@adriaanm legally, can we do this?

[adriaanm]

Yes, assuming signed CLAs for all contributors since modularization

It seems like nearly all contributors since modularization (1 Jan 2013?) are also contributors to Scala, and therefore are recent and familiar faces that likely have a CLA on file. It wouldn't be hard to find the few exceptions to that group, and work on tracking them down and signing the CLA.

I mined the git history starting from 2013-07-17, and I've contacted a dozen contributors who I presumed didn't have a CLA on file. I've heard back from about half of them, so far. I'll report back whether I hear back from the rest.

Here's the form letter I'm sending.

Re: Scala contributor agreement

Dear <person's name>

I am one of the maintainers of scala-xml. I want to thank you for your contribution to scala-xml a while back. There is a new proposal to relicense much of Scala under the Apache License. As part of that initiative, I am contacting contributors of scala-xml. Would you let me know if you have signed the Lightbend CLA or, if not, whether you would be able to?

https://www.lightbend.com/contribute/cla/scala

From the page above, click on the link "Sign the agreement using your github account", which is this URL:

https://www.lightbend.com/contribute/cla/scala/sign

You'll be asked to sign-in with your GitHub account, and then submit your confirmation to Lightbend.

For more information on the initiative of moving from the "modified" BSD license to Apache 2.0 license, see the following post on the Scala contributor forum (Discourse):

Thanks,
Aaron
