Incubator PMC report for December 2014

The Apache Incubator is the entry path into the ASF for projects and codebases
wishing to become part of the Foundation's efforts.

There are currently 36 podlings undergoing incubation.  Two podlings joined 
us this month, NiFi and Tamaya.  Five new IPMC members and two new 
Shepherds joined our ranks as well.

 with few being closed.

  Droids still has an open name search.
  Falcon is procesing a name search currently.
  Tamaya successfully cleared Podling Name Search.

  Two podlings (BatchEE and Johnzon) are currently waiting
  on the result of a new licensing agreement w/ Oracle to
  gain access to the TCKs for new EE related JSRs.  Until this
  is done they could not be considered compliant implementations

* Infrastructure

  SVN outage caused minor inconvenience to some podlings.
  Argus/Ranger is facing some struggles with their rename.

* Miscellaneous

  The Kalumet podling is currently thinking about throwing around a
  retirement vote. The Samza community is voting on a draft graduation 
  resolution. There is a vote underway to recommend retiring for the
  NPanday. Hadoop Development Tools community has voted to retire from the
  Incubator.

Brooklyn

Brooklyn is a framework for modelling, monitoring, and managing applications
through autonomic blueprints.

Brooklyn has been incubating since 2014-05-01.

Three most important issues to address in the move towards graduation:

  1. Completing our first release under Apache
  2. Grow the community
  3. More diversity of the committers/PPMC (currently biased towards
     employees of a single organization)

Any issues that the Incubator PMC (IPMC) or ASF Board wish/need to be
aware of?

  None.

How has the community developed since the last report?

  Our community continues to grow slowly but surely, and has received
  interest and contributions from new community members.

  We had the opportunity to talk about our project at ApacheCon Europe
  last week, which has introduced Brooklyn to a wider audience within
  Apache.

How has the project developed since the last report?

  Code continues to be proposed and merged at a high rate. We are
  satisfied with our technical velocity.

  We are currently in the process of making our first release. As is
  common with incubating project's first releases, this involves several
  iterations and ongoing discussions with mentors and IPMC.

Date of last release:

  No release yet, but we have begun the process for our first release
  and aim to release as soon as we possibly can.

When were the last committers or PMC members elected?

  No change since 2014-07-02.

Ripple

Ripple is a browser based mobile phone emulator designed to aid in the development of HTML5 based mobile applications. Ripple is a cross platform and cross runtime testing/debugging tool. It currently supports such runtimes as Cordova, WebWorks and the Mobile Web.

Ripple has been incubating since 2012-10-16.

Any issues that the Incubator PMC (IPMC) or ASF Board wish/need to be aware of?
The community recently discussed the lack of growth in the project. Some members felt that retirement of the podling was appropriate. Others have stepped up to take over essential tasks and attempt to build a community. We have agreed with mentors to review this situation in 6 months. It is possible that Ripple is no longer important as its functionality is potential being replaced by Cordova-browser.  Our original champion, Ross Gardler has also up to help evaluate the situation.  For Cordova-browser idea, there was also a discussion on the mailing list.  

How has the community developed since the last report?
No new committers since last June 2014. 

How has the project developed since the last report?
Minor user contributions.

Date of last release:
No release made as yet, this will be the first item to recieve attention. 

When were the last committers or PMC members elected?

--------------------
Sentry

Sentry is a highly modular system for providing fine grained role
based authorization to both data and metadata stored on an Apache Hadoop
cluster.

Sentry has been incubating since 2013-08-08.

Three most important issues to address in the move towards graduation:
  1. Continue to grow the Sentry community
  2. Initiate graduation discussion with community and address any
     potential concerns raised
  3. Update project status page, website etc

Any issues that the Incubator PMC (IPMC) or ASF Board wish/need to be aware of?
  None

How has the community developed since the last report?
  The community is growing. Several new members have started actively
  contributing to the project. New contributors made a significant
  contribution in patches as well as release activity. The user group
  meetup at NYC was well attended. Community members presented Apache
  Sentry at various community meetups around the world, include Hadoop
  group meetup in Hydrabad, India and ApacheCon Europe in Budapest, Hungary

How has the project developed since the last report?
  A number of new features implemented in the master codeline. The sentry
  community is working towards removing some of the non Apache dependencies
  in order to avoid any potential concerns for the graduation processes.

Date of last release:
  2014-08-19

When were the last committers or PMC members elected?
  Arun Suresh and Tuong Truong have been added as a committer as announced

--------------------
Streams

Apache Streams (incubating) is a lightweight (yet scalable) framework for ActivityStreams.

Streams has been incubating since 2012-11-20.

  The project provides a framework for abstracting away individual data
  schemas and API protocols from solutions built to collect, publish,
  process, and analyze digital activity data, as well as a community-
  driven process for determining best practice usage of the ActivityStreams
  specification with real-world datasets - valuing working, tested,
  adaptable, useful code over strict adherence to existing specs.
  Importantly, the project does not impose one execution framework -
  modules built to Apache Streams interfaces and coding standards may
  be instantiated within multiple JVM-based runtime containers, including
  popular ‘big-data' frameworks.

