Topic: DocumentReference Date
Drew Torres (Jul 15 2020 at 19:43):
@John Moehrke What is the intent of DocumentReference.Date? Is it intended to represent the initial DocumentReference creation date, or the date that this version was created?
Drew Torres (Jul 15 2020 at 19:49):
Part of the problem is how DSTU2 created and index were 2 fields, but now we only have date.
Drew Torres (Jul 15 2020 at 19:50):
The definition is a bit vague.
John Moehrke (Jul 15 2020 at 20:02):
There is no mapping to XDS for the .date field. So it is not used in my world. I really don't know why it is there. The .content.attachment.creation is where the creation dateTime of the document bits. And .lastUpdated would cover last updated. So All that is left is the creation of the DocumentReference resource. I would be happy to entertain a CR to remove it.
Drew Torres (Jul 15 2020 at 20:02):
LOL that would really tick people off because we have to implement this field for us-core.
Drew Torres (Jul 15 2020 at 20:03):
We are having a hell of time mapping it now.
John Moehrke (Jul 15 2020 at 20:05):
why would that tick people off... it certainly would not hurt people that are not understanding it... so whoever might be mad, should tell us what the new definition should be.
John Moehrke (Jul 15 2020 at 20:05):
note that OO block vote outstanding has major breaking changes...
Drew Torres (Jul 15 2020 at 20:08):
Well the regulation calls out us-core IG to implement, and US-Core has documentreference.date as being must support.
Drew Torres (Jul 15 2020 at 20:09):
We may end up having to add a new column just for this field because we don't support this field.
John Moehrke (Jul 15 2020 at 20:11):
well, who set it to MS? Why did they do that? Why did no comment complain that MS was on an element that people didn't know how to fill?
Drew Torres (Jul 15 2020 at 20:13):
I know at the time I didn't look at it as closely as I should have, and was in surgery during voting time to vote on the ballot.
John Moehrke (Jul 15 2020 at 20:14):
well.. I tried to get US-Core to just use IHE-MHD... which would have made this more clear... but I lost that argument too.
Drew Torres (Jul 15 2020 at 20:15):
Well both you and I wanted to merge DiagnosticReport and DocumentReference....
Vassil Peytchev (Jul 15 2020 at 20:26):
Based on the description, it seems to represent the timestamp of when the resource instance was created, not a version-specific creation timestamp...
John Moehrke (Jul 15 2020 at 20:27):
that is the best I came to. the creation timestamp for the DocumentReference resource itself
John Moehrke (Jul 15 2020 at 20:27):
which was kind of the same meaning of .indexed element....
John Moehrke (Jul 15 2020 at 20:28):
with the purpose of this being when the DocumentReference was first known to that FHIR Server
Vassil Peytchev (Jul 15 2020 at 20:41):
.indexed is the alternate name for it.
