  N/A

How has the community developed since the last report?

  A new community member has mentioned development of a branch which _may_
  have the potential to drive the project in a different direction.  Commons
  RDF IPMC members are continuing conversation on the topic.  Additionally
  there is recent discussion of how Commons RDF can be used within Apache
  Jena. Jena is one of the key consumer communities Commons RDF aims to
  target within the scope of addressing #3 above.

--------------------
Corinthia

Corinthia is a toolkit/application for converting between and editing common
office file formats, with an initial focus on word processing. It is
designed to cater for multiple classes of platforms - desktop, web, and
mobile - and relies heavily on web technologies such as HTML, CSS, and
JavaScript for representing and manipulating documents. The toolkit is
small, portable, and flexible, with minimal dependencies. The target
audience is developers wishing to include office viewing, conversion, and
editing functionality into their applications.

Corinthia has been incubating since 2014-12-08.

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

  1. Solve the community crisis and avoid a break
  2. 
  3. 

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

  The community is experiencing a major breakdown. The mentors have accessed
  the situation including several attempts to stop the breakdown without
  success. IPMC have been informed with a suggestion which are being
  considered.

  It is to be expected that several core developers will leave the project
  in a very short term unless a solution is found.

How has the community developed since the last report?

  We are proud that we have managed to make our first release.
 
How has the project developed since the last report?

  Added support for 32/64bit windows.

  Made the setup of a build environment a lot easier, a PPMC provide all
  third party libraries prebuilt.

  A long discussion about licenses lead to major difficulties in deciding
  whether and how to proceed with one of the project’s two main
  components, an end-user editing app. As a result this development is
  being redirected.
 
  Our buildbot setup is slowly taking shape, this is important since it will
  allow a nightly build as well as a nightly test.

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

  1. IP clearance
  2. Move to ASF infrastructure, especially the code repository
  3. Finding contributors

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?

  We are still in early stage of incubation (like source code was
  only imported recently), so not much is happening inside ASF yet.
  One new contributor has found us through ASF.

How has the project developed since the last report?

  GitHub import was done, we are starting the IP clearance process.
  (On GitHub the project was highly active.)

    Activity has been extremely low on the podling, pinged them to see how
    they were doing, received a quick response.  It's always sad to see a
    podling choose to retire, but it's a valid resolution in this case.

--------------------
log4cxx2

Logging for C++

  Not grown. However, the project aims to become a sub project of Apache
  Logging again. Community growth is not much a matter for this podling, as
  long as there are a few active contributors.

How has the project developed since the last report?

  Not at all: There's no public development and it seems there's currently
  only one originally incubating community member left. Though some support
  is given and bugs are tracked.

    The podling is not very active but is thriving.  There appears to be a
    tight community behind it.  It may help the podling to bring in some new
    mentors to keep things moving.  Potential new contributors have begun
    discussing on the mailing lists, so we'll see how they grow.

SAMOA

SAMOA provides a collection of distributed streaming algorithms for the most
common data mining and machine learning tasks such as classification,
clustering, and regression, as well as programming abstractions to develop
new algorithms that run on top of distributed stream processing engines
(DSPEs).  It features a pluggable architecture that allows it to run on
several DSPEs such as Apache Flink, Apache Storm, Apache S4, and Apache
Samza.

SAMOA has been incubating since 2014-12-15.

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

  1. Grow the community
  2. Elect new PMC members
  3. Following up our first release with further 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?

  Mailing list activity (June-July-August 2015):

  * @dev     225 messages

  Jira issues backlog (June-July-August 2015):

  * Created:  10
  * Resolved: 5

  Our main goal is still to grow the community, which is still pretty small.
  We are doing a large amount of dissemination work in conferences and
  events to promote SAMOA.

  We have had contributions from outside the PMC.  In particular, we have
  been collaborating with the Apache Flink community.

How has the project developed since the last report?

  Main developments:

  * First release 0.3.0 in July.
  * Cleanup of codebase to ease adoption by new contributors.

  We should increase the rate of technical contribution to the project and
  move to less incremental ones.

     SIGMOD15 (Melbourne), VLDB15 (Hawaii), and a local workshop on deep
     learning in Singapore, to extend the reach of the project to developers
     from other institutions and countries.   

  3. There are new developers contributing to the code base. 

How has the project developed since the last report?

  1. Implementation of the features included in the first release was
     completed. Particularly, we added contrastive divergence algorithm for
     training RBM models. Checkpointing and restoring are also implemented.
 
  2. Code review is completed for 3/4 of the code. We also tuned and
     optimised the code to improve efficiency and scalability. 
 
  3. User documents are added at
     http://www.comp.nus.edu.sg/~dbsystem/singa//docs.html. We are moving

Slider

Slider is a collection of tools and technologies to package, deploy, and
manage long running applications on Apache Hadoop YARN clusters.

Slider has been incubating since 2014-04-29.

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

  1. Getting more external users
  2. Getting more diverse set of developers
  3. Getting more diverse set of committers/PMC

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?

  We are seeing a lot of traction in the community, over the improvement in
  deployment and management of applications using Slider. Good number of
  emails are pouring in the dev list, primarily on creation of Slider
  packages for newer applications and willingness to contribute code. Few
  presentations and meetups were organized by the community, socializing
  their Slider-ized applications.  Occasional patches were submitted and a
  number of features added to the recent releases were driven by end-user
  needs. We still have to get those people into long term coding, and then
  bring them in to the committer group. 

How has the project developed since the last report?

  We released slider-0.80.0-incubating in May with 64 JIRAs resolved. It was
  one of Slider's most important release, with several critical business
  application features like rolling upgrade, co-processor support for
  dynamic addition of libraries, and support for Docker containers.

  We've been debating when to switch from Hadoop 2.6+ support to 2.7.1+
  only.  Given how Slider has always tended to push much of the YARN
  services work, it's time to pick up on the changes they've put in.
