Hi Daniel
No one is talking about abandoning what we have. The only question is about the
way that the casual measurements of countable discrete things where the ucum
unit is 1 are handled. I think that we're agreed that openEHR and, for that
matter, HL7 v2 and v3 haven't go this right yet. In
But the question around can you trust the data is, can you recognize properly
when the units are ucum or not? For some reason I haven't put my finger on, you
are linking the knowing of this with the boundary of the type. It's not clear
to me why you're making that link.

you prohibit people from making observations or measurements that

why?
HL7 does because we claim that you have to have UCUM codes

well it's not prevented from being expressed; it's just expressed using a
Quantity field (e.g. a DV_COUNT) and another field saying what you are
counting (there are a reasonable number of examples of this already in the
archetypes - number of cigarettes a day, number of previous pregnancies,

As Grahame mentioned on an earlier post, the question of units is thorny.
Although we technical people would like to mandate UCUM or some other
well-designed computable syntax, on its own, it won't work. There seem
this triggers further thoughts.

ok, so you say it should be computable, but then allow a fixed unit of one,

could always use it or encounter it in place of quantity. So if that's the

you'll still have to look, even though it's not many cases.

Hi Thomas,
I had an issue recently were I was receiving HL7 V2 Lab messages with
units such as x10^6/L, the equivalent in UCUM is 10*6/l, which was
used in the archetype constraint for an RBC element. I translated the
HL7 unit into the archetype

Graham,
I'm trying to make sense of this discussion around computability -- what
are the kinds of things that one wants to compute with these kinds of
countable things?

Ok ... can't resist replying ...
Doesn't 'computability' depend on having clearly defined rules on how the UOMs
relate to each other? Yes, UCUM provides this - however I don't understand why
