Versioned Relationship Snapshots

Time-Aware KnowledgeRelationship Integrity

Preserve the exact context and relationships that existed when each note version was created. Every version maintains a snapshot of its knowledge connections, ensuring historical accuracy and temporal consistency.

The Challenge

Traditional note systems lose historical context

When relationships change, old note versions become misleading and lose their original meaning

❌ Traditional Approach

January 1st - Meeting Note v1

“Discussed API strategy, see PROJECT-PLAN-5 for details”

January 15th - Project Plan Updated

PROJECT-PLAN-5 completely rewritten, original strategy removed

Result: Context Lost!

Meeting Note v1 now points to wrong information. Original context is gone forever.

✅ Versioned Relationship Snapshots

Meeting Note v1 → Project Plan v2

Snapshot preserves original API strategy context

Meeting Note v2 → Project Plan v3

New snapshot points to updated strategy

Result: Perfect Integrity!

Both versions maintain their original context. History is preserved.

Architecture

How relationship snapshots work

Every note version captures the exact state of relationships at creation time

Version-Level Relationships

Instead of note-to-note relationships, we create version-to-version snapshots that preserve exact states.

Temporal Consistency

Each version maintains relationships to the specific versions that existed when it was created, like Git submodules.

Immutable History

Once created, relationship snapshots never change, ensuring historical accuracy and audit trails.

Powerful Benefits

Why relationship snapshots matter

Historical Accuracy
View any note version and see the exact relationships and context that existed when it was created. No retroactive changes distort the historical record.
Context Preservation
Understand why decisions were made and what information was available at specific points in time. Critical for project retrospectives and learning.
Evolution Tracking
Follow how ideas and relationships evolved over time. See when connections were made, changed, or removed with complete audit trails.
Version Isolation
Each version exists in isolation with its own relationship snapshot. Changes don’t corrupt earlier versions or create confusion.

Real-World Applications

Where this makes a difference

Critical scenarios where relationship integrity matters most

📋 Project Evolution

  • • Meeting notes reference specific project plan versions
  • • Decision records link to relevant research at that time
  • • Retrospectives accurately reflect what was known when
  • • Blame-free understanding of why decisions were made

🔬 Research & Analysis

  • • Literature reviews maintain citation integrity over time
  • • Hypothesis notes link to the data that influenced them
  • • Analysis conclusions preserve their original evidence
  • • Research evolution tracking for meta-analysis

⚖️ Compliance & Auditing

  • • Regulatory decisions link to specific policy versions
  • • Audit trails show what information was available when
  • • Compliance records maintain immutable relationships
  • • Historical accuracy for legal requirements

🎓 Learning & Knowledge

  • • Course materials reference correct resource versions
  • • Student notes link to assignments as they existed
  • • Knowledge evolution tracking for improved learning
  • • Understanding how concepts developed over time

Implementation

How we built it

Advanced database design for temporal relationship integrity

Database Schema

version_relationships {
sourceVersionId: Note A v1
targetVersionId: Note B v2
relationshipType: “references”
snapshotCreatedAt: timestamp
}

Automatic Snapshot Creation

When you create a new note version, the system automatically:

  • • Identifies all related notes mentioned in the content
  • • Captures the current version ID of each related note
  • • Creates immutable relationship records to those specific versions
  • • Ensures future changes don’t affect historical connections

Query Intelligence

When viewing any note version, the system shows:

  • • Relationships as they existed at that point in time
  • • Links to the exact versions that were current then
  • • Context that makes sense for that historical moment
  • • Evolution indicators showing what changed later

Experience temporal integrity

Start creating notes with versioned relationship snapshots and never lose historical context again.
