+## Component Ownership
+
+This repository contains many components which are maintained by more than the typical set of JS maintainers and approvers.
+Each component in this repository SHOULD have a component owner who is responsible for maintaining it.
+The README.md for each component SHOULD contain its owner, but the source of truth for component ownership is in [.github/component_owners.yml](.github/component_owners.yml).
+Component owners are generally given authority to make decisions relating to implementation and feature requests for their components, provided they follow the best practices set out by the maintainers.
+Component owners MUST do their best to maintain a high level of quality, security, performance, and specification compliance within their components.
+Maintainers may override the decisions of component owners, but should only do so when they feel one or more of these traits is compromised.
+
+## Component Lifecycle
+
+This repository contains many components in various stages of the component lifecycle.
+A component may be **unreleased**, **experimental**, **beta**, **stable**, **unmaintained**, or **deprecated**; see the below definitions for each stability level.
+With the exception of the stable status, it is up to each individual [component owner](#component-ownership) to determine the status of a component.
+A component may only be marked stable with the approval of a member of @open-telemetry/javascript-maintainers; see the definition of stable below for more details.
+
+### Unreleased
+
+Unreleased components are in active development and have not yet been released to NPM.
+Unreleased packages should have the property `private` in their `package.json` set to `true`.
+
+### Experimental
+
+Experimental packages are in active development.
+They should be considered unstable and potentially unsuitable for production use.
+They are released to NPM for developers and early adopters.
+Experimental components MUST have their major version set to `0`.
+If a component does not have an explicit status in its README.md file, it should be considered to be experimental.
+
+### Beta
+
+Beta packages are not yet considered stable, but an effort should be made to preserve stability across versions if possible.
+They may be ready for production use, but users should understand that their APIs or the telemetry they output MAY change if required.
+Beta components MUST have their major version set to `0`.
+
+### Stable
+
+This is the highest level of quality and maintainership guarantee provided in this repository.
+Stable packages should be considered stable and ready for production use.
+In order for a package to be marked stable, it must meet the following requirements:
+
+- It MUST have a component owner that the JS maintainers feel confident will be responsive to issues and pull requests and will fulfill their responsibility competently.
+  If a component owner is not responsive to issues and PRs, the maintainers may assign a new owner or change the status of the component to unmaintained.
+- All relevant specification relating to the component MUST be stable. For example, telemetry emitted by an instrumentation library should rely on a stable semantic convention.
+- It MUST be reviewed and approved by a member of @open-telemetry/javascript-maintainers.
+
+Stable components MUST have their major version set to `1` or greater.
+
+### Unmaintained
+
+A component which does not have an assigned component owner, or has a component owner who has been unresponsive to issues and pull requests may be marked as unmaintained.
+Unmaintained components may continue to work and receive updates and fixes from contributors, but may not receive immediate attention if there is a problem or feature request.
+A component which is unmaintained may be deprecated if there is a problem that is not fixed in a timely manner.
+
+### Deprecated
+
+Deprecated components are no longer maintained and there are not currently plans to maintain them.
+They may not work and there are no guarantees for fixes or new features.
+Their source files may be deleted from the repository.
+Any packages released from their source will be marked as deprecated in NPM.

 ## Contributing Vendor Components
 
 This repo is generally meant for hosting components that work with popular open-source frameworks and tools. However, it is also possible to contribute components specific to a 3rd party vendor in this repo.

 **Resource Detectors**: OpenTelemetry can collect resource attributes of the entity that producing telemetry. For example, a process producing telemetry that is running in a container on Kubernetes has a Pod name, it is in a namespace and possibly is part of a Deployment which also has a name. All three of these attributes can be included in the `Resource`.

 The OpenTelemetry IdGenerator for AWS X-Ray generates trace IDs with its first four bytes set to the start time of the
 trace followed by a unique identifier consisting of 12 bytes of randomly generated numbers. OpenTelemetry offers an
 extension point which allows the usage of this custom IdGenerator as opposed to the out-of-the-box random IdGenerator,
 enabling compatibility with AWS X-Ray.

 The OpenTelemetry Propagator for AWS X-Ray provides HTTP header propagation for systems that are using AWS `X-Amzn-Trace-Id` format.
 This propagator translates the OpenTelemetry SpanContext into the equivalent AWS header format, for use with the OpenTelemetry JS SDK.
