**Status**: [Experimental][DocumentStatus]
|
|
|

This document defines trace semantic conventions used by the
|
|
compatibility components, e.g. OpenTracing Shim layer.

## OpenTracing
|
|
|
|
`Link`s created by the OpenTracing Shim MUST set `opentracing.ref_type`
|
|
with one of the accepted values, describing the direct causal relationships
|
|
between a child Span and a parent Span, as defined by
|
|
[OpenTracing](https://github.com/opentracing/specification/blob/master/specification.md).
|

<!-- semconv opentracing -->
|
|
| Attribute | Type | Description | Examples | Requirement Level |
|
|
|---|---|---|---|---|
|
|
| `opentracing.ref_type` | string | Parent-child Reference type [1] | `child_of` | Recommended |
|
|
|
|
**[1]:** The causal relationship between a child Span and a parent Span.
|
|
|
|
`opentracing.ref_type` MUST be one of the following:
|
|
|
|
| Value | Description |
|
|
|---|---|
|
|
| `child_of` | The parent Span depends on the child Span in some capacity |
|
|
| `follows_from` | The parent Span doesn't depend in any way on the result of the child Span |
