    "clearly identifiable non-release artifacts" for Geode, which has not
    yet made an incubating release but publishes nightly builds on
    DockerHub.

  * A proposal for incubating Pistachio, a fault-tolerant low latency
    distributed storage system which originated at Yahoo, is being
    discussed.

    functionality to whimsy.

  * OpenAZ reported, but failed to get any mentor sign-offs.  I have 
    withheld that report but will insert it as a late change if it
    gets the necessary sign-offs quickly. If not, we will include
    it next month with proper sign-off.

AsterixDB

Apache AsterixDB is a scalable big data management system (BDMS) that
provides storage, management, and query capabilities for large collections
of semi- structured data.

AsterixDB has been incubating since 2015-02-28.

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

  1. Do an Apache release.
  2. Migrate issues from Google Code
  3. Grow community

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

  No, moving steadily.

How has the community developed since the last report?

  A little more outside interest in the project.

How has the project developed since the last report?

  - JSON file for Google code issues imported into AsterixDB to use
    AsterixDB for transformation and migration
  - Draft for a new version of website available
  - Development is ongoing

Date of last release:

  No Releases yet.

When were the last committers or PMC members elected?

  No new elected PPMC and/or committers since entering incubator.

--------------------
Climate Model Diagnostic Analyzer

CMDA provides web services for multi-aspect physics-based and phenomenon-
oriented climate model performance evaluation and diagnosis through the
comprehensive and synergistic use of multiple observational data, reanalysis
data, and model outputs.

Climate Model Diagnostic Analyzer has been incubating since 2015-05-08.

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

  1. Get all initial committers/IPMCers ICLA filed
  2. Get all initial committers/IPMCers on the mailing lists
  3. Get code into ASF repo

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?

  No change, see below.

How has the project developed since the last report?

  CMDA is still in spin up mode. 4 out 7 initial members have ICLAs on file.
  Mentors are working with the rest to move this forward. The project has
  JIRA and git setup. Code and development still need to be moved. The
  mailing lists are setup but not all of the initial members have
  registered.  Again, mentors are working to help move this forward.

Date of last release:

  None yet

When were the last committers or PMC members elected?

  None yet

--------------------
Geode

Geode is a data management platform that provides real-time, consistent
access to data-intensive applications throughout widely distributed cloud
architectures.

Geode has been incubating since 2015-04-27.

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

  1. Expanding the community to include contributors and committers outside
     of Pivotal
  2. Execute and manage the project according to governance model required
     by the "Apache Way"
  3. Have our first Apache (incubating) release (currently blocked on us
     solving JGroups licensing issues)

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

  The issue of publishing the nightly build to DockerHub was brought up so
  we solicited IPMC feedback. There was a great discussion thread and we're
  now taking care of actionable feedback with an ETA within a week or so.

How has the community developed since the last report?

  Mailing list activity in June: 208 emails on dev, 28 emails on user. Dev
  currently has 116 subscribers, user has 96. Topics range from Geode
  features and changes to Apache Way and policies affecting our project.

  There are 50 open issues on JIRA, 8 In Progress, 14 Resolved or Closed

Shepherd/Mentor notes:

  John D. Ament:
  
    The JGroups licensing issue caught me off guard.  Based on what I read
    about it, it's purely a technical issue and not licensing related
    (though triggered by licensing).  Based on the documentation heavy
    approach I'm concerned that this could be an issue for potential
    contributors (needing to create designs up front for issues).  Code
    changes seem to be going slow, but the fact that they already have a
    great website and nice logo is a good sign for the podling.

--------------------
Groovy

Apache Groovy is a multi-faceted programming language for the Java platform.
Groovy is a powerful, optionally typed and dynamic language, with static-
typing and static compilation capabilities, aimed at multiplying developers’
productivity thanks to a concise, familiar and easy to learn syntax. It
integrates smoothly with any Java program, and immediately delivers to your
application powerful features, including scripting capabilities, Domain-
Specific Language authoring, runtime and compile-time meta-programming and
functional programming.

