@tsloughter, we have some resource semantic convention attributes as top-level constants in the SDK. We couldn't remove them because removing public symbols would be a breaking change. We have deprecated them but must continue to maintain them until the 2.0 release to remove them. Since we can't use ResourceAttriubtes from this package, can you keep the string equivalent for those constants here https://github.com/open-telemetry/opentelemetry-python/blob/main/opentelemetry-sdk/src/opentelemetry/sdk/resources/__init__.py#L92

@srikanthccv sorry I forgot about this comment!

Do you just mean the old FAAS attributes?

[srikanthccv]

Yes. It seems like there is another PR here that does the same #3251.

Ah, should I close this since there is the one to upgrade to 1.20? Or are both needed in order to publish a version of semconv at 1.19?

[srikanthccv]

I think you can close this. We haven't published the semantic conventions for each release.
