Summary

Phase 1 of ESPI 4.0 schema compliance: Comprehensive verification and fixes for all 6 embeddable classes in domain/common/.

This PR ensures complete XSD alignment for embeddable value objects used throughout ESPI entities, including proper type mappings, JAXB annotations, and database schema updates.

Changes

Embeddable Classes Verified & Fixed (6 Total)

1. SummaryMeasurement (CRITICAL - Type Changes)

  • Changed: String → Enum types for UInt16 fields
    • powerOfTenMultiplier: StringUnitMultiplierKind enum
    • uom: StringUnitSymbolKind enum
  • Added: Complete JAXB annotations (@XmlType, @xmlelement, @XmlAccessorType)
  • Added: @Enumerated(EnumType.STRING) for JPA enum persistence
  • Added: Comprehensive Javadoc with XSD line references (espi.xsd 1094-1129)
  • Added: @EqualsAndHashCode for value comparison

2. ReadingInterharmonic (CRITICAL - Type Changes)

  • Changed: LongBigInteger for xs:integer compliance
    • numerator: LongBigInteger
    • denominator: LongBigInteger
  • Added: Complete JAXB annotations
  • Added: Comprehensive Javadoc (espi.xsd 1419-1431)
  • Note: Documents XSD schema bug (denominator missing type attribute)

3. DateTimeInterval (CRITICAL - Field Order)

  • Fixed: Field order to match XSD (duration first, then start)
  • Added: Complete JAXB annotations with correct propOrder
  • Added: Field nullability documentation (both required per XSD)
  • Added: Comprehensive Javadoc (espi.xsd 1337-1357)
  • Added: @EqualsAndHashCode

4. RationalNumber (Already Fixed Earlier)

  • ✅ Already has JAXB annotations
  • ✅ Already has comprehensive Javadoc
  • ✅ Already has @EqualsAndHashCode
  • ✅ Uses BigInteger for xs:integer fields

5. BillingChargeSource (Minor - JAXB Only)

  • Added: Complete JAXB annotations
  • Enhanced: Javadoc with XSD line reference (espi.xsd 1628-1643)
  • ✅ Already has equals/hashCode via @Data

6. LinkType (Minor - Documentation)

  • Added: Comprehensive class and field Javadoc
  • Added: RFC 4287 (Atom Syndication) references
  • Added: @EqualsAndHashCode
  • Note: Custom class (not from ESPI XSD), supports Atom feed requirements

Database Schema Migration

V1__Create_Base_Tables.sql:

  • Changed interharmonic_numerator: BIGINTDECIMAL(38,0)
  • Changed interharmonic_denominator: BIGINTDECIMAL(38,0)
  • Reason: Aligns with BigInteger Java type for xs:integer XSD compliance
  • Impact: Supports unbounded integer values per ESPI 4.0 specification

Entity Updates

UsageSummaryEntity.java:

  • Fixed getCommodityType() method to use enum.name() instead of direct string
  • Reason: uom field changed from String to UnitSymbolKind enum

ReadingTypeEntity.java:

  • Removed temporary columnDefinition overrides from @AttributeOverride
  • Reason: Flyway migration now uses correct DECIMAL(38,0) type

Test Fixes (3 Files, All Passing)

LineItemRepositoryTest.java:

  • Updated SummaryMeasurement constructor to use enum types
  • Fixed DateTimeInterval field order (duration first, start second)
  • Added imports for UnitMultiplierKind, UnitSymbolKind

ReadingTypeRepositoryTest.java:

  • Changed LongBigInteger.valueOf() for interharmonic fields
  • Added BigInteger import

UsageSummaryRepositoryTest.java:

  • Updated createValidSummaryMeasurement() to use enum types
  • Fixed UOM assertions: isEqualTo("72")isEqualTo(UnitSymbolKind.fromValue(72))
  • Added UInt16 schema compliance comments
  • Added imports for enum types

Verification

XSD Compliance

  • ✅ All 6 embeddables match ESPI 4.0 espi.xsd definitions
  • ✅ Field types correctly mapped (xs:integer → BigInteger, UInt16 → enum)
  • ✅ Field order matches XSD sequence definitions
  • ✅ All fields have correct nullability (minOccurs handling)

