Any23 is defined as a Java library, a Web service and a set of command line tools to extract and validate structured data in RDF format from a variety of Web documents and markup formats. Any23 is what it is informally named an RDF Distiller.

A list of the three most important issues to address in the move towards graduation

   1. Port Any23 code to ASF infrastructure and update license headers
   2. Develop a strong community with organizational diversity and with strong connections to other relevant ASF communities.
   3. At least one Any23 incubating release

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

Yes, all of the code has been ported from Google Code to the ASF. Thanks to Daniel Shahaf and Michele Mostarda for 
leading the charge here.

How has the community developed since the last report?

All ASF karma has been granted on the repository, and we've received a few JIRA issues, but not from outside
the core set of PPMC members as of yet. The team needs to respond to Paolo Castagna's points regarding RDF
frameworks and collaboration, and will hopefully do so this month. 

How has the project developed since the last report?

Any23 was voted into the Incubator by the IPMC on October 1, 2011.

We have Jenkins CI builds going thanks to Lewis John McGibbney, code up and running at the ASF thanks to Michele
and to Daniel, so we're all set to really get kicking!

Celix is an implementation of the OSGi Specification in C.

Celix entered incubation on November 2, 2010.

Over the last few months lots of work has been put into integrating APR and updating the Celix code base to the proposed code style. This code style has partially been documented on [1]. Also some effort has been put into updating the source for Visual Studio, even though not yet finished some interesting and helpful patches where submitted and applied.

In Oktober an event was held to create more awareness for services, OSGi and Celix in the Dutch embedded community. The attendance was great, and a follow-up will be planned. Also, in November a talk was given at the ApacheCon.

As listed below, one of the most important issues is the slow growth of the Celix community. With the current discussion about poddlings and how long a poddling is in the incubator, we are discussing a plan how we can move to a more diverse community and be able to graduate. This plan will be included in the next board report.

Most important issues are:

* Improve robustness (APR, error handling etc), resulting in a first release
* Generate awareness and grow a community!

December was a busy month. Lots of updates to the code base and our working toolchain. 

We would particularly like to thank infra for all the work getting us setup with git. We really appreciate the effort and valuable discussion surrounding it. It is this sort of attention to community that makes us grateful to be members of the Apache community.

* shipped 1.3 with full windows phone support (NOTE: this was not an ASF release; this is next for us)
* BlackBerry Playbook support
* started migration to Cordova name
* git migration complete
* battery events api (http://docs.phonegap.com/en/1.3.0/phonegap_events_events.md.html#Events)
* first version of the project web site up

Graduation concerns:

* Complete the migration to Apache infrastructure
* Make an official Apache release
* Grant committership to new contributors

DeltaSpike will consist of a number of portable CDI extensions that provide useful features for Java application developers. The goal of DeltaSpike is to create a de-facto standard of CDI-Extensions that is developed and maintained by the community.

There are currently no issues requiring IPMC or Board attention.

Since our last report on December 12, 2011, we have accomplished the following:

 - Finished the discussion about coding conventions and added the corresponding checkstyle rules
 - Finished the discussion on the first features
 - Finished infrastructure topics together with the infrastructure team (GIT repository, nightly builds with Jenkins, Sonar setup)
   (Only the JIRA plug-in for GIT is missing because there are issues with using it side by side with the plug-in for SVN)
 - Most initial committers signed their ICLA and got their account
 - Started discussions on the next features
 - Started with the build structure
 - Started with the test-infrastructure
 - Started to migrate core feature contributions from Seam3 and CODI
 - Started to add information to the Wiki to help new folks getting involved
 - Started discussions about tools for our documentation and website
 - Started with the status page (based on http://incubator.apache.org/guides/website.html)

Upcoming major goals:

 - Finish test-infrastructure to allow in-container tests
 - Finish the setup for the documentation and the website
 - Finish the discussions for all features which will be part of the first release

Top 2 or 3 things to resolve before graduation:

1. Build community
2. Create at least one release
3. Create Documentation

(introduced to Apache incubator on Jul 4, 2011)

Kafka provides an extremely high throughput distributed publish/subscribe messaging system. Additionally, it supports relatively long term persistence of messages to support a wide variety of consumers, partitioning of the message stream across servers and consumers, and functionality for loading data into Apache Hadoop for offline, batch processing.

