The Ontology

The ontology is a queryable canon of software architecture. It holds every principle with its relations and its repair, every term with its definition, every algorithm with its contract, the reasoning that derives them, the layers they live in and how every tension between them is resolved, and every reference from one record to another is a link.

Application Concerns

Every term in this category is listed as one record, with its kind, its definition and its aliases, the principles whose relations name it, the principle or contract that carries the same name where one exists, and the layer its category belongs to. A tag category also gives each term an example, which is the file the tag places or the rename from a refused word onto a covering tag.

Hidden Dependency

Details

Definition A dependency a component or an operation relies on without declaring it, so it surfaces only at runtime or when an unstated order is broken.

Referenced by Causal Dependency, Dependency Graph, Testability

Distinct from Test Pyramid Inversion: A hidden dependency is an undeclared requirement of a component or an operation, while test pyramid inversion is a suite weighted toward slow end-to-end tests.

Core Vocabulary

Every term in this category is listed as one record, with its kind, its definition and its aliases, the principles whose relations name it, the principle or contract that carries the same name where one exists, and the layer its category belongs to. A tag category also gives each term an example, which is the file the tag places or the rename from a refused word onto a covering tag.

Model Architecture

Every term in this category is listed as one record, with its kind, its definition and its aliases, the principles whose relations name it, the principle or contract that carries the same name where one exists, and the layer its category belongs to. A tag category also gives each term an example, which is the file the tag places or the rename from a refused word onto a covering tag.

Schema / Canonical Data / Semantics

Every term in this category is listed as one record, with its kind, its definition and its aliases, the principles whose relations name it, the principle or contract that carries the same name where one exists, and the layer its category belongs to. A tag category also gives each term an example, which is the file the tag places or the rename from a refused word onto a covering tag.

Details

Definition The requirement that names for the same concept be used consistently across an interface.

SOLID / Object-Oriented Design

Every term in this category is listed as one record, with its kind, its definition and its aliases, the principles whose relations name it, the principle or contract that carries the same name where one exists, and the layer its category belongs to. A tag category also gives each term an example, which is the file the tag places or the rename from a refused word onto a covering tag.

Contract Preservation

Details

Definition The requirement that a subtype honor every behavioral guarantee of the type it replaces.

Distinct from Invariant: Contract preservation binds a subtype to all of its base type's guarantees, while an invariant is one guarantee that holds in every state.

Distinct from Postconditions: Contract preservation binds a subtype to every guarantee, while a postcondition is the one an operation gives on return.

Distinct from Preconditions: Contract preservation binds a subtype to every guarantee, while a precondition is what an operation needs before it runs.

Structural Patterns

Every term in this category is listed as one record, with its kind, its definition and its aliases, the principles whose relations name it, the principle or contract that carries the same name where one exists, and the layer its category belongs to. A tag category also gives each term an example, which is the file the tag places or the rename from a refused word onto a covering tag.

How it is checked

Checked by ACID

Population The term's definition and every architecture edge that names the term

Freshness A verdict stands until the definition, the term's kind or an edge that names it changes

Refusal The resolution gate fails an edge that resolves to no term, and a definition that opens as another kind

Observation The resolution validator's pass over every edge target and every definition opening

Evidence Watched to fire and to accept: a suite plants a term no edge names, a dangling dependency and a second check home, and the bundled terms pass

Authoritative side The term record, which every edge that names the term cites

Depends on Not answered

Shape it refuses Not answered
