HL7 is a standard developed to support the exchange of information related to the medical field across institutions from the same country or from different countries. This standard provides mainly a framework to sustain the data exchange at the application / technical layer and the thereby minimize the importance of business / organization information. This is contradictory to the arising requirements dictated by the information security governance which claims the access rights to be only provided where there are business justifications. In this context, the paper aims at extending HL7 with a responsibility perspective in order to enhance the access rights considering organization constraints. Therefore, the paper firstly proposes an integration of both models and secondly provides an innovative HL7 XML format which supports new business related information framework defined around the notion of responsibility.
