Julian Hyde commented on CALCITE-6098:
--------------------------------------
It is very likely the case that I copied from ORC. I remember looking at ORC's
site and reading their .md source code before settling on Jekyll for Calcite. I
don't remember whether I let Jekyll create the initial site or copied from ORC.
Did we just copy examples/skeleton files? If so, I don't think we need to add
the Jekyll license to our NOTICE. It is analogous to me copying a Java "Hello
world" program to start my project: it is so simple that there is only one way
to do it, and since no creativity is required there is [nothing to
copyright|https://www.linkedin.com/pulse/hello-world-copyrighted-ido-tuchman/].

> Key: CALCITE-6098
> URL: https://issues.apache.org/jira/browse/CALCITE-6098
> Project: Calcite
> Issue Type: Task
> Affects Versions: 1.36.0
> Reporter: Stamatis Zampetakis
> Assignee: Stamatis Zampetakis
> Priority: Major
> Labels: pull-request-available
>
> The NOTICE file contains the following statement:
> {noformat}
> The web site includes files generated by Jekyll.{noformat}
>
> However, there is nothing in the [LICENSE of Jekyll
> |https://github.com/jekyll/jekyll/blob/3f3a283018a976da11a0bfcc13a20d43d37ee29f/LICENSE]
> that requires such attribution.
> According to the instructions of composing the [NOTICE
> file|https://infra.apache.org/licensing-howto.html#mod-notice] for ASF
> projects we shouldn't add anything in there that is not *legally* required.
> Moreover the generated files are not necessary licensed under the same
> LICENSE with the generator.
> JavaCC, ANTLR, and lots of other source generators use a variety of licenses
> but the generated output is not licensed under the same terms. For instance,
> Calcite uses JavaCC, which is licensed under
> [BSD-3|https://github.com/javacc/javacc/blob/master/LICENSE] but both the
> grammar as well as the generated .java files are AL2.
> As long as we are not packaging bits of Jekyll in Calcite there is no need to
> add explicit mentions in LICENSE or NOTICE files.