Three most important issues to address in the move towards graduation:

  1.  Establish and maintain a consistent release process.
  2.  Improve quality of code, tests, documentation, and examples.
  3.  PPMC must relieve project mentors of all responsibility for the
      project's adherence to the Apache Way and long-term viability.

Any issues that the Incubator PMC (IPMC) or ASF Board wish/need to be
aware of?

  No.

How has the community developed since the last report?

  Ryan Ebanks was voted in as committer and PPMC member on 10-17-2014.

Tamaya

Tamaya is a highly flexible configuration solution based on an modular,
extensible and injectable key/value based design, which should provide a
minimal but extendible modern and functional API leveraging SE, ME and
EE environments.
Tamaya has been incubating since 2014-11-14.

​​Three most important issues to address in the move towards graduation:
  1. ​​Project web site must be setup (ongoing).
  2. ​​​​Establish a collaboration model within the community and ensure a
     common view on the main focus points.
  3. ​Improve code base for being ready for a first release around Q1 2015.​

​​Any issues that the Incubator PMC (IPMC) or ASF Board wish/need to be
aware of?
  No.

​​How has the community developed since the last report?
  Many of the committers have successfully filed the ICLA and also ​started
  to contribute, some of them already by doing first patches. ​Feedback in
  the community was overwhelming. We could also successfully place the
  topic at conferences as well as in the German Java Magazin and other
  events.​ Also interest of people during the Zurich Hackergarten in
  November was great and will definitely lead to additional committers
  early 2015.

​​How has the project developed since the last report?
​  The project setup is going quite well. Initial committers are onboarding,
  the initial code donation was successfully moved and other preconditions
  like the project name, IP clearance, Jenkins etc. were successfully done.​
  Thanks to INFRA for their incredible support!

​​Date of last release: ​Still getting started.

​​When were the last committers or PMC members elected?
  Still getting started.

Taverna

Taverna is a domain-independent suite of tools used to design and execute
data-driven workflows.

Taverna has been incubating since 2014-10-20.

Three most important issues to address in the move towards graduation:

  1. IP clearance to be signed by Univ of Manchester
  2. Move source code, wiki, issues to apache.org. Restructure git repos.
  3. Invite contributors who volunteered at October workshop

Any issues that the Incubator PMC (IPMC) or ASF Board wish/need to be
aware of?

  Infrastructure bootstrapping takes a long time and requires a series of
  requests. E.g. Taverna incubator has been approved, but does not get a
  web-site without explicitly asking for it. Documentation for apache.org
  infrastructure assumes you are already a long-term committer.


How has the community developed since the last report?

  Transition of mailing list succcessful (? - can we get some numbers?).

  Most of the proposed initial committers have sorted CLAs
  https://wiki.apache.org/incubator/TavernaProposal#Initial_Committers
  and received apache.org account - see
  https://people.apache.org/committers-by-project.html#taverna

  Many of the remaining initial committers have not been active in the
  recent years. We're following up these (and others) through private
  conversations. There's been some confusion with regards to the term
  "committer" - some were scared and thought it meant they had to make
  a committment to work on the source code!

  Not much further development - worried that dev@taverna are scared away
  by the long-dragged bootstrapping which dominates the list.

How has the project developed since the last report?

  Source code is being restructured at https://github.com/taverna-incubator
  before being staged to import into git.apache.org

  Normal development continues at https://github.com/taverna/ - due to
  prepare the final 2.5.1 non-Apache release.

  Stian Soiland-Reyes was at ApacheCon in Budapest, fruitful discussions
  with mentor Andy Seaborne and Gavin McDonald from INFRA with regards to
  the transitioning of Taverna's existing source code repository, wiki and
  issue tracker (luckily git->git, confluence->confluence and jira->jira).

Date of last release:

  No release since incubation.

When were the last committers or PMC members elected?

  No new committers or PMC members elected since incubation.

Shepherd/Mentor notes:

  As noted the email list just been migrated and code repo setup, but
  already show good signs of activity on the email list.  Code
  activity seems good so far although it's still on it's own github repo.


--------------------
Wave

A wave is a hosted, live, concurrent data structure for rich communication. It
can be used like email, chat, or a document.

Wave has been incubating since 2010-12-04.

Three most important issues to address in the move towards graduation:

  1. Making release.
  2. Growing community.
  3. Source fixes/improvements.

Any issues that the Incubator PMC (IPMC) or ASF Board wish/need to be
aware of?
  No


How has the community developed since the last report?
  After some spike in activity we had a slowdown.


How has the project developed since the last report?
  Some improvements were committed like full text search with Solr and some
  more need to be reviewed/merged. We are working on making an updated RC
  and plan to hold review/voting soon.
