📝 Content Creation Workflow

1. Creator erstellt Content

// POST /api/v1/content
{
  "title": "5-Minuten Yoga",
  "description": "Bewegungspause für Grundschüler",
  "content_type": "video",
  "category": "movement",
  "license": "CC-BY-SA-4.0",
  "age_min": 6,
  "age_max": 10,
  "tags": ["yoga", "bewegung"]
}

2. Upload Media Files

// POST /api/v1/upload
FormData {
  file: <video-file.mp4>
}
→ Returns: { file_url: "http://minio:9000/..." }

3. Attach Files to Content

// POST /api/v1/content/{id}/files
{
  "file_urls": ["http://minio:9000/..."]
}

4. Publish to Matrix

// POST /api/v1/content/{id}/publish
→ Status: PUBLISHED
→ Matrix Message in #movement Space
→ Discoverable by Teachers
