  The Incubator continues to use discretion when enforcing release policy.

  * Numerous releases have been approved despite having an out of date
    copyright year in the NOTICE file.  Fixing for the next release has been
    considered a sufficient remedy.
  * The REEF release was approved with an incomplete incubation
    disclaimer in README (there was also a disclaimer on the podling
    website).

* IP Clearance

  CouchDB Mango -- IBM Corporation have built a MongoDB API Layer for
  CouchDB and are donating it to the CouchDB project. This consists of of a
  module that exposes a set of actions that are similar to what MongoDB
  exposes.

* Legal / Trademarks

  Taverna successfully cleared its name search.

--------------------
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. Discuss and decide on a medium-term roadmap
  2. Grow the community
  3. Finalize source structure change (easy access for new developers)

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

  none

Shepherd/Mentor notes:

  John D. Ament (johndament):

    Still a new podling, growing pretty well though.  Small number of
    participants that may need further growth to be viable long term.

--------------------
Droids

Droids aims to be an intelligent standalone robot framework that allows to
create and extend existing droids (robots).

Droids has been incubating since 2008-10-09.

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

  1. Activity
  2. Name Search

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

  None.

  We need to continue the name search. Branding has replied to the issue and
  provided additional searches that need to performed. It is hoped that
  these can be finished in the new couple weeks.

How has the community developed since the last report?

  No change.

How has the project developed since the last report?

--------------------
HTrace

HTrace is a tracing framework intended for use with distributed systems
written in java.

HTrace has been incubating since 2014-11.

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

  1. Continue to grow the HTrace community
  2. Continue to develop and release stable HTrace incubating artifacts
  3. Continue to explore the integration of the HTrace framework into other
     Apache products

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

  Around January 20th HTrace successfully made the first release whilst in
  the Apache Incubator.  This was the outcomes of no-less than 10 release
  candidates and as many VOTE's.  In all every release candidate was very
  well managed with HTrace community providing excellent feedback to the
  release manager. Rather than then entire 10 release candidate exercise
  being a pain point for the community, it appears to have strengthened all
  involved. Well done HTrace.

How has the community developed since the last report?

  It is early incubating days for HTrace. The community has attracted in
  particular a new member who is doing a sterling job on a new UI for
  HTrace. Additionally it should be noted that the entire
  htrace-3.1.0-incubating release effort has certainly brought the existing
  community on leaps and bounds.

How has the project developed since the last report?

  The project has progressed significantly. In fact, it was highlighted on
  at least one occasion that documentation supporting a release candidate
  should be further clarified/improved due to the dynamic progressive nature
  of the HTrace codebase. As an early incubating project this is accepted as
  a positive move.

Shepherd/Mentor notes:

  Matthew B. Franklin (mfranklin):

    Lot's of code is being committed to the project, but mostly by a couple of
    developers.  There also does not appear to be much discussion on the list
    in last period, likely  due to the low number of developers.

    I recommend the podling focus on increasing the size and participation of
    the community as one of the issues to address prior to graduation.

--------------------
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. Building a diverse developer and user community
  2. Achieving broader adoption of the existing code and slider-deployable
     applications (examples: HBase, Accumulo)
  3. Making slider better at deploying other applications, so improving
     takeup.

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're getting more people on the mailing list asking for improvements;
  anyone with a patch is being helped to get it in. That builds up the
  developer base and is intended to move it from a single team to one
  distributed community development.  As we grow, we're proposing moving
  from a single slider developer list to:a separate user mailing list, and a
  third list for the JIRA/svn/git events. This will focus the developer list
  around discussion, with a user list to help build that user community. We
  do of course expect developers to also subscribe to the user list.

How has the project developed since the last report?

  We've done a source-only release in November, 0.60.0-incubating, in sync
  with features in Hadoop 2.6, with a binary packing version,
  0.61.0-incubating has just been voted for release (3-feb 2015); the
  incubator vote is now pending. It was nice to see tests and a vote on the
  release from an external user & patch submitter -community engagement
  includes things like this.

  A new release, 0.70 is being created with the release planned
  mid-February. This will include improved features and fixes —especially
  those reported by users of the 0.60 release. For example, one group wanted
  short-lived applications on secure clusters, instances where Slider does
  not need to worry about keytab expiry. Another need of people writing
  slider-deployed applications was for a placement policy of "only ever ask
  for component placement where instances were before"; this is needed for
  Kafka.

  Some of the feature requests are quite "ambitious", especially those
  related to deployed components providing information back to the Web/REST
  GUIs, and extending the configuration model to include: more
  on-target-machine configuration, per-instance configuration and better
  strategies for placing components within the YARN cluster. These requests
  do represent real needs; even if they are long term features we need to
  think about how to get there.

  We're discussing supplementing the dev@ mailing list with issues@ and
  user@ lists; the issues list for all JIRA updates -creation and completion
  would still go to the developer list. This is to separate the noise of
  JIRA-centric development from a developer list focused on broader
  application features and building a community. We don't want to scare
  people off from too much JIRA, or worse: lose what they have to say in the
  emails. Similarly, the user@ list is where we want to encourage users. The
  original rationale for a single list was "one single community
  discussion", but it's not clear its worked out that way.

Date of last release:

  2014-11: Slider 0.60 (source, against Hadoop 2.6)
  2015-02: (vote in progress) Slider 0.61.0 (binary, against Hadoop 2.6)

Shepherd/Mentor notes:

  Andy Seaborne (andy):

    Taverna remained on the monthly reporting cycle because the Software
    Grant had not been received.  If it arrives as per schedule, Taverna can
    go onto its normal reporting cycle.

    Podling is active, 2 mentors participating on the mailing lists.

TinkerPop

TinkerPop is a graph computing framework written in Java

TinkerPop has been incubating since 2015-01-16.

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

  1. Software grant needs to be approved.
  2. Migration to Apache infrastructure.
  3. Getting our team comfortable with the new environment.

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

  We have been hanging on the software grant approval for a week now. Be
  good to get that knocked out so we can move forward.

  John D. Ament (johndament):

    Links to mailing lists are still pointing to google, appears to be on
    purpose.  By doing so keeps the mailing lists active from original state.
