--------------------
Guacamole

Guacamole is an enterprise-grade, protocol-agnostic, remote desktop gateway.
Combined with cloud hosting, Guacamole provides an excellent alternative to
traditional desktops. Guacamole aims to make cloud-hosted desktop access
preferable to traditional, local access.

Guacamole has been incubating since 2016-02-10.

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

  1. Finalizing the move to Apache infrastructure
  2. Making the first Guacamole release under the Apache Incubator
  3. Accepting additional committers

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

  The PPMC has had difficulty fully engaging mentors to finish the
  migration of Apache Guacamole to Apache infrastructure and processes.
  Though the project has successfully moved to Apache-hosted git
  repositories, the processes for importing our existing JIRA issues and
  adding our first non-founding committer (Frode Langelo) were stagnated
  until very recently.

How has the community developed since the last report?

  While our community of users continues to grow, this is mainly the
  established pattern of growth that existed prior to acceptance in the
  Apache Incubator. We are expecting this to change once the Apache
  Guacamole website is up, public announcement of the move to the
  Incubator is made, and users of the old SourceForge forums are
  directed to the mailing lists.

How has the project developed since the last report?

  The project has accepted its first committer outside the original
  founding developers, Frode Langelo, and development has moved onto
  Apache-hosted git repositories. Development of new Apache Guacamole
  website is nearing completion.

Date of last release:

  2015-12-18 (0.9.9, prior to Apache Incubator)

When were the last committers or PMC members elected?

  The most recent committer, Frode Langelo, was accepted into the
  project by VOTE on 2016-04-03, with the required ICLA received on
  2016-04-05.

Shepherd/Mentor notes:

  Jean-Baptiste Onofre (jbonofre):
  
    Frode's account should be OK now. For the Jira, the difficulty was that
    the project wanted to import existing Jira content. Not sure it's a good
    idea as bunch of users don't exist in the Apache Jira and there's lot of
    "noise". I would recommend to start by creating the highest priority
    tasks and issues in the Apache Jira.

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

iota

Open source system that enables the orchestration of IoT devices.

iota has been incubating since 2016-01-20.

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

  1. Transitioning code, website and Jira issues to the Apache repositories.
  2. Continuing iota website and code development using the Apache infrastructure.
  3. Building an iota community via a variety of means including presentations at series of conferences beginning with ApacheCon followed by 7x24 Spring Conference, Data center Dynamics and others throughout the summer. We will work with our mentors to find other means of community building.


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

  This project has been slower to start than we anticipated. Why? Based
  on experience in the field with we questioned the scalability of our
  original architecture. We made the difficult decision that we needed a
  more scalable architecture and we on the design of a baseline
  architecture. WE now feel we have a good starting point and with the
  help of the iota community we can move forward with.

Kudu

Kudu is a distributed columnar storage engine built for the Apache Hadoop
ecosystem.

Kudu has been incubating since 2015-12-03.

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

  1. Build a more diverse developer and user community
  2. Migrate our web site under apache.org
  3. Continue to make regular Apache 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?

  The PPMC invited Binglin Chang as a new committer and PPMC member. Binglin
  has continued to increase his involvement and some of his colleagues are
  now becoming more involved as well.

  Since the last report, we had contributions from several new contributors,
  including five new contributors from outside Cloudera (the initial code
  grantor). Of those, two were substantial pieces of new functionality: a
  new sink to ingest data from Apache Flume, and an improved integration
  with Apache Spark. We hope that the authors of these contributions will
  continue to be involved in the community and grow into committers.

  In March, one of our mentors approached the development community with
  some ideas to make the project more approachable for developers. As a
  result of this, we've been working on a few action items:

  1) We started a project blog and have been posting weekly updates on
     development progress as well as more detailed posts on new features or
     project news.  We've heard from community members that this is an easy
     way to track the project without subscribing to high-volume dev lists.

