Common Data Elements (CDEs) are standardised, precisely defined question paired with specific allowable responses. These CDEs can be used systematically across different sites, studies, or clinical trials to ensure consistent data collection [NIH]. These CDEs can be annotated with an ontological model to define their meaning and facilitate integration of CDEs from different registries [de novoDe Novo]. The ontological model is essential for computers to assess that common data elements are indeed common [de novoDe Novo].
By publishing the CDEs and the ontologies to annotate them openly, they can be reused to build case report forms for data collection [de novoDe Novo].
