Missing copyright notice as required by Apache 2.0 license

[robcowart]

For the Apache 2.0 license to be applicable it is necessary to include a copyright notice and license claim. This requirement is established here...

"Work" shall mean the work of authorship, whether in Source or Object form, made available under the License, as indicated by a copyright notice that is included in or attached to the work (an example is provided in the Appendix below).

Can you please add a NOTICE file which includes the copyright notice (including your details as copyright owner) and license claim from the Appendix of the Apache 2.0 License? This will make the use of the license valid and help to get applications using this module through legal review.

Your help here would be much appreciated.

My understanding is that NOTICE files are only required for projects in the Apache Software Foundation.

That isn't the plain reading of the Apache 2.0 license. I am not sure if any of the commenters on those posts are lawyers, but the legal department of a few of our customers state otherwise, including one which has a whole team that do nothing but open source compliance. Even GitHub says you need a copyright notice for the Apache 2.0 license (see "conditions" below), and I am sure their legal team reviewed that before they took such a stance.

If you think about it, it makes sense. Only the copyright holder has the legal right to license the code. Without a copyright notice there is ambiguity as to who actually has the rights to assign a license, and thus whether the assignment of Apache 2.0 is even valid. Regardless of the license, it is always a good idea to include a copyright notice, as it eliminates this ambiguity.

In the end there is no downside for a copyright notice to be included, but it does eliminate potential issues for those wishing to use the project.
