Analysis Methodology

Reference File

Path: /Users/nickviljoen/Downloads/asset_representation.json Source: Client-provided reference payload Fields: 31 total fields

Code Base

Path: /Users/nickviljoen/Desktop/Ferrero/ferrero-opentext/Python-Version/scripts/shared/metadata_extractor_mvp.py Primary Function: build_mvp_asset_representation() Lines: 86-148 (main), supporting functions through line 818

Fields Analyzed

Total: 14 fields (45% coverage) Breakdown:

• 5 Tabular fields (100% of type)
• 3 Domain fields (representative sample)
• 2 Date fields (100% of type)
• 2 Text fields (representative sample)
• 2 System fields (representative sample)

Coverage: All field types represented

---

Key Findings

Perfect Matches ✅

1. All Tabular Fields (5/5)

   • Correct MetadataTableField type
   • Correct parent_table_id references
   • Correct DomainValue/CascadingDomainValue types
   • All properties present

2. All Domain Fields (3/3)

   • Full DomainValue wrapper
   • All 10 properties present
   • Correct active_from/active_to values
   • Correct display_value logic

3. All Date Fields (2/2)

   • Correct string type (not date object)
   • Correct MM/DD/YYYY format
   • Proper value nesting

4. All Text Fields (2/2)

   • Simple value.value structure
   • String type
   • No extra wrappers

Minor Differences ⚠️

1. System Fields (2/2)

   • Missing: cascading_domain_value, domain_value, is_locked at top level
   • Impact: Minimal (system fields, likely added by DAM)
   • Recommendation: Optional enhancement

2. Property Order

   • Different order in nested objects
   • Impact: None (JSON objects are unordered)
   • Recommendation: No action required
