Unknown keyword openapi when creating a schema of an openAPI 3.0 file #1205
Description
Im trying to validate a json playload against a schema defined in a openAPI 3.0 file.
I was following this: https://github.com/networknt/json-schema-validator/blob/1.5.9/doc/openapi.md
When i do this and create a JsonSchema for my file i get a few "unknown keyword" warnings:
2025-10-24 12:07:40,920 WARN [main] com.networknt.schema.UnknownKeywordFactory:37 Unknown keyword openapi - you should define your own Meta Schema. If the keyword is irrelevant for validation, just use a NonValidationKeyword or if it should generate annotations AnnotationKeyword 2025-10-24 12:07:40,929 WARN [main] com.networknt.schema.UnknownKeywordFactory:37 Unknown keyword info - you should define your own Meta Schema.

If the keyword is irrelevant for validation, just use a NonValidationKeyword or if it should generate annotations AnnotationKeyword I would like to fix those warnings to keep my log clean if possible.
I also tried loading a 3.0 meta schema from the class path like this:
JsonSchemaFactory factory = JsonSchemaFactory.getInstance(SpecVersion.VersionFlag.V4, builder -> builder .defaultMetaSchemaIri("classpath:oas/3.0/schema/2024-10-18") .metaSchema(JsonMetaSchema.builder("classpath:oas/3.0/schema/2024-10-18").build())); JsonSchema baseSchema = factory.getSchema(SchemaLocation.of("classpath:openapi.yaml")); but that also now gives the "items" keyword as unknwon.
I dont really know what im doing wrong or what i need to do to fix this.
