 # Current state of development
 Most components are under active development. In 2016 the whole product has been migrated from the technical structured OSGi architecture
 towards a business oriented architecture with Spring Boot microservices and Netflix OSS components. Documentation of previously released

 Framework and this is still fine, and the right choice. Spring in combination with OSGi seemed to be the perfect match to build a modular
 and extensible base project. Unfortunately Spring stopped their efforts on OSGi, in particular on Spring dmServer and Spring Dynamic Modules
 . In a transition step to the current microservice architecture, we put all the OSGi bundles into a fat JavaEE WAR deployment unit to run
 the application on a servlet container like Apache Tomcat. After that we redesigned all services and business functions and applied a