  2) Our dev@ list is currently very noisy with a lot of code review
     comments.  For more casual contributors this can be overwhelming as
     code review is intermingled with higher level project discussions. The
     community discussed the issue and decided to split the code review
     traffic to a new mailing list (currently awaiting infra to create it)

  3) We've started an informal policy of emailing the dev list with a
     heads-up whenever any new larger feature first shows up on gerrit or
     JIRA, to make it easier for people to give input on large items without
     having to see every bug fix or small improvement. For example, whenever
     design discussion starts on a new feature, the contributor sends a
     'heads-up' email to dev@.

  Development activity continues to be healthy. Mailing list traffic for the
  dev list in April and May was similar to the preceding months. Patch
  contribution level is also fairly stable (50-80 commits/month) with lulls
  around releases as people focus on release testing, documentation, etc.

  User mailing list traffic is steadily increasing in quantity and
  diversity: 108 messages in April vs 51 in March, 40 in Feb. April saw 26
  distinct people contribute to the user list discussion vs 15 in Feb.
  Website traffic also indicates growing interest, with April having 30%
  more traffic than Feb.

  In the last two months, Kudu-related talks were delivered in San
  Francisco, San Jose, Beijing, Boston, DC, Detroit, London, and Dublin.
  More talks are scheduled for the upcoming months at ApacheCon Big Data,
  Strata/Hadoop World, Berlin Buzzwords, and various local meetups.

How has the project developed since the last report?

  Since the last report, we've accomplished the following milestones:

  - We released Apache Kudu 0.7.1-incubating on 3/9/2016 to fix a few issues
    found in the 0.7.0 release.
  - We released Apache Kudu 0.8.0-incubating on 4/10/2016 with various new
    features and improvements.

Date of last release:

  April 10, 2016: Apache Kudu 0.8.0-incubating

When were the last committers or PMC members elected?

  - Binglin Chang was added as a committer and PPMC member on April 4, 2016.

Mnemonic

Mnemonic is a Java based non-volatile memory library for in-place structured
data processing and computing.

Mnemonic has been incubating since 2016-03-03.
Mnemonic code was moved into ASF on 3/24.

Various metrics for April are as follows:

  +--------------------------------------------+
  |   Metric                         | counts  |
  +--------------------------------------------+
  | Non Merge Commits                |  16     |
  | Contributors                     |   4     |

  | Pull Requests merged             |   6     |
  | Pull Requests proposed           |   7     |
  +--------------------------------------------+

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

  1. Apache releases: we are preparing 0.1.0 release
  2. Expand and build strong community, keep active dev list discussions,
     adding new contributors
     a. Mnemonic website is up: http://mnemonic.incubator.apache.org/
     b. Mnemonic cwiki is up:
        https://cwiki.apache.org/confluence/display/MNEMONIC/Apache+Mnemonic+Home
  3. Develop new features: We are working in Native computing layer design.

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

  Everything is on track, nothing urgent at this time.

How has the community developed since the last report?

  1. We completed setting up infrastructure. Both project website and cwiki
     are up running. We are working on adding contents and documentation to
     the sites so new contributors and community members can get better view
     of what this project is and how to get involved.
  2. We realized, unlike other application level projects, library (or API)
     projects traditionally had less contributors until certain amount of
     adopters successfully integrated those libraries. We plan to help some
     integrations, such as HBase, Arrow, etc. after our first official code
     release.
  3. We submitted 2 proposals for Strata Hadoop World NYC.
  4. We will present Mnemonic project in upcoming ApacheCon Big Data
     conference on 5/11.

How has the project developed since the last report?

  We are designing the native computing infrastructure, built native
  computing interface code.

  In preparing first official release:

  1. Defined coding guidelines for the project. Reformatted all code based
     on defined coding style.
  2. Added the checkstyle to automate the checking process.
  3. Formalized the names of annotations, classes and methods.
  4. Removed the dependency of property mnemonic.core.version.
  5. Added a new profile for artifacts releasing and signing.
  6. Added release plugin and configuration for releasing.

Date of last release:

  No release yet, working on 0.1.0 release

When were the last committers or PMC members elected?

