+## Serialization Mechanisms Verified
+
+### 1. JSON Serialization (Primary)
+
+#### DateInfo Class
+**Methods**: `toArray()`, `initFromArray()`, `__construct(array)`
+
+✅ **confidence property**
+```php
+$date->setConfidence(ConfidenceLevel::HIGH);
+$array = $date->toArray();
+// Result: ["confidence" => "http://gedcomx.org/High"]
+
+$restored = new DateInfo($array);
+// Result: $restored->getConfidence() === "http://gedcomx.org/High"
+```
+
+✅ **calendar property**
+```php
+$date->setCalendar(CalendarType::GREGORIAN);
+$array = $date->toArray();
+// Result: ["calendar" => "http://gedcomx.org/Gregorian"]
+
+$restored = new DateInfo($array);
+// Result: $restored->getCalendar() === "http://gedcomx.org/Gregorian"
+```
+
+✅ **alternateCalendarDates property (nested array)**
+```php
+$primaryDate->setAlternateCalendarDates([$julianDate, $hebrewDate]);
+$array = $primaryDate->toArray();
+// Result: [
+// "alternateCalendarDates" => [
+// ["original" => "...", "calendar" => "..."],
+// ["original" => "...", "calendar" => "..."]
+// ]
+// ]
+
+$restored = new DateInfo($array);
+// Result: count($restored->getAlternateCalendarDates()) === 2
+// Each element is a DateInfo instance
+```
+
+#### FamilyView Class
+**Methods**: `toArray()`, `initFromArray()`, `__construct(array)`
+
+✅ **parent1 property**
+```php
+$familyView->setParent1($parent1);
+$array = $familyView->toArray();
+// Result: ["parent1" => ["resource" => "..."]]
+
+$restored = new FamilyView($array);
+// Result: $restored->getParent1() instanceof ResourceReference
+```
+
+✅ **parent2 property**
+```php
+$familyView->setParent2($parent2);
+$array = $familyView->toArray();
+// Result: ["parent2" => ["resource" => "..."]]
+
+$restored = new FamilyView($array);
+// Result: $restored->getParent2() instanceof ResourceReference
+```
+
+✅ **children property (array)**
+```php
+$familyView->setChildren([$child1, $child2]);
+$array = $familyView->toArray();
+// Result: [
+// "children" => [
+// ["resource" => "..."],
+// ["resource" => "..."]
+// ]
+// ]
+
+$restored = new FamilyView($array);
+// Result: count($restored->getChildren()) === 2
+```
+
+---
+
+### 2. XML Serialization
+
+#### DateInfo Class
+**Methods**: `writeXmlContents()`, `setKnownChildElement()`, `__construct(XMLReader)`
+
+✅ **XML Write - confidence**
+```xml
+
+ http://gedcomx.org/High
+
+```
+
+✅ **XML Write - calendar**
+```xml
+
+ http://gedcomx.org/Gregorian
+
+```
+
+✅ **XML Write - alternateCalendarDates (nested)**
+```xml
+
+ 1752-01-10
+ http://gedcomx.org/Gregorian
+
+ 1751-12-30
+ http://gedcomx.org/Julian
+
+
+```
+
+✅ **XML Read - All properties parsed correctly**
+```php
+$xml = '
+ http://gedcomx.org/Medium
+ http://gedcomx.org/Julian
+';
+
+$reader = new XMLReader();
+$reader->XML($xml);
+$date = new DateInfo($reader);
+
+// Result: All properties correctly populated
+```
+
+#### FamilyView Class
+**Methods**: `writeXmlContents()`, `setKnownChildElement()`, `__construct(XMLReader)`
+
+✅ **XML Write - parent1, parent2, children**
+```xml
+
+
+
+
+
+
+```
+
+✅ **XML Read - All properties parsed correctly**

+## Real-World Usage Examples
+
+### Example 1: Complete JSON Round-Trip
+
+```php
+use Gedcomx\Conclusion\DateInfo;
+use Gedcomx\Types\CalendarType;
+use Gedcomx\Types\ConfidenceLevel;
+
+// Create DateInfo with all properties
+$date = new DateInfo();
+$date->setOriginal('10 January 1752');
+$date->setFormal('+1752-01-10');
+$date->setCalendar(CalendarType::GREGORIAN);
+$date->setConfidence(ConfidenceLevel::HIGH);
+
+// Add alternate calendar
+$julianDate = new DateInfo();
+$julianDate->setOriginal('30 December 1751');
+$julianDate->setCalendar(CalendarType::JULIAN);
+$date->setAlternateCalendarDates([$julianDate]);
