+
+
+      Filmmateriaal is kwetsbaar en vernietigt op den duur zichzelf. Oude films vervagen,
+      verkleuren en verbrokkelen. Het materiaal is gevoelig voor schommelingen in
+      temperatuur en luchtvochtigheid. Daarom is het belangrijk dat film wordt bewaard
+      in een depot onder goede klimaatbeheersing. Conservering is dus echt noodzakelijk
+      en dat doen wij als Drents Archief.
+
+
+      Het Drents Archief zet de oude films en geluidsbanden over op moderne digitale
+      dragers. Het originele materiaal kan op die manier onder de beste omstandigheden
+      in het depot bewaard blijven.'

+    description: '"Weet uw moeder wel dat u zo''n duur huis heeft gekocht?" Ook Drentse
+      vrouwen werden steeds zelfstandiger, ze kregen fulltimebanen – soms zelfs als
+      kostwinner, en er ontstonden speciale vrouwencafés, zoals op maandagavonden
+      in Het Keldertje in Hoogeveen. Niet iedereen was blij met deze ontwikkelingen.
+      Er werd vreemd gekeken naar vrouwen die zelfstandig een huis kochten. En ook
+      samenkomsten waarin vrouwen spraken over alles wat hen bezighield, waren voor
+      veel mannen onbegrijpelijk.  '

+      en melken. Steeds meer van hen sloten zich ook aan bij de plattelandsvrouwen

+# YouTube Enrichment for Heritage Custodians
+
+This document explains how to enrich heritage custodian entries with YouTube channel and video data.
+
+## Prerequisites
+
+### 1. Get a YouTube API Key
+
+1. **Go to Google Cloud Console**
+   - Visit: https://console.cloud.google.com/
+
+2. **Create or Select a Project**
+   - Click on the project dropdown at the top
+   - Click "New Project" or select an existing one
+   - Name it something like "GLAM YouTube Enrichment"
+
+3. **Enable YouTube Data API v3**
+   - Navigate to "APIs & Services" → "Library"
+   - Search for "YouTube Data API v3"
+   - Click on it and press **Enable**
+
+4. **Create API Credentials**
+   - Go to "APIs & Services" → "Credentials"
+   - Click "Create Credentials" → "API Key"
+   - Copy the generated API key
+
+5. **Restrict the API Key (Recommended)**
+   - Click on your new API key to edit it
+   - Under "API restrictions", select "Restrict key"
+   - Select only "YouTube Data API v3"
+   - Click Save
+
+### 2. Set Environment Variable
+
+```bash
+export YOUTUBE_API_KEY='your-api-key-here'
+```
+
+Or add to your `.env` file:
+```
+YOUTUBE_API_KEY=your-api-key-here
+```
+
+### 3. Install Dependencies
+
+```bash
+pip install httpx pyyaml
+
+# For transcript extraction (optional but recommended)
+brew install yt-dlp  # macOS
+# or
+pip install yt-dlp
+```
+
+## Usage
+
+### Basic Usage
+
+```bash
+# Process all entries with YouTube URLs
+python scripts/enrich_youtube.py
+
+# Dry run (show what would be done)
+python scripts/enrich_youtube.py --dry-run
+
+# Process only first 10 entries
+python scripts/enrich_youtube.py --limit 10
+
+# Process a specific entry
+python scripts/enrich_youtube.py --entry 0146_Q1663974.yaml
+```
+
+### Example Output
+
+```
+Processing: 0146_Q1663974.yaml
+  Found YouTube URL: https://www.youtube.com/user/TUApeldoorn
+    Fetching channel info for UCxxxxx...

+```
+
+## Data Collected

+
+## Provenance Tracking
+
+All extracted data includes full provenance:
+
+```yaml

+      transcript:
+        transcript_text: "Full video transcript..."
+        language: nl
+        transcript_type: auto
+```
+
+## API Quota
+
+YouTube Data API has a daily quota of **10,000 units**:
+
+| Operation | Cost |
+|-----------|------|
+| Channel info | 1 unit |
+| Video list | 1 unit |
+| Video details | 1 unit per video |
+| Comments | 1 unit per 100 comments |
+| Search | 100 units |
+
+**Estimated usage per custodian**: 15-50 units (depending on videos/comments)
+
+For 100 custodians: ~1,500-5,000 units (well within daily quota)
+
+## Troubleshooting
+
+### "API key not valid"
+- Check that the API key is correct
+- Verify YouTube Data API v3 is enabled
+- Check that the key isn't restricted to wrong APIs
+
+### "Quota exceeded"
+- Wait until the next day (quota resets at midnight Pacific Time)
+- Or request a quota increase in Google Cloud Console
+
+### "Channel not found"
+- The channel may have been deleted
+- The URL format may not be recognized
+- Try using the channel ID directly
+
+### "Comments disabled"
+- Some videos have comments disabled
+- The script handles this gracefully
+
+### "No transcript available"
+- Not all videos have captions
+- Auto-generated captions may not be available for all languages
+
+## Architecture

