Block into its parent structure.Aggregation is the syntactic mechanism that enables the construction of modular, composite Building Blocks. It establishes a reified Relation (the nested Aggregate Member) between the Aggregate Block and the aggregated Building Block, allowing the definition of local characteristic specific to the Aggregate Member. This mechanism facilitates the expression of emergent properties within the composite structure of the Aggregate Block .Examples:. Attributes of a UML class are Aggregate Members.. Steps of a process are Aggregate Members.
Nesting Relation	[*..0]	Entity	Lexical Scope	Abstract Relationship A Nesting Relation is a Relation that references its target Entity by nesting, using a Nesting Adjacency.Nesting is a fundamental concept in complex systems organization where elements are contained within other elements, creating hierarchical or constextual web-like structures. This embedding mechanism intrinsically links the properties, behaviors, and lifecycles of nested entities to their containing entities, forming cohesive units at multiple scales.Nesting facilitates the emergence of complex Aggregate Blocks and properties from simpler entities, enables efficient design of systems across levels, and supports both autonomy and integration within systems (see Compositionality).Nesting also facilitates the creation of modules through packaging of Building Blocks (see Packaging).
Typology	[*..0]	Class of Entity	Entity	Abstract Relationship A Typology is a Relation between an Entity and its categorical nature - the intrinsic properties or criteria that determine the Entity membership within a Class of Entity. Typology governs two distinct categorization mechanisms:- instance of Entity: assigning a Ordered Entity to a predefined Class of Entity based on shared characteristics (e.g., grouping by common traits).- SubTypeOfEntity: refining a Class of Entity into a subclass with narrower criteria (e.g., inheritance hierarchies or subtype relationships).While instance of Entity focuses on grouping Ordered Entitys into Class of Entitys, SubTypeOfEntity emphasizes hierarchical refinement of Class of Entityes themselves. Both mechanisms operate under the umbrella of typology, which formalizes how Ordered Entitys are systematically categorized.
Reference Relation	[*..0]	Entity	Entity	Abstract Relationship A Reference Relation is a Relation that points at a target Entity which is not in the Lexical Scope of its source Entity.
Existential Dependency	[1..1]	Entity	Entity	Abstract Relationship An Existential Dependency relationship is a Relation where the source Entitys existence depends on the existence of the target Entity.The cardinality of the set of targetted Entity is [1..1].
Existential Independence	[*..0]	Entity	Entity	Abstract Relationship An Existential Independence relation is a Relation that specifies that the existence of the source Entity doesnt depend on the existence of its target Entity.The cardinality of set of targetted Entity is [0..*].
instance of Entity	[*..0]	Class of Entity	Entity	Abstract Relationship instance of Entity is a Typology relationship that relates an Entity to a Class of Entity, as instance of this Class of Entity.
