## Notes
- **Authentication:** Most new examples will need enterprise/API key auth (except vector_tiles, map_service_basics which can use public services)
- **Service Access:** Geoprocessing, Places, Elevation, Image Service examples require access to specific services
- **Complexity:** Async geoprocessing and version branching examples are more complex
- **Documentation:** Each example should follow established pattern with demonstration functions and best practices section
---
## Success Metrics
A well-rounded example suite should:
- ✅ Cover all 12 major service clients
- ✅ Demonstrate both public and enterprise scenarios
- ✅ Show sync and async patterns
- ✅ Include error handling examples
- ✅ Progress from simple to advanced operations
- ✅ Provide copy-paste starting points for common tasks
**Target:** 20 examples covering 80%+ of implemented operations