+
+// Serialize to JSON
+$json = json_encode($date->toArray());
+
+// Deserialize from JSON
+$restored = new DateInfo(json_decode($json, true));
+
+// Verify all data preserved
+assert($restored->getOriginal() === '10 January 1752');
+assert($restored->getCalendar() === CalendarType::GREGORIAN);
+assert($restored->getConfidence() === ConfidenceLevel::HIGH);
+assert(count($restored->getAlternateCalendarDates()) === 1);
+assert($restored->getAlternateCalendarDates()[0]->getCalendar() === CalendarType::JULIAN);
+```
+
+### Example 2: FamilyView JSON Round-Trip
+
+```php
+use Gedcomx\Conclusion\FamilyView;
+use Gedcomx\Common\ResourceReference;
+
+// Create family
+$family = new FamilyView();
+$family->setId('SMITH-FAMILY');
+
+$father = new ResourceReference();

+$family->setParent1($father);
+
+$mother = new ResourceReference();
+$mother->setResource('https://familysearch.org/persons/MARY-JONES');
+$family->setParent2($mother);
+
+$child = new ResourceReference();
+$child->setResource('https://familysearch.org/persons/JAMES-SMITH');
+$family->addChild($child);
+
+// Serialize to JSON
+$json = json_encode($family->toArray());
+
+// Deserialize from JSON
+$restored = new FamilyView(json_decode($json, true));
+
+// Verify all data preserved
+assert($restored->getId() === 'SMITH-FAMILY');
+assert($restored->getParent1()->getResource() === 'https://familysearch.org/persons/JOHN-SMITH');
+assert($restored->getParent2()->getResource() === 'https://familysearch.org/persons/MARY-JONES');
+assert(count($restored->getChildren()) === 1);
+```
+
+### Example 3: Person with Enhanced DateInfo
+
+```php
+use Gedcomx\Conclusion\Person;
+use Gedcomx\Conclusion\Fact;
+use Gedcomx\Conclusion\DateInfo;
+use Gedcomx\Types\CalendarType;
+use Gedcomx\Types\ConfidenceLevel;
+
+// Create person with birth fact
+$person = new Person();
+$person->setId('PERSON-1');
+
+$birthFact = new Fact();
+$birthFact->setType('http://gedcomx.org/Birth');
+
+$birthDate = new DateInfo();
+$birthDate->setOriginal('25 December 1800');
+$birthDate->setFormal('+1800-12-25');
+$birthDate->setCalendar(CalendarType::GREGORIAN);
+$birthDate->setConfidence(ConfidenceLevel::HIGH);
+
+$birthFact->setDate($birthDate);
+$person->setFacts([$birthFact]);
+
+// Serialize entire person to JSON
+$json = json_encode($person->toArray());
+
+// Deserialize
+$restored = new Person(json_decode($json, true));
+
+// Verify nested data preserved
+assert($restored->getFacts()[0]->getDate()->getCalendar() === CalendarType::GREGORIAN);
+assert($restored->getFacts()[0]->getDate()->getConfidence() === ConfidenceLevel::HIGH);
+```
+

+
+## Edge Cases Tested
+
+✅ **Null Properties**
+- Properties not set remain null
+- Serialization excludes null properties
+- Deserialization handles missing properties
+
+✅ **Empty Arrays**
+- Empty children array serializes correctly
+- Empty alternateCalendarDates array handled
+
+✅ **Optional Properties**
+- parent2 can be null (single-parent family)
+- alternateCalendarDates can be null
+- confidence can be null
+
+✅ **Nested Objects**
+- alternateCalendarDates (DateInfo[]) serializes recursively
+- children (ResourceReference[]) serializes correctly
+- Multi-level nesting works
+
+✅ **Enum Values**
+- CalendarType constants serialize as URIs
+- ConfidenceLevel constants serialize as URIs
+- Deserialization preserves URI strings
+

-
-### 📊 Coverage Metrics
-
-- **Lines Covered:** Measured by CI with Xdebug on PHP 8.3
-- **Test Execution Time:** < 35ms (average)
-- **Memory Usage:** ~15MB peak
-- **CI Status:** [](https://github.com/FamilySearch/gedcomx-php/actions)
-
-## Test Patterns Used
-
-### 1. Construction Tests
-Verify objects can be created and basic properties set/get correctly.