Groovy has been incubating since 2015-03-24

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

  The biggest issue we've had to handle was with a subset of our
  documentation (guides written in asciidoc). Parts of the documentation
  have already always been licensed under ASL 2 but the text from asciidoc
  guides has recently had a Creative Commons Share Alike 3.0 license. To
  avoid a potential grey area over whether the software grant implicitly
  changed the licensing terms to ASL 2, we contacted all contributors
  (GROOVY-7470) and they all approved an explicit change to ASL 2 and all
  relevant artifacts have been modified to reflect that change.

  Lack of ASF (incubating) release

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

  No particular issue right now.

How has the community developed since the last report?

  The new Groovy mailing-lists at Apache are doing fine, and it seems a
  large portion of our community have already followed our move here.

  The project has received 19 pull requests this past month,
  and the team has managed to handle and integrate 17 of them.

  This shows an active community is there to contribute to the project.
  Furthermore, since the move to Apache,
  we're also seeing contributions from new developers
  that were not known to us before.

  Groovy committers have also contributed to other Apache projects including
  RAT (contributions of fixes that we needed) and evaluations of Commons CLI
  and Ant release candidates using the Groovy test suites.

How has the project developed since the last report?

  Ongoing incremental improvements and bug fixes.

Date of last release:

  No release yet, but progress has been made to make our build process
  comply with Apache rules, in particular with RAT.  We've moved our build
  to use the Gradle RAT plugin (which incidentally we have contributed fixes
  to).  We attempted a release that had to be cancelled, as we had still
  some issues around the usage of JARs in our test resources which have now
  been resolved.

When were the last committers or PMC members elected?

  Russel Winder joined as a new committer on the team.

  Another person signed the ICLA, so we should have another one joining soon
  too.

Shepherd/Mentor notes:

  Emmanuel Lecharny:

    Those guys are really doing a good job ! The project is active, new
    committers are being added, they are respectfully following the rules,
    and when they are not complying by mistake, they fix their way of doing
    things. As a mentor, it's a pleasure !

--------------------
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.

Shepherd/Mentor notes:

  Justin Mclean:
  
    Did not report this month. Last report (March) project was considering
    retiring. There has been no real activity on mailing list and given lack
    of progress on releases I think we should ask the PMC to consider
    retiring the project.

--------------------
Lens

Lens is a platform that enables multi-dimensional queries in a unified way
over datasets stored in multiple warehouses. Lens integrates Apache Hive
with other data warehouses by tiering them together to form logical data
cubes.

Lens has been incubating since 2014-10-10.

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

  We had discussion about "where is Lens with respect to graduation" on dev
  mailing list. Most of PPMC and mentors feel that Lens is ready to
  graduate.  http://s.apache.org/rYP

  We intend to start preparing the graduation vote, following the
  discussion.

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?

  There have been many new contributors showing interest and participating
  in discussion on dev mailing list and Our user mailing list is growing
  with usage questions.
  
  Apache Lens talk is presented at ApacheCon NA and GIDS, India in April,
  2015 and Hadoop Summit, NA in June, 2015.  Lens meetup with hackathon is
  planned on 11th July.

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:

     @general and License issue.
  2. Add roadmap page on wiki
  3. Initiate graduation discussion with community and address any concerns
     raised

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

  Community is working on making 1.5.1 release to fix the previous release
  issue. Most of the other issues raised during the last report have been
  resolved:

  1. Updated incubator Sentry page: Update news,committers list and status
     reports sections
  2. Fixed MarkMail link in sentry mailing_lists page
  3. Added Roles and responsibilities of committers and PPMC:
     http://s.apache.org/xPU
  4. Updates to "How to release”

  had 115 messages on dev list last month. (Got number from
  http://markmail.org/list/org.apache.sentry.dev)

How has the project developed since the last report?

  There were multiple bug fixes and some new feature work has started. About
  30 issues were created and about 20 resolved(Numbers from jira).

Date of last release:

  2014-08-18

When were the last committers or PMC members elected?

Shepherd/Mentor notes:

  P. Taylor Goetz:
    
    Mentors are engaged and have raised a number of issues for the project to address
    prior to graduation. The Sentry community seems to be actively working on addressing
    those issues. One issue (raised by mentor David Nalley) that seems yet to be addressed
    is a lack of on-list discussions regarding project direction.

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