Arcade: Need to specify a license

[jaredpar]

Uploading a lot of code from difference sources now. What license should we be using here?

[Eilon]

Same as we use elsewhere for .NET Core? Some MIT/Apache license, (c) .NET Foundation?

[markwilkie]

Be sure and include the headers. @terrajobst has the specifics...

[chcosta]

License can apply to a few different things.

Repo

There's no license file in the repo at the moment even though most of the headers in files refer to one.

<!-- Copyright (c)  Microsoft.  All Rights Reserved.  Licensed under the Apache License, Version 2.0.  See License.txt in the project root for license information. -->

Can we just add this license to the repo?

https://github.com/dotnet/roslyn/blob/master/License.txt

Is the above mentioned header correct?

Package

For the package, we currently set the license to what RepoToolset defaults

<PackageLicenseUrl>http://go.microsoft.com/fwlink/?LinkId=529443</PackageLicenseUrl>

[weshaggard]

For the package license we should point to the license in this repo. See corefx as an example: https://github.com/dotnet/corefx/blob/master/Packaging.props#L17

<LicenseUrl>https://github.com/dotnet/corefx/blob/master/LICENSE.TXT</LicenseUrl>

[weshaggard]

For the repo license was under impression everything should be MIT (https://github.com/dotnet/corefx/blob/master/LICENSE.TXT) but I think that is a question for @richlander @terrajobst .

[chcosta]

@terrajobst @richlander , can you provide guidance?

[chcosta]

Current plan is to use the MIT license for this repo and target having that PR merged by EOD tomorrow (3/14). I'm hoping that gives enough time for feedback if there are issues with using the MIT license.

[terrajobst]

Use MIT. As I said earlier, the bigger question is whether you have director sign-off for the OSS release. I assume the answer to be yes.

[markwilkie]

@shawnro is getting an ACK

[terrajobst]

Cool. Just making sure we know who's volunteering to be fired if things go south ;-)

On top of using MIT, make sure to run the formatter to add the copyright/license headers if you haven't done so already. Don't do it manually.

[markwilkie]

We have approval from JoC

[terrajobst]

🤩

[chcosta]

Which formatter specifically are you referring to?

[weshaggard]

https://github.com/dotnet/codeformatter which is what we use in the core repos.

[chcosta]

I don't think the codeformatter works with Sdk style projects.

https://github.com/dotnet/codeformatter/issues/271

[jaredpar]

@chcosta is correct. It's broken until the Roslyn workspaces work goes through. Once that's there it will support SDK style projects.