-
-### 2. Array Construction Tests
-Verify models can be constructed from associative arrays (JSON deserialization).
-
-### 3. Property Tests
-Verify all major properties have working getters and setters.
-
-### 4. Collection Tests
-Verify models that contain collections (names, facts, etc.) handle arrays correctly.
-
-### 5. JSON Round-trip Tests
-Verify models serialize to JSON and deserialize back correctly:
-```
-Model → toJson() → json_decode() → new Model() → verify properties match
-```
-
-### 6. XML Serialization Tests
-Verify XML output contains expected elements and structure.
-
-## Models Not Yet Covered
-
-The following models exist but don't yet have dedicated tests (they may be tested indirectly):
-
-**Records Models:**
-- RecordSet, Record, Field, FieldValue, FieldDescriptor, Collection, CollectionContent
-
-**Search Models:**
-- SearchResult, SearchResultEntry
-
-**Platform-Specific:**
-- ChangeInfo, ChangeOperation, Merge, MergeConflict, MergeAnalysis
-- MatchInfo, MatchStatus, ArtifactMetadata
-
-**Note:** These models represent specialized functionality (record indexing, search results, merge operations) that may have lower usage in typical SDK applications. Test coverage for these can be added as needed based on usage patterns.
-
-## Adding New Tests
-
-When adding new models or features, ensure tests cover:
-
-1. ✅ Basic construction
-2. ✅ Array/JSON construction
-3. ✅ All public getters/setters
-4. ✅ JSON serialization
-5. ✅ JSON deserialization (round-trip)
-6. ✅ XML serialization (if applicable)
-7. ✅ Edge cases (null values, empty collections)
-
-See `tests/unit/ConclusionModelsTests.php` for examples.

+## FamilyView Class
+
+### FamilyView Overview
+
+The `FamilyView` class provides a convenient way to represent a family unit with parents and children for display purposes. It groups family members together without requiring explicit relationship definitions.
+
+**Namespace**: `Gedcomx\Conclusion\FamilyView`
+
+**Key Features**:
+- Represents family groupings with up to two parents
+- Supports any number of children
+- Single-parent families supported
+- JSON and XML serialization
+- Lightweight view model (not a formal relationship)
+
+### When to Use FamilyView
+
+**Use FamilyView when:**
+- ✅ Displaying family groups in a UI
+- ✅ Creating family tree visualizations
+- ✅ Organizing persons into family units
+- ✅ Representing household structures
+- ✅ Building pedigree charts
+
+**Use Relationship class when:**
+- ❌ Defining formal couple relationships
+- ❌ Specifying parent-child relationships with facts
+- ❌ Recording relationship evidence
+- ❌ Capturing relationship dates and places
+
+**Key Difference**: FamilyView is a **view/display model**, while Relationship is a **conclusion model** with evidence and sources.
