title: Development of clinical contents model markup language for electronic health records.
abstract: OBJECTIVE
  To develop dedicated markup language for clinical contents models (CCM) to facilitate the active use of CCM in electronic health record systems.
  
  
  METHODS
  Based on analysis of the structure and characteristics of CCM in the clinical domain, we designed extensible markup language (XML) based CCM markup language (CCML) schema manually.
  
  
  RESULTS
  CCML faithfully reflects CCM in both the syntactic and semantic aspects. As this language is based on XML, it can be expressed and processed in computer systems and can be used in a technology-neutral way.
  
  
  CONCLUSIONS
  CCML HAS THE FOLLOWING STRENGTHS: it is machine-readable and highly human-readable, it does not require a dedicated parser, and it can be applied for existing electronic health record systems.
