Architecture Decision Records
This directory contains Architecture Decision Records (ADRs) for Knowledge Graph System. Each ADR documents a significant architectural decision, its context, and consequences.
ADR Format
All ADRs follow a consistent format: - Status: Draft / Proposed / Accepted / Deprecated / Superseded - Date: When the decision was made - Deciders: Who made the decision - Context: The problem or situation requiring a decision - Decision: The architectural choice made - Consequences: Benefits, drawbacks, and other impacts