+
+### FamilyView Basic Usage
+
+#### Creating a Simple Family
+
+```php
+setId('SMITH-FAMILY-1850');
+
+// Add first parent (father)
+$father = new ResourceReference();
+$father->setResource('https://familysearch.org/platform/persons/JOHN-SMITH-1820');
+$family->setParent1($father);
+
+// Add second parent (mother)
+$mother = new ResourceReference();
+$mother->setResource('https://familysearch.org/platform/persons/MARY-JONES-1825');
+$family->setParent2($mother);
+
+// Add children
+$child1 = new ResourceReference();
+$child1->setResource('https://familysearch.org/platform/persons/JAMES-SMITH-1845');
+$family->addChild($child1);
+
+$child2 = new ResourceReference();
+$child2->setResource('https://familysearch.org/platform/persons/SARAH-SMITH-1847');
+$family->addChild($child2);
+
+$child3 = new ResourceReference();
+$child3->setResource('https://familysearch.org/platform/persons/WILLIAM-SMITH-1850');
+$family->addChild($child3);
+
+// The family now has 2 parents and 3 children
+echo "Family has " . count($family->getChildren()) . " children\n";
+```
+
+#### Creating a Single-Parent Family
+
+```php
+setId('JONES-FAMILY-1900');
+
+// Only one parent
+$parent = new ResourceReference();
+$parent->setResource('https://familysearch.org/platform/persons/ELIZABETH-JONES-1880');
+$family->setParent1($parent);
+// parent2 remains null
+
+// Add children
+$child = new ResourceReference();
+$child->setResource('https://familysearch.org/platform/persons/ROBERT-JONES-1905');
+$family->addChild($child);
+
+// Single-parent family created
+```
+
+### FamilyView Advanced Examples
+
+#### Example 1: Building a Family from Person Objects
+
+```php
+setId('JOHN-SMITH-1820');
+
+$maryPerson = new Person();
+$maryPerson->setId('MARY-JONES-1825');
+
+// Create FamilyView from Person IDs
+$family = new FamilyView();
+$family->setId('SMITH-FAMILY');
+
+$fatherRef = new ResourceReference();
+$fatherRef->setResourceId($johnPerson->getId());
+$fatherRef->setResource('#' . $johnPerson->getId()); // Local reference
+$family->setParent1($fatherRef);
+
+$motherRef = new ResourceReference();
+$motherRef->setResourceId($maryPerson->getId());
+$motherRef->setResource('#' . $maryPerson->getId());
+$family->setParent2($motherRef);
+```
+
+#### Example 2: Serializing to JSON
+
+```php
+setId('FAMILY-JSON-EXAMPLE');
+
+$parent1 = new ResourceReference();
+$parent1->setResource('P-1');
+$family->setParent1($parent1);
+
+$child = new ResourceReference();
+$child->setResource('C-1');
+$family->addChild($child);
+
+// Convert to JSON
+$json = json_encode($family->toArray(), JSON_PRETTY_PRINT);
+echo $json;
+```
+
+**Output**:
+```json
+{
+ "id": "FAMILY-JSON-EXAMPLE",
+ "parent1": {
+ "resource": "P-1"
+ },
+ "children": [
+ {
+ "resource": "C-1"
+ }
+ ]
+}
+```
+
+#### Example 3: Deserializing from JSON
+
+```php
+getParent1()->getResource() . "\n";
+echo "Parent 2: " . $family->getParent2()->getResource() . "\n";
+echo "Children: " . count($family->getChildren()) . "\n";
+```
+
+#### Example 4: Bulk Children Assignment
+
+```php
+setResource("https://familysearch.org/persons/CHILD-{$i}");
+ $children[] = $child;
+}
+
+// Create family and set all children at once
+$family = new FamilyView();
+$family->setChildren($children);
+
+// All 5 children added
+echo "Total children: " . count($family->getChildren()) . "\n";
+```
+
+---
+
+## Calendar Type Support
+
+### Calendar Overview
+
+The GEDCOM X PHP SDK now supports multiple calendar systems, allowing you to represent dates in various historical and cultural calendars. This is essential for accurate genealogical research across different time periods and cultures.
+
+**Namespace**: `Gedcomx\Types\CalendarType`
+
+### Available Calendar Types
+
+```php
+setOriginal('25 December 1800');
+$date->setFormal('+1800-12-25');
+$date->setCalendar(CalendarType::GREGORIAN);
+
+echo $date->getCalendar(); // "http://gedcomx.org/Gregorian"
+```
+
+#### Using Different Calendars
+
+```php
+setOriginal('15 Shevat 5780');
+$hebrewDate->setCalendar(CalendarType::HEBREW);
+
+// Julian calendar date (pre-Gregorian reform)
+$julianDate = new DateInfo();
+$julianDate->setOriginal('3 September 1752');
+$julianDate->setFormal('+1752-09-03');
+$julianDate->setCalendar(CalendarType::JULIAN);
+
+// Islamic calendar date
+$hijriDate = new DateInfo();
+$hijriDate->setOriginal('1 Muharram 1444');
+$hijriDate->setCalendar(CalendarType::HIJRI);
+```
+
+### Alternate Calendar Dates
+
+One of the most powerful features is the ability to represent the same date in multiple calendar systems. This is crucial for historical accuracy during calendar transitions.
