[carlosalberto]

The OT Shim layer needs to be updated to include the latest changes as introduced by

open-telemetry/opentelemetry-specification#1101
open-telemetry/opentelemetry-specification#1563

I'm not sure with this is required for GA cc @dyladan @obecny

[carlosalberto]

@vmarchaud It's not required for 1.0, for sure (as it's still marked as Experimental).

Chunking up the updates:

• add shim constructor with custom propagators [done]
• spanShim.setTag updates [done]
• spanShim.log updates [done]
• span context immutability and managing association with span

I can work on the setTag updates next, will not claiming anything else at the moment :)

@carlosalberto do you think the Span/SpanContext Shim section applies to OTEL-JS? I'm trying to wrap my head around it, and it seems out of scope because:

• the requirement is stemming from multithreading concerns (not super familiar with evolving Node APIs, but I don't think that applies)
• OpenTracing-JS never implemented Baggage inside SpanContext
• OpenTracing-JS never implemented ScopeManger

WDYT?

It looks like the last part was out of scope, everything else is done, so I'll close this issue. 🙂

If someone comes across this issue and determines that something else is missing, please open a new one so we don't overlook the comment here on this closed issue. Thanks :)
