Migrating from OpenTracing | OpenTelemetryBackward compatibility with OpenTracing has been a priority for the OpenTelemetry project from the start. To ease migration, OpenTelemetry supports the use of both the OpenTelemetry and OpenTracing APIs in the same codebase. This allows OpenTracing instrumentation to be recorded using OpenTelemetry SDKs.To accomplish this, each OpenTelemetry SDK provides an OpenTracing shim, which acts as a bridge between the OpenTracing API and the OpenTelemetry SDK. Note that OpenTracing shims are disabled by default.https://opentelemetry.io/docs/migration/opentracing/

3. Trace data structure 

Traces | OpenTelemetryTraces give us the big picture of what happens when a request is made by a user or an application.https://opentelemetry.io/docs/concepts/signals/traces/
