papers/003 — Architecture as an Abstract Object
Status: Research Draft
Version: 0.1
Abstract
Previous papers introduced the primitive entities of Derivable Architectures and proposed the existence of architectural identity.
This paper investigates a more fundamental question:
What kind of object is an architecture?
The objective is not to characterize specific architectures but to determine the level of abstraction at which architectures exist.
1. Motivation
Engineering literature frequently describes architectures through documents, diagrams or implementations.
However, observations obtained from the Institutional Continuity Architecture suggest that none of these constitute the architecture itself.
Instead, they appear to represent the architecture.
This distinction motivates the present investigation.
2. Observation
The ICA Baseline remained architecturally stable despite repeated editorial revisions.
Likewise, multiple implementation profiles were produced without altering the constitutional architecture.
These observations suggest that architecture exists independently of its representations.
3. Representation versus Object
The following distinction is proposed.
An architecture is not:
- a document;
- a diagram;
- a software repository;
- a legal statute;
- a database.
These are representations.
The architecture is the abstract object represented by them.
4. Architectural Persistence
Representations may change.
Artifacts may change.
Instances may change.
An architecture persists provided its architectural identity is preserved.
Persistence therefore belongs to the architecture rather than to its representations.
5. Architectural Objects
An architecture is proposed to be an abstract object possessing:
- identity;
- admissible operations;
- invariants;
- histories;
- representations.
None of these individually constitutes the architecture.
Together they characterize its observable behavior.
6. Consequences
Treating architectures as abstract objects immediately explains several observations.
Different representations may describe the same architecture.
Multiple artifacts may realize the same architecture.
An architecture may survive complete replacement of its artifacts.
Architectural evolution becomes conceptually distinct from artifact evolution.
7. Conjecture
Architectures constitute a distinct class of abstract objects whose defining characteristic is the existence of identity-preserving derivation.
This conjecture remains unproven.
8. Open Questions
Can architectures exist without representations?
Can two architectures possess identical representations?
Can architectural objects be composed?
Can architectures themselves be derived?
These questions motivate subsequent papers.
Status
This paper proposes a conceptual interpretation of architectures motivated by observations from the ICA.
Whether architectures form a mathematically distinct class of abstract objects remains an open research question.
