The care networks of community-dwelling older adults require cooperation between different actors, including health and social caregivers, assistant providers, care receivers, and their informal caregivers (e.g. relatives or friends), across time, space, and organizational boundaries. In this context, the project Social Cooperation for Integrated Assisted Living (SOCIAL) aims at the development of a platform of services to support the care networks of community-dwelling older adults. Therefore, the study reported in this article assess the adequacy of the Fast Healthcare Interoperability Resources (FHIR) to guarantee the interoperability of the relevant information related to the assisted persons of the SOCIAL platform, which are mainly older adults that need care and assistance services.
