  text: Data dictionaries provide structural meta-information about data definitions
    in health information technology (HIT) systems. In this regard, reusing healthcare
    data for secondary purposes offers several advantages (e.g. reduce documentation
    times or increased data quality). Prerequisites for data reuse are its quality,
    availability and identical meaning of data. In diverse projects, research data
    warehouses serve as core components between heterogeneous clinical databases and
    various research applications. Given the complexity (high number of data elements)
    and dynamics (regular updates) of electronic health record (EHR) data structures,
    we propose a clinical metadata warehouse (CMDW) based on a metadata registry standard.
    Metadata of two large hospitals were automatically inserted into two CMDWs containing
    16,230 forms and 310,519 data elements. Automatic updates of metadata are possible
    as well as semantic annotations. A CMDW allows metadata discovery, data quality
    assessment and similarity analyses. Common data models for distributed research
    networks can be established based on similarity analyses.
