title: Designing and implementing health data and information providers.
abstract: OBJECTIVE
  To model and implement web portals providing access to certified and high-quality information in the domain of health.
  
  
  METHODS
  The Unified Medical Language System (UMLS) knowledge sources of the U.S. National Library of Medicine and principles of implementation resulting from the previous ARIANE project are described. The XML technology that allows files transformations by the means of XSLT is briefly presented.
  
  
  RESULTS
  The design and implementation of software modules that exploit knowledge sources, operate the translation of a user's query to selected information sources, and wrap obtained results are detailed. Querying documentary and factual medical databases are presented.
  
  
  CONCLUSIONS
  Current implementation and wrapping perspectives are discussed in terms of integration and interoperability of health information and data resources.
