Welcome to Apache Isis Apache Isis is a full-stack open source application development framework, designed to let you rapidly develop domain-driven business enterprise applications. The framework is designed around two patterns: * the first is the naked objects pattern, whereby the framework automatically generates an object-oriented user interface (OOUI) for your domain objects. If required, this OOUI can then be customized. * the second is the hexagonal architecture. This means it allows the same domain model to be run with different viewers, either as a desktop app or as a webapp. Equally, you can choose which object store to use in order to persist your domain objects. The diagram below shows the hexagonal architecture as it is implemented by Apache Isis.
