EHR versioning. Example EHR changes to VERSIONED_OBJECTs over time, committed and logged as contributions at four separate time points (the time axis goes downwards). COMPOSITIONs, FOLDER, EHR_ACCESS, and EHR_STATUS are all versioned using the same mechanism. Compositions can be flagged as being of type ‘event’ (blue above) intended for one-time recordings, or flagged as ‘persistent’ (green above) intended for long time continuously updated use. Abbreviated example identifiers are illustrated under the shapes. The figure was inspired by Figure 8 in the openEHR architecture overview document[5].