+
+#### Example: Gregorian Calendar Switch (1752)
+
+When Britain adopted the Gregorian calendar in 1752, 11 days were skipped (September 3-13, 1752).
+
+```php
+setOriginal('14 September 1752');
+$gregorianDate->setFormal('+1752-09-14');
+$gregorianDate->setCalendar(CalendarType::GREGORIAN);
+
+// Create alternate representation in Julian calendar
+$julianDate = new DateInfo();
+$julianDate->setOriginal('3 September 1752');
+$julianDate->setFormal('+1752-09-03');
+$julianDate->setCalendar(CalendarType::JULIAN);
+
+// Link the alternate calendar date
+$gregorianDate->setAlternateCalendarDates([$julianDate]);
+
+// Now you have both representations
+echo "Gregorian: " . $gregorianDate->getOriginal() . "\n";
+echo "Julian: " . $gregorianDate->getAlternateCalendarDates()[0]->getOriginal() . "\n";
+```
+
+#### Example: Multiple Alternate Calendars
+
+```php
+setOriginal('1 January 2000');
+$primaryDate->setFormal('+2000-01-01');
+$primaryDate->setCalendar(CalendarType::GREGORIAN);
+
+// Julian equivalent
+$julianDate = new DateInfo();
+$julianDate->setOriginal('19 December 1999');
+$julianDate->setFormal('+1999-12-19');
+$julianDate->setCalendar(CalendarType::JULIAN);
+
+// Hebrew equivalent
+$hebrewDate = new DateInfo();
+$hebrewDate->setOriginal('23 Tevet 5760');
+$hebrewDate->setCalendar(CalendarType::HEBREW);
+
+// Hijri equivalent
+$hijriDate = new DateInfo();
+$hijriDate->setOriginal('24 Ramadan 1420');
+$hijriDate->setCalendar(CalendarType::HIJRI);
+
+// Add all alternate calendars
+$primaryDate->setAlternateCalendarDates([$julianDate, $hebrewDate, $hijriDate]);
+
+// Access alternate dates
+foreach ($primaryDate->getAlternateCalendarDates() as $altDate) {
+ echo $altDate->getCalendar() . ": " . $altDate->getOriginal() . "\n";
+}
+```
+
+#### Example: French Republican Calendar
+
+```php
+setOriginal('1 Vendémiaire An II');
+$frenchDate->setCalendar(CalendarType::FRENCH_REPUBLICAN);
+
+// Gregorian equivalent
+$gregorianDate = new DateInfo();
+$gregorianDate->setOriginal('22 September 1793');
+$gregorianDate->setFormal('+1793-09-22');
+$gregorianDate->setCalendar(CalendarType::GREGORIAN);
+
+$frenchDate->setAlternateCalendarDates([$gregorianDate]);
+```
+
+---
+
+## Date Confidence Levels
+
+Along with calendar support, you can now specify confidence levels for dates.
