Incubator PMC report for April 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 40 podlings currently in incubation. There is another
climate project in discussion for incubation which is an interesting
continuation of the nascent trend of academic projects coming to
Apache. This may be a singleton due to Chris Mattman's efforts, but it
would be an interesting development if it gathers momentum.  

There is a new ASFIncubator twitter entity. It has little activity so
far, but has had a lot of followers jump on after Sally's announcement
on @ASF.

Datafu and ODF Toolkit are showing very low activity. This isn't
necessarily a serious problem yet, but may be a leading
indicator. Wave has previously had a warning, but may be doing a
little better.

    just barely beginning)

* Graduations

    None

* Releases

  The following releases were made since the last Incubator report:

    2015-03-03 apache-lens-2.0.1-beta-incubating
    2015-03-16 nifi-0.0.2-incubating
    2015-03-23 apache-calcite-1.1.0-incubating
    2015-03-24 incubator-ignite-1.0.0-rc3
    2015-03-27 slider-0.70.1-incubating

* IP Clearance

  Usergrid is working feverishly to finish up their IP Clearance.
  Updated SGA sent to secretary@a.o

  CommonsRDF SGA filed 2015-03-27.

  Zeppelin SGA submitted and acknowledged on 2015-03-20.

* Legal / Trademarks

  The old debate about how to submit SGAs for ALv2 projects with huge
  numbers of copyright holders reappeared with Groovy's SGA.  In the end,
  the SGA was signed by a single community member.

  Ambiguity around Legal Policy language on when optional GPL library
  dependencies are permitted caused confusion.

* Infrastructure

  The "Marvin" report reminders have not run in a timely manner for podlings
  for 4 months in a row.  A dedicated Incubator-specific replacement is
  being contemplated.

* Miscellaneous

  An official Twitter account for the Incubator was initialized but has not
  yet been used.  Access will be maintained via TweetDeck.

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. Get SGA signed from UCI and others.
  2. Code drop and start actively using lists.
  3. Do an Apache release.

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

  No, still getting started.

How has the community developed since the last report?

  Account setup is mostly done and code repositories are in place. Right now
  working mostly on the SGA to do the code drop.

How has the project developed since the last report?

  Account and other infrastructure setup mostly done.
  SGA and code drop still open.

Date of last release:

  No Releases yet.

When were the last committers or PMC members elected?

  No elected PMC and/or committers

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 March, there were 159 messages on dev@, 41 commits, 52 issues
  created, 37 issues resolved by 8 contributors.

  Julian Hyde gave a talk “Why you care about relational algebra (even
  though you didn’t know it)" about Calcite at Enterprise Data World in
  March. He also spoke at a Phoenix meet-up in San Francisco about
  Phoenix-Calcite integration.

  Collaborations are under way with other Apache projects:
   * Phoenix is going to use Calcite for SQL parsing and planning; and a
     separate project is using Calcite’s Avatica component to build a remote
     JDBC driver.
   * Added support for parsing/validating streaming SQL and collaborating
     with the Samza project on adding streaming SQL to Samza.
   * Collaboration with Hive and Drill continues.

How has the project developed since the last report?

  We completed our milestone 1.0 release, continued our monthly release
  tempo with release 1.1, and are preparing 1.2.

Date of last release:

  2015-03-23

When were the last committers or PMC members elected?

  December 2014.

--------------------
CommonsRDF


Commons RDF is a set of interfaces and classes for RDF 1.1 concepts and
behaviours.  The commons-rdf-api module defines interfaces and testing
harness.  The commons-rdf-simple module provides a basic reference
implementation to exercise the test harness and clarify API contracts.

CommonsRDF has been incubating since 2015-03-06.

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

  1. Grow the CommonsRDF Community such that we can progress
     towards gradution
  2. Further engage the podling with the nuances of the Apache
     Incubation process
  3. Drive towards the first incubating release

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

  A SGA was recently filed with secretary@ and the CommonsRDF codebase now
  resides at the ASF with the canonical source residing at
  https://git-wip-us.apache.org/repos/asf?p=incubator-commonsrdf.git

  Project is not yet decided on goal of TLP or Commons component - but still
  aiming at the Commons component.

How has the community developed since the last report?

  There have been no new committers, however the overwhelming majority of
  project-related development conversation is already taking place on the
  Apache lists.

How has the project developed since the last report?

  CommonsRDF very recently joined the Apache Incubator. Bootstrapping and
  migration have quickly progressed (mailing lists, git, Jira) and the
  initial committer community is transitioning very well into the Apache
  incubator ecosystem.

  Web site remains to be sorted - evaluating technologies (considering
  INFRA's proposed CMS deprecation).

Date of last release:

  XXXX-XX-XX

When were the last committers or PMC members elected?

  N/A Commons RDF has only just joined the Apache Incubator.

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

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

  1. All the ICLA of all the PMC / Committers have been sent.
     Most Apache accounts have already been created.
  2. On behalf of the whole Groovy development team and the community,
     Guillaume Laforge signed and scanned the SGA, and sent it to Secretary
     on April 1st.
  3. We've communicated to the historical mailing-lists about the new lists,
     encouraging subscribers to join the new ones. The JIRA migration should
     be taking place over the week-end, and we'll also communicate with our
     community about that change. And last but not least, we need the Git
     repository to be created and import our current sources from Github.

