Assumed value was a slick idea at the time, but I do agree with your sentiments now:
* it is hardly or not at all processable, * where there is widespread consensus on something it may well be assumed automatically by clinicians – but this is not because someone put the assumed value in the archetype or not. * Elements where such consensus exists across professions/sectors are probably rare anyway and universal consensus on an assumption is hard to ascertain * challenges for UI * challenges for querying (assuming you even dare) * challenges for anybody to understand it, including the difference to a default value (and what happens if there is both). Not sure about the implications for dropping/deprecating this at this stage Sebastian Von: openEHR-technical <openehr-technical-boun...@lists.openehr.org> Im Auftrag von Ian McNicoll Gesendet: Montag, 8.

I have come round to thinking that Assumed value is actually unhelpful. It is only a statement on the archetype and never ends up in the data, and completely non-processable. I think it can be easily misunderstood and is often very difficult to assert reliably. I would not be unhappy it see it dropped. We will however definitely need default values in specialisations e.g the lab series.
