Subject Re: Feedback on updated NOTICE and LICENSE files (was: [VOTE] Release Kafka 0.7.0-incubating)
Date Tue, 06 Dec 2011 08:31:04 GMT
Normally, when you ship the dependency together with your own
product/project, then (AFAIK) that bigger work needs the NOTICE. If
you don't ship it, let's say that you call it a "System Requirement"
or "Optional Plugin", then you don't need it.

ALSO, more importantly, it looks like Voldemort depends on BDB Java
Edition, which I think was discussed at length some years ago on
legal-discuss@ but is not mentioned explicitly on I think the problem is that
it seems to demand that all downstream users must ship source code,
i.e. some odd form of virality. Even more reasons to check with the
Legal committee...
