Incubator PMC report for January 2015

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.  One podling 
joined us this month (Corinthia). One member joined and two members
left the IPMC.

IPMC has recognized the need for tightening up mentorship requirements
and overall structure of the incubation process. Active discussions
on how to this in the best possible way are on going and the recommendation
is expected to be available in a few weeks.

* New Podlings

    Corinthia
    Zeppelin

* Graduations

  The board has motions for the following:
     
    Samza



* Releases

  The following releases were made since the last Incubator report:

    Dec 05 2014   Apache Falcon 0.6-incubating
    Dec 08 2014   Apache Samza 0.8.0-incubating
    Dec 22 2014   Apache Brooklyn 0.7.0-M2-incubating

* IP Clearance

  * Corinthia initial source grant

* Legal / Trademarks



* Infrastructure



* Miscellaneous

  * NPanday community seems to be in agreement that retirement is the best
    option at this point. The only outstanding issue before formally
    recommending graduation VOTE is to decide whether there's enough cycles
    available for one last release before retirement.

--------------------
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. Grow the community
  2. More diversity of the committers/PPMC (currently biased towards
     employees of a single organization)
  3. Following up our first release with further, regular, releases

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
  recently, 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 recently completed our first release as an Apache project, and
  look forward to following this up with regular releases from now on.

Date of last release:

  2014-12-23 (apache-brooklyn-0.7.0-M2-incubating)

When were the last committers or PMC members elected?

  No change since 2014-07-02.

Shepherd/Mentor notes:

  Chip Childers (chipchilders):
  
    The Brooklyn community is doing very well in learning the rules /
    policies / nuances of working at the ASF. It still needs a bit more time
    to build up a diverse community IMO, but things are looking good.

  David Nalley (ke4qqq):
  
    The Brooklyn folks kicked out their first release during this reporting
    cycle, which is an important milestone. Work still remains in terms of
    building a diverse community.

--------------------
Calcite

Calcite is a highly customizable engine for parsing and planning queries on
data in a wide variety of formats. It allows database-like access, and in
particular a SQL interface and advanced query optimization, for data not
residing in a traditional database. (Renamed from Optiq on 2014-09-30.)

Calcite has been incubating since 2014-05-19.

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

  1. Continue to build community
  2. Add more committers and PPMC members
  3. Demonstrate community robustness by rotating project tasks among
     multiple project members

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?

  In December, there were 84 messages on dev@, 45 commits, 50 issues
  created, 27 issues resolved by 7 contributors.

  Julian Hyde gave a talk "SQL on everything, in memory" about Calcite
  at the Strata + Hadoop World conference in October, and held an
  "office hour" with interested community members. He also spoke at
  a Hive meet-up in New York and a Kylin meet-up in San Jose about
  how those projects integrate with Calcite.

  Collaborations are under way with other Apache projects: with Drill
  to make implementation convention more neutral; with Hive for join
  algorithm selection, and leveraging sorted data; and with Phoenix
  to create a Calcite adapter for Phoenix.

How has the project developed since the last report?

  We have completed the rename from Optiq to Calcite. We have also
  re-organized the code into the org.apache.calcite namespace. We are
  planning to make a 1.0 release in January with the re-organized
  code.

Date of last release:

  2014-11-05 (0.9.2)

When were the last committers or PMC members elected?

  PPMC member elected in December (but has not yet accepted).

Shepherd/Mentor notes:

 John D. Ament (johndament):

   The podling is working through its first release slowly.  First release
   is always the hardest.  Good activity for a new podling on the lists,
   still waiting on the board report though.

A unified In-Memory Data Fabric providing high-performance, distributed in-
memory data management software layer between various data sources and user
applications.

Ignite has been incubating since 2014-10-01.

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

  1. Finish migration to Apache process.

Shepherd/Mentor notes:

  Alan Cabrera (adc):

    This podling is off to a great start.  Mentors are extremely active
    participants with most of the non-Jira chatter being between Dmitriy
    Setrakyan and the mentors; look to the Jira issue to see the rest of the
    community "getting it done".  The "issues to be addressed" section seems
    reasonable.

