The implementation provides complete OpenAPI 3.1 specification compliance while maintaining 100% backward compatibility with OpenAPI 3.0. ## What Was Implemented ### 1. Schema Object Extensions (openapi3/schema.go) Added full JSON Schema 2020-12 support with new fields: - **`Const`** - Constant value validation - **`Examples`** - Array of examples (replaces singular `example`) - **`PrefixItems`** - Tuple validation for arrays - **`Contains`, `MinContains`, `MaxContains`** - Array containment validation - **`PatternProperties`** - Pattern-based property matching - **`DependentSchemas`** - Conditional schema dependencies - **`PropertyNames`** - Property name validation - **`UnevaluatedItems`, `UnevaluatedProperties`** - Unevaluated keyword support - **Type arrays** - Support for `["string", "null"]` notation ### 2. Document-Level Features (openapi3/openapi3.go) - **`Webhooks`** - New field for defining webhook callbacks (OpenAPI 3.1) - **`JSONSchemaDialect`** - Specifies default JSON Schema dialect - **Version detection methods**: - `IsOpenAPI3_0()` - Returns true for 3.0.x documents - `IsOpenAPI3_1()` - Returns true for 3.1.x documents - `Version()` - Returns major.minor version string ### 3. License Object (openapi3/license.go) - **`Identifier`** - SPDX license expression (alternative to URL) ### 4. Info Object (openapi3/info.go) - **`Summary`** - Short summary of the API (OpenAPI 3.1) ### 5. Types Helper Methods (openapi3/schema.go) New methods for working with type arrays: - `IncludesNull()` - Checks if null type is included - `IsMultiple()` - Detects type arrays (OpenAPI 3.1 feature) - `IsSingle()` - Checks for single type - `IsEmpty()` - Checks for unspecified types ### 6. JSON Schema 2020-12 Validator (openapi3/schema_jsonschema_validator.go) A new opt-in validator using [santhosh-tekuri/jsonschema/v6](https://github.com/santhosh-tekuri/jsonschema): - Full JSON Schema Draft 2020-12 compliance - Automatic OpenAPI → JSON Schema transformation - Converts OpenAPI 3.0 `nullable` to type arrays - Handles `exclusiveMinimum`/`exclusiveMaximum` conversion - Comprehensive error formatting - Fallback to built-in validator on compilation errors
…d formatting and correcting the version logic
The ResolveRefsIn function was not resolving $ref references inside webhooks, causing Schema.Value to be nil when a webhook operation referenced a component schema. This adds webhook ref resolution after the paths loop, using the same resolvePathItemRef function since webhooks contain PathItem objects. Co-Authored-By: Claude Opus 4.5 <noreply@anthropic.com>
In OpenAPI 3.0 (JSON Schema draft-04), exclusiveMinimum/exclusiveMaximum are booleans that modify minimum/maximum values. In OpenAPI 3.1 (JSON Schema 2020-12), they are numbers representing the actual exclusive bounds. This change introduces ExclusiveBound type that can hold either: - Bool: for OpenAPI 3.0 style boolean modifier - Value: for OpenAPI 3.1 style numeric bound The validation and marshaling logic handles both formats correctly.

The built-in validator did not enforce the JSON Schema const keyword, allowing any value to pass when only const was set. This adds visitConstOperation to reject values that don't match the const value, and updates IsEmpty() to treat schemas with const set as non-empty.
