Modello

Modello is a framework for code generation from a simple model. Modello generates code from a simple model format: based on a plugin architecture, various types of code and descriptors can be generated from the single model, including Java POJOs, XML/JSON/YAML marshallers/unmarshallers, XSD, JSON Schema and documentation. Starting with 2.1.0, content can even be generated from Velocity templates for maximum flexibility.
