Subject: [VOTE] Accept NuttX into the Apache Incubator

Hi folks,


The [DISCUSS] thread on NuttX has died down.


Accordingly, I would like to call a VOTE to accept NuttX into the

Apache Incubator.


Please cast your vote:


  [ ] +1, bring NuttX into the Incubator

  [ ] +0, I don't care either way

  [ ] -1, do not bring NuttX into the Incubator, because...


The vote will open at least for 72 hours and only votes from the

Incubator PMC are binding, but votes from everyone are welcome.


=Abstract=

NuttX is a mature, real-time embedded operating system (RTOS).  It has wide usage in IoT projects,
control systems, robotics, drones, and many other systems.  Unique properties of NuttX are
its strict adherence to standards and its scalability. NuttX follows the Unix standards as
defined by OpenGroup.org (POSIX, ANSI, and others).  This allows for a high degree of portability.
Scalability is supported through a configuration system that allows NuttX to run on the smallest
embedded platforms and through high end single board computers.


=Proposal=

NuttX was released under a BSD 3-Clause license on February 17, 2007.  >From that time
until now it has been managed by a single person, Gregory Nutt.
The user base of NuttX has grown to probably thousands of projects and perhaps a hundred active
developments at any time.  The code base has grown to around 1.5 million lines of code (according
to OpenHub.com).

NuttX has benefited from this single person management because this has resulted in a consistent
architecture and controlled growth.  But now it is time to open this project to the participation
of others because this consistent architecture assures solid future growth, and because the
magnitude of effort required to support the RTOS exceeds the capability of a single person,
but also because users of NuttX require a stable road map going forward that does not depend
on a single person.

For these reasons, I propose that NuttX enter the Apache Incubator as a first step in opening
the project to wider participation.


=Initial Goals=

The initial goal will be to move the existing BSD code base to Apache and integrate with the
Apache development process and infrastructure. A primary goal of incubation will be to grow
and diversify the NuttX community. We will convert that code base to the Apache license during
incubation.


=Current Status=

As previously mentioned, NuttX is a mature, stable product in wide use in embedded products.


==Meritocracy==

We value meritocracy and we understand that it is the basis for an open community that encourages
multiple companies and individuals to contribute and be invested in the project’s future.
We will encourage and monitor participation and make sure to extend privileges and responsibilities
to all contributors.

Being a mature project, NuttX already has an extensive user base with many people who understand
the software, who have committed hundreds of changes, and are happy to participate in the
project.  I believe that with a little guidance and formalization, a PMC and a large group
of experienced committers can quickly be established.


==Community==

NuttX has a large, active community.  Communication is via a Google group at https://groups.google.com/forum/#!forum/nuttx
where there are 395 members as of this writing.  Code is currently maintained at Bitbucket.org
at https://bitbucket.org/nuttx/.  Other communications are through Bitbucket issues and also
via Slack for focused, interactive discussions.

Keeping up with the communications, requests for help, issues, and contributions is more than
a full time job at this time.


==Core Developers==

NuttX was initially developed by Gregory Nutt, released as an open source project on February
17, 2007, and is still under active development.  There are several dozen, active, frequent
contributors involved with the project.
The core OS can be considered finished at this point, but development continues in specialized
areas of networking, IoT, cryptography, tools, and other more specialized functions.


=Alignment=

NuttX is an original development with some small percentage of ported code.  It stands alone
depends on no other projects.


=Known Risks=

==Orphaned Products==

We are committed to the future development of NuttX and understand that graduation to a TLP,
while preferable, is not the only positive outcome of incubation.

Should the NuttX project be accepted by the Incubator, the prospective PPMC would be willing
to agree to a target incubation period of 2 years or less, knowing that every Incubator project
incurs a certain cost in terms of ASF infrastructure and volunteer time.


==Inexperience with Open Source==

None of the initial committers are Apache members and we will need some help in learning the
Apache Way.


==Salaried Developers==

It is expected that NuttX development will occur primarily on volunteer time, after hours.
 One initial committer will be paid by Xiaomi. All initial committers are all equally passionate
about the project.


=Relationships with Other Apache Products=

There is no relationship between NuttX and any other Apache Products.
There were discussions with the Mynewt project in the past concerning use of some Mynewt IoT
components within NuttX.  There is some possibility that those conversations could continue
once NuttX has Apache licensing as well.


=Required Resources=

==Mailing lists==

* dev@nuttx.incubator.apache.org

* commits@nuttx.incubator.apache.org

* private@nuttx.incubator.apache.org

The podling may also create a user mailing list, if needed.


==Source Control and Issue Tracking==

NuttX current uses the Bitbucket infrastructure for development.  It is likely that the NuttX
podling would switch to GitHub and would use Apache’s gitbox integration to sync between
GitHub and Apache infrastructure. The podling would use GitHub issues and pull requests for
community engagement.

Current Resources

* Initial source: https://bitbucket.org/nuttx/

* Wiki Page:  http://www.nuttx.org/

* Google Group:  https://groups.google.com/forum/#!forum/nuttx


=Source and Intellectual Property Submission Plan=

The NuttX  source code in Bitbucket is currently licensed under the BSD 3-clause license and
the most copyrights are assigned to the author, Gregory Nutt. If NuttX becomes an Incubator
project at the ASF, the project will transfer the source code and trademark ownership to the
Apache Software Foundation via a Software Grant Agreement.


=External Dependencies=

None.  A small number of files within NuttX follow slightly different, but compatible licenses
including BSD 2- and 4-clause, MIT, ISC, and Public Domain.


=Cryptography=

NuttX has negligible cryptographic capabilities at present.  This is, however, and are where
there will be extensive future growth.
