MDG Technology for CMMN

The MDG Technology for the Case Management Model & Notation (CMMN) allows you to create CMMN models with Enterprise Architect.

"A Case is a proceeding that involves actions taken regarding a subject in a particular situation to achieve a desired outcome. Traditional examples come from the legal and medical worlds, where a legal Case involves the application of the law to a subject in a certain fact situation, and a medical Case involves the care of a patient in the context of a medical history and current medical problems."

(Quoted from the Object Management Group (OMG) Case Management Model and Notation Specification (Version 1.0, May 2014))
