The openEHR ITS-REST EHR API as implemented and published by Cadasto: create and read EHRs, read and update EHR_STATUS, commit/retrieve/update/logically-delete versioned COMPOSITIONs, manage the DIRECTORY (folder) structure, create and read CONTRIBUTIONs for atomic multi-object commits, and read/write ITEM_TAGs. 33 operations. Updates use RFC 7232 If-Match optimistic concurrency; deletes are logical and preserve version history for audit.