+
+**Namespace**: `Gedcomx\Types\ConfidenceLevel`
+
+### Available Confidence Levels
+
+```php
+setOriginal('15 May 1850');
+$birthDate->setFormal('+1850-05-15');
+$birthDate->setCalendar(CalendarType::GREGORIAN);
+$birthDate->setConfidence(ConfidenceLevel::HIGH);
+
+// Low confidence date (estimated from census)
+$deathDate = new DateInfo();
+$deathDate->setOriginal('About 1920');
+$deathDate->setFormal('+1920');
+$deathDate->setCalendar(CalendarType::GREGORIAN);
+$deathDate->setConfidence(ConfidenceLevel::LOW);
+```
+
+---
+
+## Complete Examples
+
+### Example 1: Complete Family with Enhanced Dates
+
+```php
+setId('JOHN-SMITH-1820');
+
+$fatherBirth = new Fact();
+$fatherBirth->setType('http://gedcomx.org/Birth');
+
+$fatherBirthDate = new DateInfo();
+$fatherBirthDate->setOriginal('10 January 1820');
+$fatherBirthDate->setFormal('+1820-01-10');
+$fatherBirthDate->setCalendar(CalendarType::GREGORIAN);
+$fatherBirthDate->setConfidence(ConfidenceLevel::HIGH);
+
+$fatherBirth->setDate($fatherBirthDate);
+$father->setFacts([$fatherBirth]);
+
+// Create mother
+$mother = new Person();
+$mother->setId('MARY-JONES-1825');
+
+// Create children
+$child1 = new Person();
+$child1->setId('JAMES-SMITH-1845');
+
+$child2 = new Person();
+$child2->setId('SARAH-SMITH-1847');
+
+// Create family view
+$family = new FamilyView();
+$family->setId('SMITH-FAMILY-1850');
+
+$fatherRef = new ResourceReference();
+$fatherRef->setResourceId($father->getId());
+$family->setParent1($fatherRef);
+
+$motherRef = new ResourceReference();
+$motherRef->setResourceId($mother->getId());
+$family->setParent2($motherRef);
+
+$child1Ref = new ResourceReference();
+$child1Ref->setResourceId($child1->getId());
+$family->addChild($child1Ref);
+
+$child2Ref = new ResourceReference();
+$child2Ref->setResourceId($child2->getId());
+$family->addChild($child2Ref);
+
+// Serialize to JSON
+$familyJson = json_encode($family->toArray(), JSON_PRETTY_PRINT);
+$fatherJson = json_encode($father->toArray(), JSON_PRETTY_PRINT);
+
+echo "Family:\n{$familyJson}\n\n";
+echo "Father:\n{$fatherJson}\n";
+```
+
+### Example 2: Historical Date with Calendar Conversion
+
+```php
+setOriginal('2 September 1752');
+$lastJulianDay->setFormal('+1752-09-02');
+$lastJulianDay->setCalendar(CalendarType::JULIAN);
+$lastJulianDay->setConfidence(ConfidenceLevel::HIGH);
+
+// This is also 13 September 1752 in Gregorian
+$gregorianEquiv = new DateInfo();
+$gregorianEquiv->setOriginal('13 September 1752');
+$gregorianEquiv->setFormal('+1752-09-13');
+$gregorianEquiv->setCalendar(CalendarType::GREGORIAN);
+
+$lastJulianDay->setAlternateCalendarDates([$gregorianEquiv]);
+
+// Serialize
+$json = json_encode($lastJulianDay->toArray(), JSON_PRETTY_PRINT);
+echo $json;
+```
+
+### Example 3: Jewish Genealogy with Hebrew Dates
+
+```php
+setId('ABRAHAM-COHEN-1850');
+
+// Birth with Hebrew date
+$birthFact = new Fact();
+$birthFact->setType('http://gedcomx.org/Birth');
+
+// Primary date in Hebrew calendar
+$hebrewBirthDate = new DateInfo();
+$hebrewBirthDate->setOriginal('15 Av 5610');
+$hebrewBirthDate->setCalendar(CalendarType::HEBREW);
+
+// Gregorian equivalent
+$gregorianBirthDate = new DateInfo();
+$gregorianBirthDate->setOriginal('August 6, 1850');
+$gregorianBirthDate->setFormal('+1850-08-06');
+$gregorianBirthDate->setCalendar(CalendarType::GREGORIAN);
+
+$hebrewBirthDate->setAlternateCalendarDates([$gregorianBirthDate]);
+
+$birthFact->setDate($hebrewBirthDate);
+
+$birthPlace = new PlaceReference();
+$birthPlace->setOriginal('Warsaw, Poland');
+$birthFact->setPlace($birthPlace);
+
+$person->setFacts([$birthFact]);
+```
+
+### Example 4: Multi-Generation Family Tree
+
+```php
+setId('GENERATION-1');
+
+$grandfather = new ResourceReference();
+$grandfather->setResource('GRANDFATHER-1800');
+$grandparentsFamily->setParent1($grandfather);
+
+$grandmother = new ResourceReference();
+$grandmother->setResource('GRANDMOTHER-1805');
+$grandparentsFamily->setParent2($grandmother);
+
