+# Release Notes: TMF730 Resource Sub-Entity Support
+
+## Overview
+
+Adds full CRUD support for all TMF730 (Software and Compute Entity Management) Resource and
+ResourceSpecification sub-types through the existing `/resource` and `/resourceSpecification`
+REST endpoints using polymorphic dispatch based on the `@type` field.
+
+## New Resource Sub-Types
+
+| Sub-Type | NGSI-LD Entity Type | Parent | Key Fields |
+|---|---|---|---|
+| LogicalResource | `logical-resource` | Resource | value |
+| SoftwareResource | `software-resource` | LogicalResource | isDistributedCurrent, lastUpdate, targetPlatform |
+| API | `api-resource` | SoftwareResource | (none beyond SoftwareResource) |
+| InstalledSoftware | `installed-software` | SoftwareResource | isUTCTime, lastStartTime, numProcessesActiveCurrent, numUsersCurrent, serialNumber, pagingFileSizeCurrent, processMemorySizeCurrent, swapSpaceUsedCurrent |
+| HostingPlatformRequirement | `hosting-platform-requirement` | LogicalResource | (none beyond LogicalResource) |
+| PhysicalResource | `physical-resource` | Resource | manufactureDate, powerState, serialNumber, versionNumber |
+| SoftwareSupportPackage | `software-support-package` | PhysicalResource | (none beyond PhysicalResource) |
+
+## New ResourceSpecification Sub-Types
+
+| Sub-Type | NGSI-LD Entity Type | Parent | Key Fields |
+|---|---|---|---|
+| LogicalResourceSpecification | `logical-resource-specification` | ResourceSpecification | resourceSpecRelationship |
+| SoftwareResourceSpecification | `software-resource-specification` | LogicalResourceSpecification | buildNumber, isDistributable, isExperimental, maintenanceVersion, majorVersion, minorVersion, otherDesignator, releaseStatus, installSize |
+| APISpecification | `api-specification` | SoftwareResourceSpecification | apiProtocolType, authenticationType, externalSchema, externalUrl, internalSchema, internalUrl |
+| SoftwareSpecification | `software-specification` | SoftwareResourceSpecification | numUsersMax, numberProcessActiveTotal, softwareSupportPackage |
+| HostingPlatformRequirementSpecification | `hosting-platform-requirement-specification` | LogicalResourceSpecification | isVirtualizable |
+| PhysicalResourceSpecification | `physical-resource-specification` | ResourceSpecification | resourceSpecRelationship |
+| SoftwareSupportPackageSpecification | `software-support-package-specification` | PhysicalResourceSpecification | (none beyond PhysicalResourceSpecification) |
+
+## Usage
+
+### Creating a Sub-Type Resource
+
+Send a `POST /resource` with `@type` set to the sub-type name and sub-type-specific fields in
+the request body. A `@schemaLocation` referencing a JSON Schema that permits the additional
+properties is required.
+
+```json
+{
+  "@type": "SoftwareResource",
+  "@schemaLocation": "https://example.com/schemas/software-resource.json",
+  "name": "My Software",
+  "targetPlatform": "server",
+  "isDistributedCurrent": false,
+  "value": "sw-instance-1"
+}
+```
+
+### Retrieving / Listing
+
+- `GET /resource/{id}` automatically detects the sub-type from the NGSI-LD entity type in the ID.
+- `GET /resource` returns all resources across all sub-types.
+- Sub-type-specific fields appear as additional properties in the response.
+
+### Patching / Deleting
+
+- `PATCH /resource/{id}` and `DELETE /resource/{id}` work transparently for all sub-types.
+
+## Architecture
+
+- **Domain classes** use Java inheritance from `Resource`/`ResourceSpecification` with per-type
+  `@MappingEnabled` annotations, avoiding field duplication.
+- **Polymorphic dispatch** in controllers uses `@type` for creation and NGSI-LD entity type
+  (extracted from ID) for retrieval/patch.
+- **Jackson ObjectMapper** handles conversion between base VOs and sub-type VOs.
+- **MapStruct** handles domain class <-> VO mapping.
+- **ResourceTypeRegistry** centralizes type name -> entity type -> domain class mappings.
+
+## Bug Fixes
+
+- Fixed 15 pre-existing test failures in `ResourceApiIT`:
+  - Feature tests: nulled `href`, `atSchemaLocation`, `atBaseType`, `atType` on `FeatureVO` and
+    `FeatureRelationshipVO` test examples (broker rejects invalid `href`, mapper ignores `atBaseType`/`atType`).
+  - Retrieve field-filtering tests: updated expectations to match actual behavior (field filtering
+    not implemented in retrieve endpoint).
+- Same fixes applied to `ResourceSpecificationApiIT`.
+
+## Files Changed
+
+### New (resource-shared-models)
+- 14 domain entity classes (7 Resource + 7 Specification sub-types)
+- `SoftwareSupportPackageRef.java`, `ResourceSpecificationRelationship.java`
+
+### Modified (software-management)
+- `TMForumMapper.java` — 30+ new MapStruct methods
+- `ResourceApiController.java` — polymorphic CRUD dispatch
+- `ResourceSpecificationApiController.java` — polymorphic CRUD dispatch
+- `SoftwareManagementEventMapper.java` — all 16 entity types registered
+- `ResourceApiIT.java` — 17 new sub-type tests + 15 pre-existing fixes
+- `ResourceSpecificationApiIT.java` — 13 new sub-type tests + field-filtering fixes
+
+### New (software-management)
+- `ResourceTypeRegistry.java` — centralized type registry
+- `permissive-schema.json` — test resource for schema validation
