+
+## Component Description
+
+### 🔵 Public API (Blue)
+- **Main Library**: Entry point for consumers
+- **V1 API**: Original schema format processing
+  - **validateJSONSchema**: Validates and normalizes JSON schemas
+  - **generateUISchema V1**: Generates UI schema from validated JSON schema
+- **V2 API**: New EarthRanger schema format processing
+  - **generateUISchema V2**: Generates UI schema from V2 schema format (automatically handles collections)
+
+### 🟣 V1 Internal Processing (Purple)
+- **JSON Processing**: Handles JSON parsing, cleaning, and formatting
+- **Schema Validation**: Validates schema structure and detects errors
+- **Number Normalization**: Converts comma decimal separators to periods
+- **Field Processing**: Processes fieldsets, checkboxes, and other field types
+- **UI Generation V1**: Creates UI schema elements from JSON schema
+
+### 🟠 V2 Internal Processing (Orange)
+- **Field Visibility Processing**: Filters deprecated and invisible fields using getVisibleFields
+- **Field Grouping by Section**: Groups visible fields by their parent sections using groupFieldsBySection
+- **Section Order Processing**: Processes sections in the order specified by the schema's ui.order array
+- **Field Control Creation**: Creates JSONForms controls for each visible field with field-type-specific options
+- **Section Layout Creation**: Creates single-column VerticalLayout sections with ordered elements (leftColumn first, then rightColumn)
+
+### 🟢 V1 Utilities (Green)
+- **V1 Utils Module**: Core utility functions for V1 processing
+- **traverseSchema**: Recursively processes nested schema objects
+- **normalizeDecimalSeparators**: Converts comma decimals (12,99 → 12.99)
+- **hasDuplicatedItems**: Detects duplicate items in arrays
+- **isRequiredProperty**: Checks if a property is required
+- **isCheckbox**: Identifies checkbox field types
+- **isFieldSet**: Identifies fieldset structures
+
+### 🔴 V2 Utilities (Pink)
+- **V2 Utils Module**: Specialized utility functions for V2 processing
+- **isFieldVisible**: Checks if field should be rendered (not deprecated)
+- **getVisibleFields**: Filters and returns all visible fields from schema
+- **groupFieldsBySection**: Groups fields by their parent section for layout processing  
+- **createControl**: Creates JSONForms control elements with field-type-specific options and collection embedding
+- **createHeaderLabel**: Creates header/label elements for sections
+- **createSectionLayout**: Creates single-column VerticalLayout optimized for React Native with ordered elements
+- **generateCollectionUISchemaInternal**: Internal function for automatic collection item UI schema generation
+
+### 🟡 Shared Schema Utilities (Yellow-Green)
+- **Schema Utils Module**: Cross-version utility functions for schema processing
+- **detectSchemaVersion**: Analyzes schema structure to determine if it's V1 or V2 format
+- **processSchema**: Processes schema string and returns version-appropriate data structure
+
+## Data Flow
+
+### V1 Flow (Original)
+1. Consumer apps import the library
+2. Raw JSON schema strings are passed to validation functions
+3. V1 processors clean, validate, and normalize the data
+4. V1 utility functions handle specific transformations
+5. Clean, validated schemas are returned to consumers
+
+### V2 Flow (New Schema Format)
+1. Consumer apps import V2 functions  
+2. Structured V2 schema objects are passed to generateUISchema
+3. **Field Visibility Processing**: getVisibleFields filters out deprecated fields
+4. **Field Grouping**: groupFieldsBySection organizes fields by their parent sections
+5. **Section Processing**: Iterate through ui.order array to process sections in specified order
+6. **Control Creation**: createControl generates JSONForms controls with field-type-specific options
+7. **Layout Creation**: createSectionLayout builds single-column VerticalLayout with ordered elements
+8. React Native optimized UI schemas with embedded collection details are returned to consumers
+
+## Key Differences
+- **V1**: Processes raw JSON strings, requires validation and normalization
+- **V2**: Processes structured schema objects, optimized for React Native single-column layouts
+- **V2**: Supports advanced features like headers, sections, collections, and field visibility
+- **V2**: Automatically embeds collection item UI schemas (no separate function calls needed)
+- **V2**: Handles all EarthRanger custom field types (TEXT, NUMERIC, CHOICE_LIST, DATE_TIME, LOCATION, COLLECTION, ATTACHMENT)
+- **V2**: Processes field constraints (maxItems/minItems, leftColumn/rightColumn layout)
+- **V2**: Mobile-first design with always-vertical layouts for React Native
+- **V2**: Compatible with JSONForms React Native custom renderers
