+# Log Attribute Semantic Conventions
+
+**Status**: [Experimental](../../document-status.md)
+
+The following semantic conventions for logs are defined:
+
+* [Log Media](media.md): Semantic attributes that may be used in describing the source of a log.
+
+Apart from semantic conventions for logs, [traces](../../trace/semantic_conventions/README.md), and [metrics](../../metrics/semantic_conventions/README.md),
+OpenTelemetry also defines the concept of overarching [Resources](../../resource/sdk.md) with their own
+[Resource Semantic Conventions](../../resource/semantic_conventions/README.md).

+# Semantic Conventions for Log Media
+
+**Status**: [Experimental](../../document-status.md)
+
+This document describes attributes for log media in OpenTelemetry. Log media are mechanisms by which logs are transmitted. Types of media include files, streams, network protocols, and os-specific logging services such as journald and Windows Event Log.

+## Log Media
+
+**Note:** The OpenTelemetry specification defines a [Resource](https://github.com/open-telemetry/opentelemetry-specification/blob/main/specification/resource/sdk.md#resource-sdk) as `an immutable representation of the entity producing telemetry`.
+The following attributes do not describe entities that produce telemetry. Rather, they describe mechanisms of log transmission.
+As such, these should be recorded as Log Record attributes when applicable. They should not be recorded as Resource attributes.
+
+### Log File
+
+**Description:** A file to which log was emitted.
+
+| Name                            | Notes and examples                                                                       |
+| ------------------------------- | ---------------------------------------------------------------------------------------- |
+| `log.file.name`          | The basename of the file. Example: `audit.log`                                           |
+| `log.file.path`          | The full path to the file. Example: `/var/log/mysql/audit.log`                           |
+| `log.file.name_resolved` | The basename of the file, with symlinks resolved. Example: `uuid.log`                    |
+| `log.file.path_resolved` | The full path to the file, with symlinks resolved. Example: `/var/lib/docker/uuid.log`   |
+
+### I/O Stream
+
+**Description:** The I/O stream to which the log was emitted.
+
+| Name                            | Notes and examples                                                                       |
+| ------------------------------- | ---------------------------------------------------------------------------------------- |
+| `log.iostream`        | The stream associated with the log. SHOULD be one of: `stdout`, `stderr` |
