Subject Re: caffe and org.tensorflow licenses?
Date Mon, 24 Apr 2017 20:48:36 GMT

Hi Deron,

I had same doubt and hence have created the PR few days ago. We can
continue to discuss this on mailing list or the PR.

Even though we are not including the caffe/tensorflow project, we are
depending on their input/output format (i.e. proto files). Unfortunately,
both caffe and tensorflow don't have maven coordinates for their
input/output formats as they tend to use C++/Python wrappers created from
the proto files. Hence, we have to compile their proto files into java
classes. Personally, I think we should include their licenses into our jar.

TensorFlow => Apache 2.0 license
Caffe =>

Subject:	caffe and org.tensorflow licenses?


I see after a recent commit that the main jar file now gets caffe and
org.tensorflow packages added to it. This would tend to suggest that our
main jar needs modifications to its LICENSE file (and any other artifacts
containing the main jar would also need their LICENSES updated).

However, I see at
"Code generated by the Protocol Buffer compiler is owned by the owner
of the input file used when generating it.  This code is not
standalone and requires a support library to be linked with it.  This
support library is itself covered by the above license."

So could someone tell me if caffe and tensorflow licenses now need to be
added to the project?

Even if they are not required, some confusion during artifact validation
can occur since the project looks like it contains caffe and tensorflow
