+
+      "Derivative Works" shall mean any work, whether in Source or Object
+      form, that is based on (or derived from) the Work and for which the

+      or contributory patent infringement, then any patent licenses
+      granted to You under this License for that Work shall terminate
+      as of the date such litigation is filed.

+   4. Redistribution. You may reproduce and distribute copies of the
+      Work or Derivative Works thereof in any medium, with or without
+      modifications, and in Source or Object form, provided that You

+          attribution notices from the Source form of the Work,
+          excluding those notices that do not pertain to any part of
+          the Derivative Works; and
+
+      (d) If the Work includes a "NOTICE" text file as part of its
+          distribution, then any Derivative Works that You distribute must
+          include a readable copy of the attribution notices contained
+          within such NOTICE file, excluding those notices that do not
+          pertain to any part of the Derivative Works, in at least one
+          of the following places: within a NOTICE text file distributed
+          as part of the Derivative Works; within the Source form or
+          documentation, if provided along with the Derivative Works; or,
+          within a display generated by the Derivative Works, if and
+          wherever such third-party notices normally appear. The contents
+          of the NOTICE file are for informational purposes only and
+          do not modify the License. You may add Your own attribution
+          notices within Derivative Works that You distribute, alongside
+          or as an addendum to the NOTICE text from the Work, provided
+          that such additional attribution notices cannot be construed
+          as modifying the License.
+
+      You may add Your own copyright statement to Your modifications and
+      may provide additional or different license terms and conditions
+      for use, reproduction, or distribution of Your modifications, or
+      for any such Derivative Works as a whole, provided Your use,
+      reproduction, and distribution of the Work otherwise complies with
+      the conditions stated in this License.
+
+   5. Submission of Contributions. Unless You explicitly state otherwise,
+      any Contribution intentionally submitted for inclusion in the Work
+      by You to the Licensor shall be under the terms and conditions of
+      this License, without any additional terms or conditions.
+      Notwithstanding the above, nothing herein shall supersede or modify
+      the terms of any separate license agreement you may have executed
+      with Licensor regarding such Contributions.
+
+   6. Trademarks. This License does not grant permission to use the trade
+      names, trademarks, service marks, or product names of the Licensor,
+      except as required for reasonable and customary use in describing the
+      origin of the Work and reproducing the content of the NOTICE file.
+
+   7. Disclaimer of Warranty. Unless required by applicable law or
+      agreed to in writing, Licensor provides the Work (and each
+      Contributor provides its Contributions) on an "AS IS" BASIS,
+      WITHOUT WARRANTIES OR CONDITIONS OF ANY KIND, either express or
+      implied, including, without limitation, any warranties or conditions
+      of TITLE, NON-INFRINGEMENT, MERCHANTABILITY, or FITNESS FOR A
+      PARTICULAR PURPOSE. You are solely responsible for determining the
+      appropriateness of using or redistributing the Work and assume any
+      risks associated with Your exercise of permissions under this License.
+
+   8. Limitation of Liability. In no event and under no legal theory,
+      whether in tort (including negligence), contract, or otherwise,
+      unless required by applicable law (such as deliberate and grossly
+      negligent acts) or agreed to in writing, shall any Contributor be
+      liable to You for damages, including any direct, indirect, special,
+      incidental, or consequential damages of any character arising as a
+      result of this License or out of the use or inability to use the
+      Work (including but not limited to damages for loss of goodwill,
+      work stoppage, computer failure or malfunction, or any and all
+      other commercial damages or losses), even if such Contributor
+      has been advised of the possibility of such damages.
+
+   9. Accepting Warranty or Additional Liability. While redistributing
+      the Work or Derivative Works thereof, You may choose to offer,
+      and charge a fee for, acceptance of support, warranty, indemnity,
+      or other liability obligations and/or rights consistent with this
+      License. However, in accepting such obligations, You may act only
+      on Your own behalf and on Your sole responsibility, not on behalf
+      of any other Contributor, and only if You agree to indemnify,
+      defend, and hold each Contributor harmless for any liability
+      incurred by, or claims asserted against, such Contributor by reason
+      of your accepting any such warranty or additional liability.

+# OpenTelemetry Baggage Log Record Processor
+
+[![NPM Published Version][npm-img]][npm-url]
+[![Apache License][license-image]][license-url]
+
+The BaggageLogRecordProcessor reads entries stored in Baggage from the parent context and adds the [baggage](https://opentelemetry.io/docs/concepts/signals/baggage) entries' keys and
+values to the log record as attributes on log emit.
+
+⚠ Warning ⚠️
+
+Do not put sensitive information in Baggage.
+
+To repeat: a consequence of adding data to Baggage is that the keys and values will appear in all outgoing HTTP headers from the application.
+
+Compatible with OpenTelemetry JS API and SDK `1.0+`.
+
+## Installation
+
+```bash
+npm install --save @opentelemetry/baggage-log-record-processor
+```
+
+### Usage
+
+Add to the log record processors that copies all baggage entries during configuration:
+
+```javascript
+import { NodeSDK, logs } from '@opentelemetry/sdk-node';
+import { ALLOW_ALL_BAGGAGE_KEYS, BaggageLogRecordProcessor } from '@opentelemetry/baggage-log-record-processor';
+
+const logRecordProcessor = [
+  new logs.SimpleLogRecordProcessor(
+    new logs.ConsoleLogRecordExporter()),
+  new BaggageLogRecordProcessor(ALLOW_ALL_BAGGAGE_KEYS)];
+
+const sdk = new NodeSDK({
+  serviceName: "example-service",
+  logRecordProcessor
+});
+
+sdk.start();
+```
+
+Alternatively, you can provide a custom baggage key predicate to select which baggage keys you want to copy.
+
+For example, to only copy baggage entries that start with `my-key`:
+
+```javascript
+new BaggageLogRecordProcessor((baggageKey: string) => key.startsWith('my-key'))
+```
+
+For example, to only copy baggage entries that matches the regex `^key.+`:
+
+```javascript
+const regex = new RegExp("^key.+")
+new BaggageLogRecordProcessor((baggageKey: string) => regex.test(baggageKey))
+```
