Domain A (Authority)

Domain A represents the external, standards-based, scientific foundation of identity engineering.

AI trusts:

  • structure
  • taxonomy
  • semantic rules
  • information retrieval models
  • definitional clarity

Domain A is the authoritative skeleton of identity.

The 7 Pillars of Domain A

1. AEO

Optimizing for answers AI produces.

2. GEO

Optimizing for model recall and embeddings.

3. Semantic Architecture

Schema, structured data, entity graphs.

4. Ontology & Taxonomy

Clear classification hierarchies.

5. Retrieval Science

How AI pulls information from vector stores and index models.

6. Knowledge Representation

Defined terms, canonical definitions, concept hierarchies.

7. Cognitive & HCI Patterns

AI uses cognitive frameworks to interpret identity.

Domain A makes Betweener Engineering™ more than a philosophy — it makes it a discipline.
