Pull request overview
This PR documents the mapping between gRPC native OpenTelemetry conventions (defined in gRPC proposals A66 for metrics and A72 for tracing) and the official OpenTelemetry semantic conventions for gRPC hosted in this repository. The documentation helps users understand how to convert between the two convention systems.
Key Changes
- Adds a new compatibility document (
docs/non-normative/compatibility/grpc-compatibility.md) providing detailed mappings for metrics, spans, and their attributes - Updates the gRPC conventions page to reference the new compatibility document
- Removes duplicate gRPC convention references from the RPC README
