title: Educational challenge of health information systems' interoperability.
abstract: OBJECTIVE
  As health care develops from an organization-centered via service-centered (disease management) towards a person-centered system (favored homecare, patient monitoring, body area networks), information systems involved have to be semantically interoperable, process-related, decision-supportive, context-sensitive, user-oriented, and trustworthy.
  
  
  METHODS
  The aforementioned paradigm shift requires highly flexible solutions based on knowledge concepts, provided by a service-oriented and model-driven approach.
  
  
  RESULTS
  Information systems' design, implementation and maintenance have to be realized based on formal grammar. This is true for all considered aspects and views of the system and its components, using metalanguages and reflecting all domains touched.
  
  
  CONCLUSIONS
  For meeting the challenge, involvement of, and close collaboration between, experts from different domains as well as knowledge and tooling regarding formal modeling and model interchange are required.
