## 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
