title: Mediation services with health information sources.
abstract: OBJECTIVE
  To design and implement mediators dedicated to access various kinds of information sources in the framework of the project ARIANE.
  
  
  METHODS
  Mediators are dynamically built thanks to three components: pieces of knowledge issued from the UMLS knowledge sources and from a catalog of information sources, processes that translate a query into the syntax of a target source, and communication services provided by operating systems.
  
  
  RESULTS
  A scenario details the complete mediation process with an indexed web site.
  
  
  CONCLUSIONS
  This approach mixes knowledge and software engineering. It benefits from services provided by operating systems and allows scalability and reusability of software components.
