relaxing some constraint for CodeSystem loading

[Rosnyni]

Hello,

We tried to use your tool for IG loading in our FHIR server, but we face an issue.

The IG CodeSystem are not FHIR native : we took input information from another information system.

This other IS store a startdate for every concept. StartDate that is initiated at 0001-01-01.

This syntacticaly correct date however lead to a blocking error when loading the codeSytem that is therefor not loaded:

Would it be possible to do something about this ?

Sincerely

Nicolas Griffon

Is this a public IG that I could test with?
(sorry for the delay, didn't notice the post - easier to reach me on the fhir chat too - but do report here so that it's tracked and others find them too)

That's an interesting issue there, note that my tooling uses the open source parsers to check the content, so if you try and pass this content to other servers that also use these parsers they are likely to fail too.
So you might get it past my tool, but then fail trying to load it into the server.
My advice would be to fix your code systems in the source package to ease your processing downstream, this isn't likely to be the only place things will break.

Thanks for the look at our issue

I'm affraid it is not a public IG :-/
We are working on making our IG public but there is a lot to do before we can...

However, is it possible to know the parsers you use ? In order for us to bring them our feedback and, may be, they'll enhance their tools.

It's using the Firely SDK parsers that most on the dotnet stack use.
I can configure it to be "more lenient" and handle those, but you'll likely then just get that problem soon as the server it's deploying to gets it (e.g. the MS FHIR Server)

The code is linked here:

UploadFIG/UploadFIG/R4_Processor.cs

Line 22 in aeb7a05

FhirJsonParser _jsonParser = new FhirJsonParser(new ParserSettings() { AcceptUnknownMembers = true, AllowUnrecognizedEnums = true, PermissiveParsing = true });

And the Firely SDK currently in use is 5.11.1
