Hi Frank
Thank you for your question.
We are working on a sample app to showcase some of the available capabilities in the Case Management framework. We expect to have this application public available in this quarter.
Meanwhile take a look here where you can find an overview of the Case Management framework architecture, available APIs, and some HOWTOs on how to start a case management type of application using the CMf and how to implement some of the common patterns.
My best regards
Solange
