Résumé
Several research work and initiatives have been proposed in the literature to identify the dimensions of interoperability and to define a framework that provides organizing mechanism and knowledge of this field in a structured way. However, the lack of a common understanding and a consensus on these dimensions is one of the biggest barriers to true interoperability. In this paper, we aim to identify the required dimensions that have to be taken into account to facilitate interoperability between health systems by (i) a survey of the main research works and initiatives dealing with interoperability in the health domain and (ii) the investigation of a comparative analysis of the interoperability reference frameworks based on specified criteria.
