​
Notes

  • Coverage analysis is computationally intensive and may take longer for comprehensive queries
  • Quality analysis requires mapping metadata and may not be available for all vocabulary pairs
  • Trends analysis requires historical data spanning multiple vocabulary releases
  • Recommendations are generated based on gap analysis and usage patterns
  • Coverage thresholds help identify vocabularies needing mapping improvements
  • Orphaned vocabularies may require custom mapping strategies
  • Domain coverage varies significantly based on vocabulary specialization
  • Regular coverage monitoring helps identify degradation over time
