Thanks @julianocosta89!

Here are the additional items we need to consider:

1. Confirm with the original author(s) regarding licensing / copyright.
2. Check if there are licensing / copyright issues related to dependencies / submodules / etc.
3. Decide how much history / changelog are we going to keep.
4. Do we need to preserve the commit history from the original source? (I guess the answer is no - by looking at other donations to OpenTelemetry).

@mtwo, @jsuereth, can you provide guidance on the licensing / copyright changes we should be making. I think our preference is for the copyright owners to be OpenTelemetry itself right, @reyang?

I think so (?), though I'm not an expert at this. @lizthegrey and possibly @tedsuo know way more about this than I do.

OpenTelemetry community would prefer the copyright to be "OpenTelemetry Authors" - https://github.com/open-telemetry/community/blob/4b53b7ffb6390e57850e9a916bd63253349a7770/CONTRIBUTING.md#copyright-notices. But this has to be blessed by the previous author(s) (I think they have the ultimate saying, unless it's documented in a different way).

Here goes an example - I worked with .NET Foundation and the ASP.NET team to get their bless on open-telemetry/opentelemetry-dotnet#2225.

There are different examples - e.g. .NET auto-instrumentation https://github.com/open-telemetry/opentelemetry-dotnet-instrumentation/blob/main/src/OpenTelemetry.AutoInstrumentation.Native/lib/fmt_x64-windows-static/share/fmt/copyright.

What @reyang said.

Here goes a summary of existing copyright info (by scanning through the temporary online-boutique branch):

Copyright <year> the original author or authors.
https://github.com/open-telemetry/opentelemetry-demo-webstore/blob/b9b5998270877d92e56e69883028c278d0d2d85f/src/adservice/gradlew.bat#L2

Copyright © <year> the original authors.

Copyright <year> The gRPC Authors
https://github.com/open-telemetry/opentelemetry-demo-webstore/blob/b9b5998270877d92e56e69883028c278d0d2d85f/pb/grpc/health/v1/health.proto#L1

In this case, since it's forking a long-established project, I think we credit OpenTelemetry Authors for any significant modifications, but we leave the existing copyrights alone.

Based on my investigation, it seems everything in the current online-boutique branch should be compatible with Apache License, Version 2.0 (disclaimer: I'm not an attorney).

The copyright information shouldn't be a blocker if we follow what @lizthegrey suggested.

Great thanks for the help. @julianocosta89 we should be okay from a licensing perspective. We'll follow Liz's guidance

@julianocosta89 I think steps 3 & 4 are now done. Please review then complete the merge if possible

Just merged the pr into main & deleted the branch. Closing this issue.