  Branko Čibej (brane):

    I agree with Alan's assessment, but I'd really like to see more
    activity on the dev@ list; especially more of the initial committers
    getting involved in discussions there. Whilst Jira notifications are
    nice, I have a nagging feeling that most of the discussions within
    the community are happening off-line, which leaves a rather large
    hole in the community's collective memory (i.e., mail archives).
    This will have to be addressed before graduation.

--------------------

Kalumet

Kalumet a complete environment manager and deployer including J2EE
environments (application servers, applications, etc), softwares, and
resources.

Kalumet has been incubating since 2011-09-20.

Community Developement:

  Apache Kalumet 0.6-incubating version has been released.  However, due to
  some misunderstanding, the release vote has not been completed by 3 IPMC.
  Especially, some legal files issues have been raised.
  
  We are preparing a 0.6.1-incubating release to fix the legal files and
  submit to IPMC vote.

  We are in the way of promoting the documentation on the website.

Project Development:

  We are preparing the 0.6.1-incubating (plan for December, 27) to fix the
  legal files issues raised on 0.6-incubating release and have a complete
  IPMC vote.

  We are preparing the 0.7-incubating release with the development changes.

  A new contributor has been identified and started to work on some issues
  and refactoring of the webconsole (mockup provided using Vaadin).

  Local branches have been created containing:
  
  - new model and REST API
  - new webconsole (remove of Echo framework)

  These local branches will be merged on the 0.7-incubating branch (master).

  Before Graduation:

  - The documentation has been updated and aligned with the 0.6-incubating
    release. The documentation will be promoted on the website and "linked"
    in announcement e-mails as soon as the 0.6.1-incubating release has been
    voted.
  - The 0.7-incubating release will fix the graduation issue, especially in
    term of license (removal of Echo2 framework for the UI).

  Post Graduation:

  - Kalumet scripts. It's the extension of the "software" concept globally
    to all Kalumet resources. It will allow users to create custom
    deployment/update plan, with a set of fine-grained steps.

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

  None so far.

Date of last release:

  2013-11-22

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

  1. Migrate source code and issue tracking from github.com to Apache Git
     and JIRA
  2. Make the first release from apache
  3. Make project website available on apache

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

  * Nothing

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 develop new feature, fix bugs, refine web experience.  The
  Kylin meetups at Bay Area and Beijing was well attended.  Apache Kylin has
  been presented at Big Data Technology Conference 2014, Beijing which is
  one of biggest Big Data conference in China.  Interest of people during
  that event was great and engaged a lots of organizations and individuals,
  many of them started to evaluate and joined Kylin community.

How has the project developed since the last report?

  1. The project setup is going quite well. Initial committers are
     onboarding, JIRA, mailing list were successfully done, Web content has
     been migrated to Apache Git but need tuning. Main source code migration
     will be done in January 2015.
  2. Bug fixing, enhancement are happing on current branch which
     will be the target v1.0 release.
  3. Work toward next gen version (supports inverted-index) is
     progressing substantially.

    Very good report; an exemplar of how reports should be done.  The
    community seems very active and healthy.  IMO, only items 1 & 2 are
    required for graduation.

--------------------
MRQL

MRQL is a query processing and optimization system for large-scale,
distributed data analysis, built on top of Apache Hadoop, Hama, Spark, and
Flink.

MRQL has been incubating since 2013-03-13.

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

  1. Increase the number of active committers
  2. Increase adoption, expand user community, and increase user list
     activity

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

  The project is not making much progress on the level of increasing the
  number of active committers and expanding the users community.

  This is already being discussed inside the project community and the main
  active committer asked to give the project more few months as he will try
  spreading the word more about the project through some public events

How has the community developed since the last report?

  None

How has the project developed since the last report?

  During the last three month, 12 jira issues were reported, from which 10
  were fixed. Most of these issues were related to MRQL query evaluation in
  Flink mode. Finally, we have set up MRQL on ASF Jenkins, which is a CI
  server that continuously checks the integrity of our builds and validates
  our tests.

--------------------
NiFi

NiFi is a dataflow system based on the concepts of flow-based programming.

NiFi has been incubating since 2014-11-24.

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

  1. Produce an initial release.
  2. Grow our community beyond the initial set of committers.
  3. Establish rhythm for releases, review processes, and document how to
     most effectively bring on new committers.

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

  Nothing we wish to raise at this time.

How has the community developed since the last report?

  The dev mailing list has picked up 20 new e-mails since the last report
  and is now at 62 (commits has grown to 25).

