ISO 21090 is a true ISO standard. It does include a lot of OpenEHR data type specs, except where OpenEHR decided to go their own way.
And in the HL7 space some are working on implementing the ISO 21090 standard in the HL7 models, which is quite a task, not impossible, but a lot of work. ISO 21090 is based on HL7 input yes, but it is definitely not an HL7 standard. In particular the Coded Ordinal as in ISO 21090 meets the clinical and research requirement of allowing both computations and code and display text use for the semantics. That is not present in most HL7 v3 standards and will cause some upgrading of most messages. It (ISO 21090) could have been "more" an OpenEHR standard if OpenEHR had more cooperated in this space instead of reinventing again their own data types.