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

  No, just getting started.

How has the community developed since the last report?

  Currently, the pretty large Groovy community is happy about the move into
  the ASF, but continues to be centered around our old infrastructure.
  That’s why we’re going to start attracting the community towards our new
  lists, to get them involved in this new era for the project.

How has the project developed since the last report?

  No last report, as this is the first!

Date of last release:

  We did a last non-Apache release as the vote for incubation was still
  ongoing, but we haven’t yet planned the next release dates.

When were the last committers or PMC members elected?

  No new elected PMC or committers.

  Bertrand Delacretaz:

    Thanks Guillaume for taking the lead on this!

  Emmanuel Lecharny:

    Quite a good start for a podling... Even the user mailing list starts to
    be active ! Waiting for the JIRA migration this week-end, and the code
    migration asap, then the podling will be almost fully setup, as soon as
    the web site will be available. Great work by the Groovy fellows, and
    the Infra peeps !

  John D. Ament:

     Project seems to be going well initially, doing the expected up front
     house keeping required considering the largish size of the code base.
     I would expect email volume to pick up quickly as the Codehaus services
     begin to shutdown.

--------------------
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:

  1. Grow user and developer community and add more committers
  2. Document all features and do one more release

Myriad enables co-existence of Apache Hadoop YARN and Apache Mesos together
on the same cluster and allows dynamic resource allocations across both
Hadoop and other applications running on the same physical data center
infrastructure.

Myriad has been incubating since 2015-03-01.

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

  1. Get ebay to donate the code to ASF. Ebay is willing and has done this
     before. The process is started, but will take time.
  2. Get ICLAs from all committers and give them Apache accounts and karma.
  3. Integrate with Apache infrastructure and make our first release.

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

  None. Just getting started.

How has the community developed since the last report?

  First report. Now we have mailing lists and discussions have started on
  dev@. In addition to committers/contributors from the 3 initial
  organizations (ebay, MapR, Mesosphere), we have 5 more contributors from
  at least two different organizations.

  Gave presentations at Strata/Hadoop World and the March Bay Area Mesos
  Users Group and London MUG meetups. Upcoming presentations at ApacheCon,
  Data Science MD, and East Bay Big Data Group.

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. Get ICLA’s from all the committers. So far AT&T and JP Morgan have done,
 but Oracle is taking more time.
2. Merging the source code from AT&T, JP Morgan and Oracle and creating 
 POM’s. AT&T and JP Morgan source code has been merged and POM’s created,
 it needs uploading into the Apache repository.
3. Get our first release done.

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

Shepherd/Mentor notes:

  Daniel Gruno:

    While I am happy that a new committer has been invited to the group, it
    seems that the project is struggling with the how-to of the ASF. We need
    to further educate the PPMC on our procedures.

--------------------
Usergrid

Usergrid is Backend-as-a-Service (BaaS) composed of an integrated database
(Cassandra), application layer and client tier with SDKs for developers.

Usergrid has been incubating since 2013-10-03.

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

  1. Continue to grow the Usergrid Incubating Community
  2. Clarify the SGA for Apache Usergrid Incubating codebase
  3. Drive towards another Usergrid incubating release

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

  The Usergrid community has been working to clarify the status of the SGA
  for the Usergrid codebase. The original SGA listed a GitHub repo that did
  not include all of the source code that Apigee intended to grant. We
  are preparing a new SGA that will cover all code that is currently part of
  the project.

How has the community developed since the last report?

  In short, the Usergrid incubating community is healthy with loads of
  mailing list and development traffic from a growing community. Usergrid
  continues to see new community members making themselves known on the
  mailing lists.

How has the project developed since the last report?

  Development is very dynamic. The codebase is being actively developed with
  correspondence taking place on the Usergrid JIRA instance. The processes
  and workflows for development are pretty solid now.

--------------------
Wave

A wave is a hosted, live, concurrent data structure for rich communication.
It can be used like email, chat, or a document.

Wave has been incubating since 2010-12-04.

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

  1. Wave is very close to making its first release.  This is the top
     priority.
  2. The project needs to determine what the next few technical goals are.
  3. The project needs to attract more developers and users.

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

  None at this time.

How has the community developed since the last report?

  The community has been slow to develop.  There are still many people
  downloading and using the software, we have seen several bug reports and
  questions, but there has not been much contribution by new members.

How has the project developed since the last report?

  The code for the release has largely been finalized.  We believe that
  major legal and technical issues have been overcome.  Only a few finals
  steps remain. The project believes that we are finally ready to make a
  release.

Date of last release:

  N/A

When were the last committers or PMC members elected?

  July 2014

Shepherd/Mentor notes:

  Christian Grobmeier:

    The mentors have missed to sign this report last time. For that reason I
    am adding it again. Since last month there was some discussion on how to
    prevent the project going to the attic.

  Upayavira:

    We have received a GSoC application, and a committer has accepted the
    role of mentor. The task involves simplification of the codebase which
    will make it more accessible to others, hopefully facilitating greater
    involvement, as it seems the greatest impediment to Wave is the
    (over)complexity of its codebase.
