Planning: MOXy JSON Schema Generation
Currently EclipseLink supports generating XML Schemas from a JAXBContext. A feature will be added to generate JSON Schemas. At first this feature will be based on JAXB metadata and mappings, in the future this will be adapted to JSON-B metadata.
The development of this feature will need to be split into multiple phases. The current EclipseLink JSON support is insufficient to map to a json schema document. Additional enhancements will be required in order to generate these schemas.
