Subject Re: Apache Metron - licensing question
Date Thu, 13 Apr 2017 13:27:22 GMT
Hi Josh,

Can you specify which message you're referring to?  I did get some feedback
on the Metron dev mailing list from a mentor and from a PMC member, I get
the feeling that nobody else in the community is comfortable answering this
sort of question.  Should I perhaps ask this to the legal-discuss mailing
list?  Happy to do whatever is necessary to bring this to resolution.
Thanks,

Jon
