Subject Re: Does Zipkin need to sign a SGA ?

Hi Mick,

tldr; with my Incubator PMC hat on, "all that needs to be done" is to establish that all of
the copyright owners sign either a Software Grant or an ICLA.

In order to establish that Apache has the rights to the code base, every line of code needs
to have its provenance researched. 

Looking at the proposal it seems like most
of the code is in the github repository . Is there any
code coming from another source? Was the original code from Twitter granted to OpenZipkin?
Is there any documentation of that copyright transfer? Does Twitter retain any rights?

The capitalization of the "Initial Source" section is a bit strange. But can we assume that
the only committers to the project are listed at

The proposal also says that "All source code is copyrighted to 'The OpenZipkin Authors', to
which the existing core community(members list in Initial Committers) has the rights to re-assign
to the ASF. " 

It looks like there were many people who contributed a few lines of code. Did they sign anything
like a Contributor Agreement that grants their copyright to The OpenZipkin Authors?

ASF Secretary.