  At the suggestion of the community we've adopted a review-then-commit
  strategy which is designed to among other things help with community
  development.

  We've received several patches from members outside the initial committer
  list including changes which dramatically improved our build process and
  provide new extensions.

How has the project developed since the last report?

  All of our current infrastructure needs are setup and things are working
  really well.  Our focus now is on working towards our first release which
  is 0.0.1 and presently comprised of 85 JIRA issues the vast majority of
  which are resolved.  We've conducted a thorough review of all source files
  to ensure proper license headers/notices/disclaimers are present.  We've
  completed a thorough review and modification of the overall LICENSE and
  NOTICE files in preparation for release.  We've conducted the initial
  podling name search and submitted the ticket for that analysis to be
  verified and confirmed.

Date of last release:

  N/A

When were the last committers or PMC members elected?

  We have not grown the official committer list beyond the initial committer
  list.  Though there are a couple of folks who are committing fairly
  consistently now and a new member to join the dev mailing list that is
  very promising.

--------------------
NPanday

NPanday allows projects using the .NET framework to be built with Apache
Maven.

NPanday has been incubating since 2010-08-13.

Shepherd/Mentor notes:

  P. Taylor Goetz (ptgoetz):

    NPanday has missed the last two reports (last report August 2014). One
    of two mentors are engaged and encouraging the podling to make a final
    release before retiring (last release was on 2011-05-17). However, there
    is little PPMC/Committer involvement with only 2 PPMC members showing
    involvement on the dev@ list in the past year. Also confirmed that a
    report reminder email was received by the dev@ list for each of the last
    missed reporting periods as well at the current period.

    It's clear that mentors past and present have attempted to help the
    NPanday project grow to a viable size -- at least enough to approve a
    release, new Committer/PPMC Member, or even decide to retire -- without
    success.

    The main warning signs appear to be:

    * Inability to reach community consensus (barely 2 acive Committer/PPMC
      Members, making 3 +1s for any vote very difficult)
    * Inability to perform releases
    * Inability to grow the community to a viable size

    The issues listed above do not indicate a lack of mentor involvement,
    but rather a community in decline.

--------------------
ODF Toolkit

Java modules that allow programmatic creation, scanning and manipulation of
OpenDocument Format (ISO/IEC 26300 == ODF) documents

ODF Toolkit has been incubating since 2011-08-01.

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

  1. Grow the community in terms of committers
  2. Have regular releases
  3. Decide if we would like to be a top level project or join an existing
     project, or move to the attic.

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

  No new.

How has the community developed since the last report?

  We have made a release but there has been little activity since then.
  
  We still need to attract more members and publicizing the project in the
  ODF.

  Our validator was used on the ODF Plugfest, ahead a patch was provided by
  a new contributor.

How has the project developed since the last report?

  Update of ODF validator before the ODF Plugfest (London).

  There have been some user issues reported and responded to.

(Tim Chen)
It seems like the project is active in release and code (towards the low activity side).
However the mailing list traffic and engagement has decreased overtime and the
dev list even with jira notifications is still very low traffic.

Shepherd/Mentor notes:

  John D. Ament (johndament):

    Ranger suffered a bit from a renaming issue that came up.  Activity on
    the lists is a little bit lighter since, but I'm sure will bounce back.
    I'm concerned over inability to access the wiki though, sent a note to
    the podling to request proper access.

  The project is waiting for the Software Grant from Univ of Manchester
  Solicitor and Contracts Manager as he needed to retrieve the existing CLAs
  from archive.  He has replied (2015-01-05): "They should arrive back from
  storage this week and we can proceed with the [software grant] transfer"

  Taverna's WSDL-support modified to work with Apache Woden.

  About 45% of code base ready to be migrated (moved to slimmer git layout,
  modified to org.apache.taverna groupId and build).
  TODO: LICENSE and NOTICE plugins for Maven.

  Apache Taverna website live at
  http://taverna.incubator.apache.org/

  Andy Seaborne (andy):
  
    Given the podling has not yet got the software grant on ASF file,
    through no fault of the podling, I suggest keeping reporting Taverna
    monthly.

  Justin Mclean (jmclean):
  
    Off to a good start, with discussions about making builds and assembling
    LICENSE and NOTICE. Mentors (very) active.
