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.
* Community
New IPMC members:
Andrew Bayer
People who left the IPMC:
None
* New Podlings
Groovy
SINGA
* 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 [email protected]
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 âWhy you care about relational algebra (even
though you didnât 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 Calciteâs 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 developersâ
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.
Thatâs why weâre 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 havenât 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.

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.
