+# OpenTelemetry Semantic Conventions
+
+The Semantic Conventions define a common set of (semantic) attributes which provide meaning to data when collecting, producing and consuming it.
+The Semantic Conventions specify attribute names, types, meaning and valid values, and provide descriptions and example usage.
+The benefit to using Semantic Conventions is in following a common naming scheme that can be standardized across a codebase, libraries, and platforms. This allows easier correlation and consumption of data.
+
+Semantic Conventions are defined for the following areas:
+
+* [HTTP](http/README.md): Semantic Conventions for HTTP client and server operations.
+* *Other areas can be found in the signal specific Semantic Conventions below*
+
+Semantic Conventions by signals:
+
+* [Resource](resource/semantic_conventions/README.md): Semantic Conventions for resources.
+* [Trace](trace/semantic_conventions/README.md): Semantic Conventions for traces and spans.
+* [Metrics](metrics/semantic_conventions/README.md): Semantic Conventions for metrics.
+* [Logs](logs/semantic_conventions/README.md): Semantic Conventions for logs and event data.

+# Semantic conventions for HTTP
+
+**Status**: [Experimental, Feature-freeze][DocumentStatus]
+
+This document defines semantic conventions for HTTP spans, metrics and logs.
+They can be used for http and https schemes
+and various HTTP versions like 1.1, 2 and SPDY.
+
+> **Warning**
+> Existing HTTP instrumentations that are using
+> [v1.20.0 of this document](https://github.com/open-telemetry/opentelemetry-specification/blob/v1.20.0/specification/trace/semantic_conventions/http.md)
+> (or prior):
+>
+> * SHOULD NOT change the version of the HTTP or networking attributes that they emit
+>   until the HTTP semantic conventions are marked stable (HTTP stabilization will
+>   include stabilization of a core set of networking attributes which are also used
+>   in HTTP instrumentations).
+> * SHOULD introduce an environment variable `OTEL_SEMCONV_STABILITY_OPT_IN`
+>   in the existing major version which is a comma-separated list of values.
+>   The only values defined so far are:
+>   * `http` - emit the new, stable HTTP and networking attributes,
+>     and stop emitting the old experimental HTTP and networking attributes
+>     that the instrumentation emitted previously.
+>   * `http/dup` - emit both the old and the stable HTTP and networking attributes,
+>     allowing for a seamless transition.
+>   * The default behavior (in the absence of one of these values) is to continue
+>     emitting whatever version of the old experimental HTTP and networking attributes
+>     the instrumentation was emitting previously.
+> * SHOULD maintain (security patching at a minimum) the existing major version
+>   for at least six months after it starts emitting both sets of attributes.
+> * SHOULD drop the environment variable in the next major version (stable
+>   next major version SHOULD NOT be released prior to October 1, 2023).
+
+Semantic conventions for HTTP are defined for the following signals:
+
+* [HTTP Spans](http-spans.md): Semantic Conventions for HTTP client and server *spans*.
+* [HTTP Metrics](http-metrics.md): Semantic Conventions for HTTP client and server *metrics*.
