Abstract
This paper reports on the design and development of an infrastructure allowing one to share and exchange multimedia data in the context of a health network. A single technology exploiting a semantic model of the hospital universe provides users with information and data of diverse origins, generated by the various actors or departments of the health organization. Functions provided include act management and patient record management governed by domain semantics. The functionality has been validated through laboratory experiments against the requirements of protocol directed care and health networks. The functionality is integrated into a clinician workstation exploited in the Internet/Intranet environment thanks to a commercial browser. These results have been obtained with the support of several projects in the frame of the Health-Care Telematics Applications Programme of the European Community and of the Eureka Programme.
