Why the race link doesn't work?

I am new to FHIR. I was trying to research how race information is stored in FHIR. But the official URL for race doesn’t work. Can someone give me some advice? Thank you very much.


In general, there’s no requirement that extension URLs (or code system URLs - or any canonical URLs) will resolve. In this case, we intend this URL to resolve, but there was a publication issue with the most recent release of US Core that means that (for a little while) the URL doesn’t resolve as we would like it to. That’ll hopefully be fixed in a few weeks. In the meantime, you can certainly go browse the US Core spec to find the extension definition.

Good to know. Thank you so much lloyd!
