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.
Phases
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.
Phase 1: Additional Mapping Support
JSON Schemas in several places specify collections of data where the name of the element corresponds to a property in the object. This is something that is not currently supported by eclipselink's oxm/json binding layer. This would require adding support
Example:
Mapping the list of properties on a schema. The name of the property is the key (or element) in the json schema, so this would require a variable-path mapping of some sort:
{ ... {"properties": { "firstName":{"type":"string"}, "lastName":{"type":"string"} } }
Would need to be mapped to:
public class Schema { ... List<Property> properties; }
public class Property { String name; String type; }
Where name maps to the key/element name of the property entry.
