Architecture Knowledge Graph Development

Summary

Development of an Architecture Knowledge Graph for cross-project relationship modeling and lineage analysis.

Details

The vision identifies a need for an 'Architecture Intelligence Layer'. This work item involves transitioning from isolated project-level artifacts to a unified graph-based representation of architectural knowledge, enabling complex queries across projects and time.

Decision

Proposed: Adopt a graph-based schema for representing relationships between ADRs, Patterns, Signals, and Code artifacts.

Rationale

Current artifacts are siloed. A Knowledge Graph enables the system to reason about the impact of a pattern change in one project on the reliability of another, fulfilling the 'Continuous Intelligence' vision.

Implementation Plan

  1. Define the Graph Schema (Nodes: Decision, Pattern, Signal, Artifact). 2. Implement Knowledge Providers for graph ingestion. 3. Develop query interfaces for the Alignment Engine.

Alternatives Considered

['Relational database storage (rejected due to the complexity of recursive relationship traversal)', 'Enhanced flat-file indexing (rejected as insufficient for multi-hop lineage analysis)']

Risks

['Complexity of maintaining graph consistency across distributed projects', 'Performance overhead of graph traversal during runtime reasoning']

Expected Outcomes

Ability to perform cross-project impact analysis; visual lineage of architectural decisions; improved signal-to-pattern promotion accuracy.

Dependencies
