Thanks Chris.

I'll be creating such a proposal, and we'll continue from there. Looking
forward to any further instructions on this process.

Hi Itamar,

I think what you would do is throw together a proposal mentioning things

* who would be the initial committers for the project
* whether those committers have Apache ICLAs [1] on file, or not
* what¹s the rationale behind the project (yours would have strong
rationale, since Lucene is home to more than a few ports of the core Java
* what the licensing issues to be dealt with are
* what the affiliations of your current committers are

In general, whether you go the route of the Apache Incubator [2] or not,
these guidelines here [3] in general apply. You would then approach either
the Apache Incubator and grow your project there, with the intent of
graduating to a Lucene sub-project, or you could go to the Lucene PMC and
try to start a project directly there. Since I didn¹t follow the genesis of
the other Lucene ports, let¹s see what they think (I¹m CC¹ing general@lucene
to find out).
