Domain Coverage Matrix¶

This matrix is the compact implementation of the two-axis model. Each row starts from the problem-domain coordinate, then maps to the physical coordinate, source signals, and training focus.

Recommended Onboarding Order¶

1. Start with the System Topology so the whole system map is clear.
2. Read the Two-Axis Ontology Model so the problem and physical coordinates are clear.
3. Read the Ontology Primer so the core nouns are stable.
4. Read the Worked Example to see the model applied end to end.
5. Read Evidence, Ownership, and Lineage when the work touches feeds, projections, reports, support, or audit.
6. Read Energy Management if the work touches site power, tariffs, carbon, storage, grid signals, OSCP, OpenADR, microgrid, or operating envelopes.
7. Read the Standards and Protocol Map to understand system boundaries and the split between VDV standards.
8. Read Charge Planning and Operations if the work touches dispatch, schedules, VDV 463, or readiness.
9. Read Charging, Roaming, and Commercial Model if the work touches shared charging, tariffs, tokens, payment, or settlement.
10. Read Cross-Cutting Domains if incidents, reporting, security, support, onboarding, or user understanding could be affected.
11. Use this matrix before writing a spec or story so the right domain, physical anchors, and evidence sources are clear.