  No election, since the project is still in early stage of developing.

OpenAz

OpenAz is a project to create tools and libraries to enable the
development of Attribute-based Access Control (ABAC) Systems in a
variety of languages. In general the work is at least consistent with
or actually conforming to the OASIS XACML Standard.

OpenAZ has been incubating since 01-2015.


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

1. Increasing community involvement: We are focusing on getting
information
published on the website to aid the acquisition and orientation of new
contributors,
as well increasing the number of committers, in order to reduce
individual member
workload, reduce reliance on any particular member, and to increase
project velocity. David Ash was voted in as a committer last month.
There are several other committers that may be added in the near future.

2. Merging the source code from AT&T, JP Morgan and Oracle and creating
POMs. AT&T and JP Morgan source code has been merged and POMs created,
it needs uploading into the Apache repository. AT&T and JP Morgan ICLAs were received, but Oracle is taking more time. The IP clearance is on it's way.

3. Get our first release done.

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

None. The efforts to revive the project seem to be paying off and discussions are gaining traction.

How has the community developed since the last report?

Pam Dragosh, David Ash and Ajith Nair are the active committers at this point. The project intends to reboot the PPMC which may include removing
some of the initial commiters who are no longer active. There are, however, several contributors who could be potentially added as committers in the future.

How has the project developed since the last report?

1. Ongoing collective effort to improve project documentation, marketing material for better visbility and adoption.
2. A pending contribution towards PEP implementation is being reviewed and we plan to merge in these changes soon.
3. We are looking into design feedback/comments from Nextlabs - a XACML service provider. We hope to incorporate many of these in the coming weeks.

Date of last release:

N/A

When were the last committers or PMC members elected?

One new committer was elected Tuesday, May 3rd.

  Nothing jumps to mind.

How has the community developed since the last report?

  We have added a new committer and PPMC member, Cazen Lee.  Cazen started
  making valuable contributions almost immediately when Quarks went into
  incubation. The Quarks community is still small, as Quarks has just
  recently incubated, therefore we aim to continue growing our list in the
  near future.


How has the project developed since the last report?

  * According to JIRA, the project has added 59 new issues in April, and 34
    issues have been resolved.
  * On April 13th, the committers hosted an "Introduction to Quarks" webcast
    where they presented a high-level overview of the project and demonstrated
    how to write, monitor and debug Quarks applications.

Date of last release:

  Quarks is still new, so we haven't created an Apache release as of yet.

When were the last committers or PMC members elected?

  In April we added a new committer and PPMC member, Cazen Lee.

     from different organizations, electing the most dedicated as additional
     committers.
  2. Demonstrate open collaboration and decision making among contributors,
     committers and the PPMC in The Apache Way
  3. Create one or more usable official releases of Apache Quickstep.

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

  None.

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 continue to see regular interaction with users who are trying out
  Apache Slider (incubating). Questions range from introductory "I'm
  trying to do $x" to bug reports "I did $a and encountered an issue $b".
  The committers try their best to keep people involved and steer them
  toward contributions. The strong majority of contributions continue to
  come from existing podling members.

How has the project developed since the last report?

  The IP clearance for the Apache Kafka Slider "app-package" process
  was addressed (after discussion on general@i.a.o) and this codebase was
  merged in. This was a great contribution by a few external developers
  and very much appreciated.

  Work continues on "phase 2" of some long-term work to include support
  for running Docker containers in Slider. The intent behind this work is
  that we will make it easier for (prospective) users to build
  applications that can run on Slider. There is a tentative patch on
  SLIDER-906 and some related documentation updates.

  We have agreed upon a next release (0.91) happening in May, but have
  not made any significant progress towards that release yet.