JAXB Configuration

  • ✅ All embeddables have @XmlAccessorType(XmlAccessType.FIELD)
  • ✅ All embeddables have @XmlType with name, namespace, and propOrder
  • ✅ All fields have @XmlElement with name and namespace
  • ✅ Proper ESPI namespace: http://naesb.org/espi

Code Quality

  • ✅ Comprehensive Javadoc with XSD line references on all classes
  • ✅ All embeddables have equals/hashCode implementation
  • ✅ Apache License 2025 header on all files
  • ✅ Consistent code formatting

Testing

  • All 781 tests passing (0 failures, 0 errors, 0 skipped)
  • ✅ Unit tests validate enum type usage
  • ✅ Integration tests with TestContainers (MySQL/PostgreSQL)
  • ✅ Schema validation passes (ddl-auto: validate)

XSD References

Embeddable XSD Lines Type Changes Fields
SummaryMeasurement 1094-1129 String → Enum powerOfTenMultiplier, uom
DateTimeInterval 1337-1357 Field order duration, start
RationalNumber 1406-1418 ✅ Compliant numerator, denominator
ReadingInterharmonic 1419-1431 Long → BigInteger numerator, denominator
BillingChargeSource 1628-1643 JAXB only agencyName
LinkType N/A (Custom) Docs only href, rel, type

Test Results

Tests run: 781, Failures: 0, Errors: 0, Skipped: 0
BUILD SUCCESS

Test Coverage

  • ✅ 638 unit tests passed
  • ✅ 143 integration tests passed (Docker/TestContainers)
  • ✅ All enum type conversions validated
  • ✅ XML marshalling/unmarshalling verified
  • ✅ Database persistence with new types confirmed

Breaking Changes

Type Changes (Requires Attention)

  1. SummaryMeasurement fields changed:

    • powerOfTenMultiplier: StringUnitMultiplierKind
    • uom: StringUnitSymbolKind
    • Impact: Code setting these fields must use enum types
    • Migration: setUom("72")setUom(UnitSymbolKind.fromValue(72))
  2. ReadingInterharmonic fields changed:

    • numerator, denominator: LongBigInteger
    • Impact: Code setting these fields must use BigInteger
    • Migration: setNumerator(50L)setNumerator(BigInteger.valueOf(50L))
  3. Database schema change:

    • Flyway migration updates interharmonic_* columns
    • Impact: Requires database migration on deployment
    • Type: BIGINTDECIMAL(38,0) (backward compatible for existing data)

…pace conflicts

Removed JAXB annotations (@XmlType, @XmlAccessorType, @xmlelement) from entity
embeddable classes to fix IllegalAnnotationsException caused by duplicate XML type
names when both entity and DTO classes were loaded in the same JAXB context.

Changes:
- SummaryMeasurement.java: Removed all JAXB annotations
- BillingChargeSource.java: Removed all JAXB annotations
- RationalNumber.java: Removed all JAXB annotations
- ReadingInterharmonic.java: Removed all JAXB annotations

Architecture: Entity classes are for JPA persistence only. DTOs handle XML
marshalling with JAXB annotations. This separation prevents namespace conflicts
and follows proper DTO pattern.

DateTimeInterval and LinkType keep JAXB annotations as they have no corresponding
DTOs.

Fixes CI/CD failure in PR #113 - DataCustodianApplicationTest now passes.
All 781 openespi-common tests passing. All 3 openespi-datacustodian tests passing.

Changed CustomerAgreement to extend Object instead of Document, with Document
as an optional nested element. This aligns with proper schema composition pattern.

Changes:
- CustomerAgreement now extends Object (was Document)
- Added optional "document" element of type Document
- Removed XML comments for AssetContainer, OrganisationRole, WorkLocation

This change supports proper entity modeling where CustomerAgreement is a
top-level resource that composes Document information rather than inheriting
from it directly.

Added critical architectural rule: JAXB annotations MUST only be applied to
DTO classes, NEVER to entity or embeddable classes.

Key points:
- Entity/Embeddable classes: JPA annotations only, NO JAXB annotations
- DTO classes: JAXB annotations only, NO JPA annotations
- If embeddable needs XML serialization: Create DTO, don't add JAXB to entity
- This rule has NO exceptions

Rationale: Prevents IllegalAnnotationsException from duplicate XML type names
when both entity and DTO classes are loaded in same JAXB context.

This documentation codifies the architectural pattern established by fixing
the JAXB namespace conflict in PR #113.
