Using span relationships, attributes, kind, and the related [semantic conventions](https://github.com/open-telemetry/semantic-conventions/blob/main/docs/general/trace.md), we can more accurately describe the span in a way our tracing backend will more easily understand. The following example uses these mechanisms, which are described below.