+## API Methods Used
+
+| Platform  | Method                    | Authentication        |
+|-----------|---------------------------|----------------------|
+| YouTube   | YouTube Data API v3       | API Key              |
+| YouTube   | yt-dlp (fallback)        | None                 |
+| LinkedIn  | Voyager API (unofficial) | Session Cookie       |
+| Facebook  | Graph API                | Page Access Token    |
+| Instagram | Graph API (via Facebook) | Access Token         |
+
+## Rate Limits
+
+- **YouTube**: 10,000 quota units/day (search costs 100, video info costs 1)
+- **LinkedIn**: Unofficial API - use sparingly to avoid account restrictions
+- **Facebook/Instagram**: 200 calls/user/hour for most endpoints
+
+## Troubleshooting
+
+### YouTube: "API key not configured"
+- Set `YOUTUBE_API_KEY` or install `yt-dlp` for fallback
+
+### LinkedIn: "Session expired"
+- Get a fresh `li_at` cookie from your browser
+
+### Facebook/Instagram: "Invalid access token"
+- Tokens expire after ~60 days; generate a new one
+
+### yt-dlp: "Command not found"
+```bash
+brew install yt-dlp  # macOS
+pip install yt-dlp   # All platforms
+```

+Social Media MCP Server - Unified Media Content Extraction
+
+Provides tools to obtain media content from:
+1. YouTube - Video info, transcripts, channel data, search
+2. LinkedIn - Profile scraping, job search, company info, feed posts
+3. Facebook - Page posts, comments, insights, messaging
+4. Instagram - Business profile, media posts, insights, DMs
+
+Architecture:
+- Uses official APIs where available (YouTube Data API, Facebook Graph API, Instagram Graph API)
+- Uses unofficial/scraping methods for LinkedIn (no official API for content reading)
+- Supports authentication via environment variables
+
+Environment Variables:
+- YOUTUBE_API_KEY: YouTube Data API v3 key
+- LINKEDIN_EMAIL: LinkedIn login email
+- LINKEDIN_PASSWORD: LinkedIn login password  
+- LINKEDIN_COOKIE: LinkedIn session cookie (li_at) - alternative to email/password
+- FACEBOOK_ACCESS_TOKEN: Facebook Page Access Token
+- FACEBOOK_PAGE_ID: Facebook Page ID
+- INSTAGRAM_ACCESS_TOKEN: Instagram Business Account Token
+- INSTAGRAM_BUSINESS_ACCOUNT_ID: Instagram Business Account ID
+
+Based on patterns from:
+- https://github.com/anaisbetts/mcp-youtube
+- https://github.com/ZubeidHendricks/youtube-mcp-server

+YouTube Enrichment Script for Heritage Custodian Entries
+
+This script enriches heritage custodian YAML entries with YouTube channel/video data.
+It finds YouTube channels from existing web_claims (social_youtube) and fetches:
+- Channel info (subscribers, video count, description, etc.)
+- Recent videos (title, description, views, likes, comments)
+- Video transcripts (when available)
+- Comments on videos
+
+All data includes full provenance with URLs and timestamps.
+
+Usage:
+    python scripts/enrich_youtube.py [--dry-run] [--limit N] [--entry ENTRY_FILE]
+
+Environment Variables:
+    YOUTUBE_API_KEY: Required. Get from https://console.cloud.google.com/

+Generate Mermaid ER diagrams with instance data from LinkML schemas.
+
+This script extends the standard Mermaid generation to include:
+1. All classes and their relationships
+2. Enum values (from LinkML schema)
+3. Instance data (from instances/enums/*.yaml) as annotations
+
+The instance data provides semantically meaningful "allowed values" for
+CustodianType classes like MuseumType, LibraryType, HeritageSocietyType, etc.
+
+Usage:
+    python3 scripts/generate_mermaid_with_instances.py