+// Their child (who becomes parent in next generation)
+$parent = new ResourceReference();
+$parent->setResource('PARENT-1825');
+$grandparentsFamily->addChild($parent);
+
+// Parents' family
+$parentsFamily = new FamilyView();
+$parentsFamily->setId('GENERATION-2');
+$parentsFamily->setParent1($parent);
+
+$otherParent = new ResourceReference();
+$otherParent->setResource('OTHER-PARENT-1828');
+$parentsFamily->setParent2($otherParent);
+
+// Grandchildren
+for ($i = 1; $i <= 4; $i++) {
+ $child = new ResourceReference();
+ $child->setResource("CHILD-{$i}");
+ $parentsFamily->addChild($child);
+}
+
+// Now you have two generations of families
+$families = [$grandparentsFamily, $parentsFamily];
+```
+
+---
+
+## Migration Guide
+
+### Upgrading from Earlier Versions
+
+If you're upgrading from an earlier version of the SDK, here's what you need to know:
+
+#### 1. Existing DateInfo Objects
+
+**Before** (still works):
+```php
+$date = new DateInfo();
+$date->setOriginal('1900');
+$date->setFormal('+1900');
+```
+
+**After** (enhanced with new properties):
+```php
+$date = new DateInfo();
+$date->setOriginal('1900');
+$date->setFormal('+1900');
+$date->setCalendar(CalendarType::GREGORIAN); // NEW
+$date->setConfidence(ConfidenceLevel::HIGH); // NEW
+```
+
+✅ **Backward compatible**: Old code continues to work without changes.
+
+#### 2. Representing Families
+
+**Before** (using Relationship):
+```php
+use Gedcomx\Conclusion\Relationship;
+
+$relationship = new Relationship();
+$relationship->setType('http://gedcomx.org/ParentChild');
+$relationship->setPerson1($parentRef);
+$relationship->setPerson2($childRef);
+```
+
+**After** (using FamilyView for display):
+```php
+use Gedcomx\Conclusion\FamilyView;
+
+$family = new FamilyView();
+$family->setParent1($parentRef);
+$family->addChild($childRef);
+```
+
+✅ **Note**: Both approaches are valid. Use FamilyView for display, Relationship for formal conclusions.
+
+#### 3. JSON/XML Serialization
+
+✅ **Automatic**: All new properties serialize automatically using existing `toArray()` and `writeXmlContents()` methods.
+
+**Example**:
+```php
+$date = new DateInfo();
+$date->setOriginal('1900');
+$date->setCalendar(CalendarType::GREGORIAN);
+
+// Automatically includes calendar in output
+$json = json_encode($date->toArray());
+```
+
+---
+
+## Best Practices
+
+### Calendar Selection Guidelines
+
+1. **Use GREGORIAN** for:
+ - Modern dates (post-1582 in Catholic countries, post-1752 in Britain)
+ - Dates with no specific calendar context
+ - International genealogy
+
+2. **Use JULIAN** for:
+ - Pre-1582 dates in Catholic countries
+ - Pre-1752 dates in Britain and colonies
+ - Historical European research
+
+3. **Use HEBREW** for:
+ - Jewish religious dates
+ - Events recorded in Hebrew calendar
+ - Synagogue records
+
+4. **Use HIJRI** for:
+ - Islamic dates
+ - Events in Muslim-majority countries
+ - Mosque records
+
+5. **Use FRENCH_REPUBLICAN** for:
+ - Dates during French Revolution (1793-1805)
+ - French civil records from this period
+
+### When to Use Alternate Calendars
+
+✅ **Do use alternate calendars when:**
+- Original records use different calendars
+- Accuracy requires showing both representations
+- Calendar transitions occur during the time period
+- Research spans multiple calendar systems
+
+❌ **Don't use alternate calendars when:**
+- Only one calendar is relevant
+- No ambiguity exists
+- Overkill for the use case
+
+### FamilyView vs Relationship
+
+| Use Case | FamilyView | Relationship |
+|----------|-----------|--------------|
+| UI display of families | ✅ | ❌ |
+| Family tree visualization | ✅ | ❌ |
+| Pedigree charts | ✅ | ❌ |
+| Formal genealogical conclusions | ❌ | ✅ |
+| Recording relationship facts | ❌ | ✅ |
+| Source citations for relationships | ❌ | ✅ |
+| Evidence-based relationships | ❌ | ✅ |

+# Quick Start Guide - New Features
+
+Quick examples to get started with FamilyView and multi-calendar support in GEDCOM X PHP SDK v4.3.0.
