Best Practices

Documentation

1. Be specific - Describe what the data represents
2. Include examples - Show sample values when helpful
3. Note caveats - Document known issues or limitations
4. Keep updated - Review descriptions quarterly

Tagging

1. Use standard tags - Follow organizational taxonomy
2. Apply tiers - Indicate business importance
3. Tag consistently - Same data, same tags
4. Don't over-tag - Keep tags meaningful

Ownership

1. Assign owners early - During ingestion if possible
2. Use teams - Better than individual users
3. Review regularly - Update when people change roles
4. Document expectations - What ownership means

Glossary

1. Start small - Core terms first
2. Get buy-in - Involve business stakeholders
3. Use approval workflows - For governed terms
4. Link to assets - Make terms discoverable
