The Center for eIntegrated Care (CeIC) in Dublin City University is a research center with a mission to advance eIntegrated care in order to improve citi- zen health and wellbeing. The core objective of the CeIC is to inform, develop and advance knowledge on integrated care at the national and international level to sup- port eHealth practices, empower citizens and practitioners. This chapter will provide a summary overview using a case study focused on development of an ontology underpinned by a published International Standard ISO 13940 entitled Health Infor- matics Systems of Concepts for Continuity of Care (Contsys). The development work focuses on semantic interoperabilty to support service improvement initiatives to in- form the development of core infrastructure for shared intellectual disablities care services. Based on user defined and agreed needs, the authors illustrate phase one of preliminary development work using a dedicated application to support COVID-19 clients in residential care units. This initial work is used to test an emerging con- ceptual framework underpinned by state of the art health informatics standards for knowledge discovery and data integration systems. Involving a scholarship group of intellectual disability service staff and users, a co-participatory design approach has been used to conduct the following methodology.