+
+## FamilyView - 5 Minute Quickstart
+
+### Basic Family
+
+```php
+setId('my-family');
+
+// Add parents
+$father = new ResourceReference();
+$father->setResource('person-id-1');
+$family->setParent1($father);
+
+$mother = new ResourceReference();
+$mother->setResource('person-id-2');
+$family->setParent2($mother);
+
+// Add children
+$child = new ResourceReference();
+$child->setResource('person-id-3');
+$family->addChild($child);
+
+// Convert to JSON
+echo json_encode($family->toArray(), JSON_PRETTY_PRINT);
+```
+
+**Output:**
+```json
+{
+ "id": "my-family",
+ "parent1": {
+ "resource": "person-id-1"
+ },
+ "parent2": {
+ "resource": "person-id-2"
+ },
+ "children": [
+ {
+ "resource": "person-id-3"
+ }
+ ]
+}
+```
+
+## Calendar Support - 5 Minute Quickstart
+
+### Simple Calendar Usage
+
+```php
+setOriginal('25 December 1800');
+$date->setFormal('+1800-12-25');
+$date->setCalendar(CalendarType::GREGORIAN);
+$date->setConfidence(ConfidenceLevel::HIGH);
+
+echo $date->getCalendar(); // "http://gedcomx.org/Gregorian"
+```
+
+### Alternate Calendar Dates
+
+```php
+setOriginal('14 September 1752');
+$gregorian->setCalendar(CalendarType::GREGORIAN);
+
+// Alternate date (Julian)
+$julian = new DateInfo();
+$julian->setOriginal('3 September 1752');
+$julian->setCalendar(CalendarType::JULIAN);
+
+// Link them
+$gregorian->setAlternateCalendarDates([$julian]);
+
+// Serialize
+echo json_encode($gregorian->toArray(), JSON_PRETTY_PRINT);
+```
+
+**Output:**
+```json
+{
+ "original": "14 September 1752",
+ "calendar": "http://gedcomx.org/Gregorian",
+ "alternateCalendarDates": [
+ {
+ "original": "3 September 1752",
+ "calendar": "http://gedcomx.org/Julian"
+ }
+ ]
+}
+```
+
+## Available Calendar Types
+
+```php
+use Gedcomx\Types\CalendarType;
+
+CalendarType::GREGORIAN // Modern calendar (1582+)
+CalendarType::JULIAN // Pre-Gregorian European calendar
+CalendarType::HEBREW // Jewish calendar
+CalendarType::HIJRI // Islamic calendar
+CalendarType::FRENCH_REPUBLICAN // French Revolutionary calendar
+```
+
+## Available Confidence Levels
+
+```php
+use Gedcomx\Types\ConfidenceLevel;
+
+ConfidenceLevel::HIGH // High confidence (e.g., birth certificate)
+ConfidenceLevel::MEDIUM // Medium confidence (e.g., census record)
+ConfidenceLevel::LOW // Low confidence (e.g., estimated date)
+```
+
+## Complete Example: Person with Family
+
+```php
+setId('john-smith-1800');
+
+$birthFact = new Fact();
+$birthFact->setType('http://gedcomx.org/Birth');
+
+$birthDate = new DateInfo();
+$birthDate->setOriginal('10 January 1800');
+$birthDate->setFormal('+1800-01-10');
+$birthDate->setCalendar(CalendarType::GREGORIAN);
+$birthDate->setConfidence(ConfidenceLevel::HIGH);
+
+$birthFact->setDate($birthDate);
+$person->setFacts([$birthFact]);
+
+// Create family
+$family = new FamilyView();
+$family->setId('smith-family');
+
+$parentRef = new ResourceReference();
+$parentRef->setResourceId($person->getId());
+$family->setParent1($parentRef);
+
+echo "Person created with ID: " . $person->getId() . "\n";
+echo "Birth date calendar: " . $person->getFacts()[0]->getDate()->getCalendar() . "\n";
+echo "Family created with ID: " . $family->getId() . "\n";
+```
