name: obsidian-ontology-sync description: Bidirectional sync between Obsidian PKM (human-friendly notes) and structured ontology (machine-queryable graph). Automatically extracts entities and relationships from markdown, maintains ontology graph, and provides feedback to improve note structure. Run sync every few hours via cron. metadata: { "tags": ["obsidian", "ontology", "knowledge-graph", "pkm", "automation"], "openclaw": { "requires": { "skills": ["obsidian", "ontology"] } } }

Obsidian-Ontology Sync

Philosophy: Obsidian is PRIMARY (human writes natural notes) → Ontology is DERIVED (machine extracts structure) → Feedback loop improves both

Core Concept

Obsidian Notes (Markdown)
    ↓ Extract (every 3 hours)
Ontology Graph (Structured)
    ↓ Query & Analyze
Insights & Suggestions
    ↓ Feedback
Improved Note Templates

When to Use

Situation	Action
After creating/updating contacts	Run sync to extract entities
Before business queries	Sync then query ontology
Weekly review	Sync + analyze + get suggestions
New project setup	Extract entities + suggest structure
Team status tracking	Sync daily-status → ontology → analytics

What Gets Extracted

From Contact Notes (references/contacts/*.md)

Extracts:

• Person entity (name, email, phone)
• works_at → Organization
• met_at → Event
• assigned_to → Project (if mentioned)
• status → (prospect, warm_lead, client, etc.)

Example:

# Alice Johnson

**Email:** alice@company.com
**Company:** Acme Corp
**Met At:** Tech Conference 2026
**Projects:** Project Alpha

## Notes
Great developer, responsive communication.

Becomes:

{
  "entity": {
    "id": "person_alice_johnson",
    "type": "Person",
    "properties": {
      "name": "Alice Johnson",
      "email": "alice@company.com",
      "notes": "Great developer, responsive communication"
    }
  },
  "relations": [
    {"from": "person_alice_johnson", "rel": "works_at", "to": "org_acme"},
    {"from": "person_alice_johnson", "rel": "met_at", "to": "event_tech_conference_2026"},
    {"from": "person_alice_johnson", "rel": "assigned_to", "to": "project_alpha"}
  ]
}

From Client Notes (references/clients/*.md)

Extracts:

• Organization entity
• has_contract_value → number
• projects → Project entities
• primary_contact → Person

From Team Notes (references/team/*.md)

Extracts:

• Person entity
• works_for → Organization
• assigned_to → Project[]
• reports_to → Person
• response_pattern → (proactive, reactive, non-responsive)

From Daily Status (daily-status/YYYY-MM-DD/*.md)

Extracts:

• response_time property on Person
• status_update → Event
• blockers → Issue entities
• behavioral_pattern tracking

From Project Notes (projects/*.md)

Extracts:

• Project entity
• for_client → Organization
• team → Person[]
• status, value, deadline

Sync Process

1. Extract Phase (Markdown → Ontology)

# Run extraction
python3 skills/obsidian-ontology-sync/scripts/sync.py extract

# What it does:
# 1. Scan configured Obsidian directories
# 2. Parse markdown frontmatter + content
# 3. Extract entities (Person, Project, Organization, etc.)
# 4. Extract relationships (works_at, assigned_to, etc.)
# 5. Write to ontology using append-only operations

Detection Rules:

# Contact files
if file.startswith("references/contacts/"):
    entity_type = "Person"
    extract_email_from_content()
    extract_company_from_property("Company:")
    extract_projects_from_links([[Project]])
    
# Client files
if file.startswith("references/clients/"):
    entity_type = "Organization"
    extract_contract_value()
    extract_projects()
    
# Team files
if file.startswith("references/team/"):
    entity_type = "Person"
    role = "team_member"
    extract_assignments()
    extract_response_patterns()

2. Analysis Phase (Ontology → Insights)

# Run analytics
python3 skills/obsidian-ontology-sync/scripts/sync.py analyze

# Generates insights like:
# - "3 team members have no assigned projects"
# - "Contact 'John Doe' missing email address"
# - "Project 'X' has 5 people but no client linked"
# - "10 contacts from AI Summit not linked to follow-up tasks"

3. Feedback Phase (Insights → Improve PKM)

# Get suggestions
python3 skills/obsidian-ontology-sync/scripts/sync.py feedback

# Creates:
# - Missing property suggestions
# - Broken link reports
# - Relationship suggestions
# - Template improvements

Example Feedback:

# Sync Feedback - 2026-02-27

Scheduled Sync (Cron Integration)

Setup Automatic Sync

# Add to OpenClaw cron
python3 skills/obsidian-ontology-sync/scripts/setup-cron.py

# Or manually via cron tool
cron add \
  --schedule "0 */3 * * *" \
  --task "python3 skills/obsidian-ontology-sync/scripts/sync.py extract" \
  --label "Obsidian → Ontology Sync"

Cron Jobs Created:

1. Every 3 hours: Extract entities from Obsidian → Update ontology
2. Daily 9 AM: Run analytics and generate insights
3. Weekly Monday 10 AM: Generate feedback report + template suggestions

Queries (Using Ontology)

Once synced, you can query:

# All team members on high-value projects
python3 skills/ontology/scripts/ontology.py query \
  --type Person \
  --where '{"role":"team_member"}' \
  --related assigned_to \
  --filter '{"type":"Project","value__gt":400000}'

# Contacts from specific event not yet followed up
python3 skills/ontology/scripts/ontology.py query \
  --type Person \
  --where '{"met_at":"event_tech_conference_2026"}' \
  --missing has_task

# Team response patterns
python3 skills/ontology/scripts/ontology.py query \
  --type Person \
  --where '{"role":"team_member"}' \
  --aggregate response_pattern

# Projects by client
python3 skills/ontology/scripts/ontology.py query \
  --type Project \
  --group-by for_client \
  --count

Feedback Loop Examples

Example 1: Missing Email Detection

Ontology finds: Person entity with no email property

Feedback generated:

## Missing Contact Information

The following team members are missing email addresses:

- [ ] Bob (`references/team/Bob.md`)
- [ ] Lucky (`references/team/Lucky.md`)

**Suggestion:** Add email field to team member template:
\`\`\`markdown
**Email:** 
\`\`\`

Example 2: Broken Project Links

Ontology finds: Person assigned_to Project that doesn't exist

Feedback generated:

## Broken Project References

Found references to projects that don't have dedicated files:

- [ ] "Project Epsilon" mentioned in team files but no `projects/Project Epsilon.md`
- [ ] "Project Delta Tata DT" assigned but no project file

**Suggestion:** Create project files with template

Example 3: Relationship Discovery

Ontology finds: Multiple people working at same company

Feedback generated:

## Suggested Company Grouping

Found 3 contacts at "TechHub":
- Jane Doe
- [2 others from daily-status mentions]

**Suggestion:** Create `references/clients/TechHub.md` and link contacts

Integration with Daily Workflow

Morning Routine (9 AM)

# Cron runs analysis
# Generates daily-insights.md with:
- Response rate from yesterday's status requests
- Projects needing attention (blockers mentioned)
- Contacts to follow up (met > 3 days ago, no task)

Weekly Review (Monday 10 AM)

# Cron generates weekly feedback
# Creates suggestions for:
- Missing information to fill in
- Broken links to fix
- New templates to adopt
- Relationship insights

On-Demand Queries

# Before a meeting
"Show me all interactions with Client X"

# Resource planning
"Which team members are on <3 projects?"

# Sales pipeline
"Contacts met at conferences in last 30 days without follow-up"
