UKFS Specification Review - Background

Document Under Review

Universal Knowledge Filesystem (UKFS) v0.1.0 - A hierarchical directory-based architecture for organizing arbitrary knowledge in a format optimized for autonomous agent navigation.

Core Innovation

Unlike RAG (probabilistic embedding similarity) or Tool-Based Retrieval (query languages), UKFS enables deterministic semantic path traversal - agents reason about knowledge location rather than search for it.

Current Specification

Root Directory Structure

/{root}/
├── .spec/    # UKFS specification metadata
├── e/        # ENTITIES (nouns)
├── r/        # RELATIONS (edges)
├── t/        # TIMELINE (events)
├── s/        # STATE (current snapshots)
├── p/        # PROCEDURES (how-to)
└── q/        # QUERIES (cached Q&A)

Entity Types (/e/)

  • person, org, place, concept, project, asset, task, word

Relation Convention

{subject}+{object}.yaml in /r/{relation-type}/

Design Principles

  1. Path as identifier (human-readable, greppable)
  2. No UUIDs in paths (speakable, memorable)
  3. Type as namespace (disambiguation through hierarchy)
  4. English structure, universal content
  5. Relations as first-class files
  6. State separation (current vs timeless)

Agent Navigation Algorithm (8 steps)

  1. Parse query for entity references and intent
  2. Identify relevant entity types
  3. Resolve entity paths: /e/{type}/{slug}/
  4. Find relations: /r/{relation-type}/{entity}.yaml
  5. Check state if "current": /s/
  6. Check timeline if temporal: /t/
  7. Check procedures if "how to": /p/
  8. Synthesize response

Key Questions for Deliberation

  1. Naming Convention: Single-character (e/, r/, t/, s/, p/, q/) vs full names (entities/, relations/...)

    • Trade-offs: brevity vs discoverability vs agent navigation efficiency

  2. Entity Type Coverage: Are person, org, place, concept, project, asset, task, word sufficient?

  3. Relation Modeling: Is {subject}+{object}.yaml adequate? What about:

    • N-ary relations (3+ participants)
    • Relation attributes
    • Bidirectional relations

  4. State vs Timeline: Is /s/ vs /t/ separation clear? Edge cases?

  5. Query Caching (/q/): Staleness concerns? Invalidation strategy?

  6. Scalability: Millions of entities? Sharding strategies?

  7. Agent Navigation: Is the 8-step algorithm complete? Disambiguation? Fallbacks?

  8. Git Integration: Merge conflicts? Concurrent edits?

  9. Security/Privacy: Access control? Encryption?

  10. Missing Concepts: What fundamental categories are absent?

Success Criteria

The dialogue should produce concrete, actionable improvements to the UKFS specification that maintain its core philosophy (deterministic semantic navigation) while addressing practical concerns.
