Interoperability in intelligent systems can be analytically decomposed into three independent layers:
- Syntactic Interoperability
- Semantic Interoperability
- Operative Interoperability
These layers are analytical distinctions.
They are not maturity stages.
They are not technical protocols.
They are not compliance requirements.
Definition:
The ability of independent actors to exchange data reliably.
Focus:
- connectivity
- transmission reliability
- data integrity
- availability
Diagnostic Questions:
- Is connectivity stable?
- Is data complete?
- Is integrity ensured?
Failure Mode:
Communication breakdown or corrupted transmission.
Definition:
The ability of independent actors to interpret exchanged information consistently.
Focus:
- meaning alignment
- contextual consistency
- assumption synchronisation
- ambiguity resolution
Diagnostic Questions:
- Is interpretation consistent across actors?
- Are contextual assumptions aligned?
- Is ambiguity resolved?
Failure Mode:
Misinterpretation despite successful data exchange.
Definition:
The ability of autonomous actors to transform individual decision processes into structurally coherent collective action within a shared environment.
Focus:
- priority structuring
- decision arbitration
- conflict resolution
- behavioural alignment
- coordinated execution
Diagnostic Questions:
- How are conflicting decisions structurally resolved?
- How are priorities formally assigned or negotiated?
- How are autonomous decision processes aligned?
- How is collective execution stabilised?
Failure Mode:
Loss of coordinated collective action despite syntactic connectivity and semantic agreement.
Syntactic Interoperability does not imply Semantic Interoperability.
Semantic Interoperability does not imply Operative Interoperability.
Failure in any layer can compromise system-level interoperability.
Each layer must therefore be analysed independently.
The model:
- is not a standard
- is not a regulatory framework
- is not a protocol specification
- is not a maturity ladder
- is not a certification basis
It is strictly analytical.
