However, there are a couple of factors like sensitivity of the information or the difficulties of cross-sector communication hindering an effective information exchange. Therefore, it is suggested to develop a standardised language for the purpose of cross-sector information exchange that takes these factors into account. The paper presents some concepts for such an information exchange and sketches a Risk Management Language (RML) that could be used for this purpose.encritical infrastructurecross-sector communicationRisk Management Language (RML)005400conference paper
