Stream: R4A/B/R5 Discussion
Topic: Timings
Rik Smithies (Jul 30 2020 at 20:26):
I would like to see brief rationales for the times taken.
e.g. 4A - Increased wait to a release that actually makes key clinical stuff normative - gets pushed back by at least a year, probably longer.
What is going to cause more than a year's delay?
Is it ballots, that absolutely have to take 2 or 3 cycles (a lot of elapsed time but maybe not a full year's solid effort - and perhaps could be done in parallel with other things).
Or is it processes that could in theory be accelerated with more resources, better systems etc.
Lloyd McKenzie (Jul 30 2020 at 20:30):
We can't reasonably ballot in parallel. We can't have two different releases of the same spec going to ballot simultaneously. The work groups are also going to have trouble focusing on multiple releases simultaneously in terms of QA and preparation. As well, there's a huge amount of tooling and publication stuff that would be involved. Realistically, Sept. 2021 would be the soonest we could start an R5 - and that would mean zero downtime in between.
Rik Smithies (Jul 30 2020 at 21:03):
Sept 2021 - is that to start balloting R5? Does that correspond to R5 "gets pushed back by at least a year probably more". When would R5 be otherwise?
Lloyd McKenzie (Jul 31 2020 at 01:33):
R5 would go to ballot Jan 2021. Sept 2021 is a schedule with no downtime so starting R5 Jan 2022 is more realistic if we do R4b
Catherine Hosage Norman (Aug 15 2020 at 02:21):
Lloyd, can you clarify what R5 going to ballot in Jan 2021 includes? Could the GI tools be used or is this just a review of the resources? The Medication Definition resources would be included and there would be 3 ballot cycles and then published in 2022. The early posts made it sound like no R5 anything until second half of 2021.
Vassil Peytchev (Aug 15 2020 at 03:26):
Lloyd's post is regarding different timing options. AFAIK, there is no decision yet made on what the next ballot will look like.
Lloyd McKenzie (Aug 23 2020 at 18:23):
There is no firm decision on timing. The earliest ballot can happen is January. The earliest publication of anything could happen is end of Q2 2021. And that would be assuming a very limited scope. A full release would mean later publication - Q3 or Q4 2021.
Gopal Menon (Oct 19 2020 at 19:11):
Is there some place I can see the differences between R4 and the latest proposed R5 changes? I see this some changes listed: https://build.fhir.org/history.html. Is this the place to look?
Lloyd McKenzie (Oct 19 2020 at 23:51):
We won't come up with a comprehensive list of R5 changes until the time R5 goes out to ballot. For now, the only source of changes is looking at Jira tracker items (which is pretty fine-grained). Also note that some of the changes may well change again or even be reversed before the official R5 release is published in a couple of years.
Peter Jordan (Oct 20 2020 at 00:54):
There's also a 'Compare to R4' link at the bottom of each page in the Current Build which is useful if you're aware of where the changes might be.
Gopal Menon (Oct 20 2020 at 16:33):
Thanks!!!
Catherine Hosage Norman (Oct 27 2020 at 19:57):
Except if the resource changed names. Then you get a error.
Grahame Grieve (Oct 27 2020 at 20:50):
that means that the name change wasn't recorded somewhere...
Michael Lawley (Oct 28 2020 at 08:15):
It would be nice to see a diff between CapabilityStatement2 and CapabilityStatement :-)
Paul Lynch (Aug 05 2021 at 15:32):
Is there an expected date when R5 would be published?
Lloyd McKenzie (Aug 05 2021 at 15:43):
Current target is Q3 or Q4 2022
Catherine Hosage Norman (Aug 10 2021 at 15:25):
Is there an expected time when SUSHI and IG tool will support R5. It recognizes the resource SubstanceDefintion, but not the elements inside.
This line: * SubstanceDefinition.name.name 0..* MS
gets this error
info Converting FSH to FHIR resources...
error No element found at path SubstanceDefinition.name.name for DrugSubstance, skipping rule
File: C:\FHIR-us-pq-cmc\input\fsh\DefinitionalResources.fsh
It is odd that the error message says DrugSubstance and not SubstanceDefinition
Lloyd McKenzie (Aug 10 2021 at 15:43):
IG Publisher and SUSHI are different questions. The IGPublisher should support R5 IGs now, and if it doesn't, it suggests there's a bug. Ask about SUSHI support on the #shorthand stream.
