ODM Version 1.3.1 has been designed to provide backward compatibility with previous versions of the model in most cases. In cases where backward compatibility has been impacted, it is due to clarifying the specification to more completely match the original intent of the standard.

The model includes the clinical data along with its associated metadata, administrative data, reference data and audit information. All of the information that needs to be shared among different software systems during the setup, operation, analysis, submission or for long term retention as part of an archive is included in the model.
