📖 Curated Vocabularies

Using curated, controlled vocabularies developed through national and international earth‑science semantic networks, is a key step in data curation.

Standardized vocabularies ensure data is:

  • ✅ Consistent → terms mean the same thing across datasets
  • ✅ Unambiguous → reduces confusion in interpretation
  • ✅ Interoperable → reusable across systems and repositories

Simply put, they provide a common language for describing data.

📚 Standardized Terms Used by CanWIN

Below are the main controlled vocabularies you’ll encounter when publishing or viewing data in CanWIN.
