this looks like a bit of a bag of worms... wondering if there is a plan...
Bryn Rhodes (Jun 28 2016 at 15:43):
So, the specification says that the minimum you must do is _respect_ quantities, so that's the first step.
Bryn Rhodes (Jun 28 2016 at 15:44):
Ideally, there would be some open source library that could be leveraged to support unit calculation. I know the FHIR reference implementations have some of that too (at least the .NET one has something along those lines), but I haven't looked into it enough yet to make a specific recommendation.

@Bryn Rhodes - catching up with old stuff there - the Java reference implementation inclues a full tested UCUM conversion suite
Erich Schulz (Jul 10 2016 at 22:55):
cool, @Grahame Grieve how does that cope with conversions dependant on the observation? (eg mM to mEq, IU to mg etc)
Grahame Grieve (Jul 11 2016 at 00:09):
as far as I know, there's no table containing the molecular weight of the analyte to the LOINC code - and activity there isn't even a single value
Erich Schulz (Jul 11 2016 at 02:39):
yeah - i'm just seeing this as a bit of a can of worms...
Bryn Rhodes (Jul 24 2017 at 07:53):
@Grahame Grieve, resurrecting this issue, are you talking about the HAPI FHIR Server reference implementation? I went looking for this the other day and all I could find was a call to a UCUM conversion service, which appears to be the one you host, is that right?
Grahame Grieve (Jul 24 2017 at 08:01):
see the package org.hl7.fhir.utilities.ucum in the build tools
Bryn Rhodes (Jul 24 2017 at 15:03):
Thanks Grahame! Is the service here (http://hl7connect.healthintersections.com.au/svc/ucum?format=text/html) still up? I keep getting timeouts trying to hit it.
Grahame Grieve (Jul 24 2017 at 15:33):
don't know. probably not