  We had a discussion put forth about the future of Slider by a podling
  member. At the inception of Slider, Apache Hadoop's YARN was not ready
  to support long-lived services "natively". While Slider has been in
  incubation, YARN has continued to grow towards treating these services
  natively, partly as a result of requirements necessary of Slider to
  work. As such, we discussed whether it would make sense to ask the YARN
  project if they would be interesting in combining efforts, moving the
  core of Slider into YARN itself. The Slider community reacted
  positively, noting that YARN is likely a better long-term home for the
  core of Slider; however, there were a few points raised that would need
  to be addressed before any action was actually taken. The mail discussion
  can be found at https://s.apache.org/3ywX

SystemML

SystemML provides declarative large-scale machine learning (ML) that aims at
flexible specification of ML algorithms and automatic generation of hybrid
runtime plans ranging from single node, in-memory computations, to
distributed computations running on Apache Hadoop MapReduce and Apache
Spark.

SystemML has been incubating since 2015-11-02.

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

  - Grow SystemML community: increase mailing list activity,
    increase adoption of SystemML for scalable machine learning, encourage
    data scientists to adopt DML and PyDML algorithm scripts, respond to
    user feedback to ensure SystemML meets the requirements of real-world
    situations, write papers, and present talks about SystemML.
  - Continue to produce releases.
  - Increase the diversity of our project's contributors and committers.

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 mailing list from February through April had 199 messages involving
  topics such as algorithms, DML functionality, usability, and bug fixes. In
  addition, we have had many discussions on our JIRA site and in pull
  request conversations. Fred Reiss presented at Spark Summit East on
  February 17 about SystemML internals. Berthold Reinwald spoke at the Spark
  Technology Center on March 9 about scalable machine learning with
  SystemML. Niketan Pansare spoke on April 28 at Datapalooza in Austin and
  on April 29 at Rice University about declarative machine learning at scale
  with SystemML. Researchers in Germany are working to add Flink as an
  additional SystemML backend. On GitHub, the project has been starred 267
  times and forked 92 times. We have gained two new contributors since
  February 1st.

How has the project developed since the last report?

  We produced our first Apache release, version 0.9.0-incubating. Numerous
  additions have been made to the project, including core functionality,
  usability improvements, and documentation. The project has had 204 commits
  since February 1. In the same time frame, 155 new issues have been

TinkerPop has been incubating since 2015-01-16.

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

  The outstanding issues have been addressed.

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

  Nothing at this time.

How has the community developed since the last report?

  We have 4 new committers: Ketrina Yim, Pieter Martin, Jean-Baptiste Musso,
  and Michael Pollmeier

How has the project developed since the last report?

  Since the last status report, 172 new JIRA issues have been created and
  126 have been resolved.  Open discussions of the project related
  activities and decisions continue on the TinkerPop dev mailing list.  The
  committer count has been growing and various other TinkerPop community
  members have shown an increased amount of participation on tickets and in
  discussion.  Excellent work is being performed by a variety of folks on a
  consistent basis that has resulted in two releases since the last report.

  Over the past few months, work was performed to stand up a new DataStax
  hosted website, Planet TinkerPop.  This raised concerns in the Apache
  community and it was determined that the best course of action was to
  request that Planet TinkerPop be taken down, and some of the
  vendor-neutral TinkerPop content be donated to TinkerPop for usage on the
  TinkerPop incubator site.  Efforts were made to avoid running afoul of
  Apache guidelines prior to the Planet TinkerPop launch, but the PPMC did
  not have a complete understanding of Apache brand management expectations.
  Over the past weeks, the transition of DataStax donated content to the
  TinkerPop site has been completed.  In the process, the PPMC has received
  guidance and clarification from mentors and the wider Apache community.
  We feel that the Apache TinkerPop site is stronger now than ever and will
  continue to serve as a great vendor neutral resource going forward. The
  lessons learned throughout this process will serve the TinkerPop PPMC well
  going forward.

  Since the last status report, 166 new JIRA issues have been created and
  127 have been resolved.  Open discussions of project related activities
  and decisions continue on the TinkerPop dev mailing list.

Date of last release(s):

  * 2016-04-21 - Apache TinkerPop 3.1.2
  * 2016-04-21 - Apache TinkerPop 3.2.0