A list of the most important issues to address in the move towards graduation

   1. Invite diverse new active committers

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

We incurred significant overhead during our first release; see http://apache.markmail.org/message/rsxjgrrufc6khlqy?q=list:org%2Eapache%2Eincubator%2Egeneral+from:%22junrao%22 for reference. Firstly, there is no good example to follow for a new podling. Secondly, the licensing rules are complex and the documentation is not enough for a new podling to understand. This gets more complicated since different IPMC members have different views and apply those rules slightly differently. This delays releases and causes overhead to the team. We hope that some of these things can be addressed to make the process easier to other projects.

How has the community developed since the last report?

Activities in the mailing list increased 4x since the last report. Several patches from non-committers have been submitted, reviewed and committed.

How has the project developed since the last report?

We have successfully completed the first release of Kafka after joining the incubator. This releases adds the end-to-end compression feature and mirroring support in Kafka. In addition to this, it also fixes more than 40 issues.

Kato was accepted into the Incubator on 6 November 2008.

Kato is a project to develop the Specification, Reference Implementation, and TCK for JSR 326: the JVM Post-mortem Diagnostics API.

Recent Activity:

* Discussions have been going on with Oracle regarding their participation in JSR 326 and Kato. Initially when the project was started Oracle expressed enthusiasm at participating, however during the acquisition of Sun Oracle was understandably quiet. In more recent times Oracle expressed interest in the project, but this interest hasn't amounted to anything concrete and we've been pushing for Oracle to make a definitive statement regarding it's position on the JSR. 

The following is planned for next reporting period:

* Without any response from Oracle we will assume that Oracle has no interest in the project, and decide what to do with the JSR and Kato unilaterally.
* Decide in what form the podling should continue, if at all.

Before this project can graduate we need to encourage more participation in the project and grow the community.

  Kitty is a command line JMX Client written in Groovy.
  It is a lightweight, production focused, application server performance diagnostic and management utility.

The three most important issues to address in the move towards graduation:
  1) The community around this project is absent, looking at the amount of mails sent to the mailing list in the past months
  2) The lack of a "Product Owner" who can prioritise stories/tasks, leaving the developers without a clue about the functionalities to implement
  3) The code is a port from another language (Jython), and the history of the past project seems lost, so there isn't any reference about how the actual code should work. Also, there is no test (acceptance criteria) in support of that nor for the new features to implement.

Any issues that the Incubator PMC or ASF Board might wish/need to be aware of?
  What seems relevant to me at the moment is the lack of communication between the committers;
  it would be fine if there was a clear statement about who is still interested and who is not in participating in the project, and how to reorganise the now shrunken team, if still there is one.

How has the community developed since the last report?
  Sadly, the community hasn't develop at all; even worse, we faced the loss of some members who were actively involved in the project development/management.

How has the project developed since the last report?
  Jira is not updated, leaving a shade of uncertainty about what has been fixed and what is still in progress since the last report.
  It seems that the last update was done in October, the 4th, with a fix regarding the correct navigation through the server tree in a file-system fashion.

2012-January Tashi Incubator Status Report

Tashi has been incubating since September 2008.

The Tashi project aims to build a software infrastructure for cloud computing 
on massive internet-scale datasets (what we call Big Data). The idea is to 
build a cluster management system that enables the Big Data that are stored in 
a cluster/data center to be accessed, shared, manipulated, and computed on by 
remote users in a convenient, efficient, and safe manner.

Tashi originally encompassed just the tools to manage virtual machines 
using Xen and QEMU, but has been merged with Zoni, which manages the 
physical aspects of a cluster like power control, network settings and 
handing out physical machines.

Development activities have included:-
        * Accounting server has been added to the codebase
        * Primitive scheduler changes
                * bug fixes
                * Add support for user choice of dense packing or not
                * Guard against starting more than one VM with
                  persistent disk
        * Client changes
                * Check syntax of user commands
                * Add support for querying available images
                * Add support for querying image size
                * Add support for copying of images
        * QEMU VMM changes
                * bug fixes
                * Reserve some memory for the host itself
                * Make scratch location configurable
                * Live migrations take a long time, eliminate
                  some timeout values
        * Cluster manager changes
                * bug fixes
                * Reduce network traffic
                * Move accounting functions to new accounting server
        * Branched off new stable version and release candidate
        * Audit compliance with Incubator policies

The project is still working toward building a larger user and development 
community. User groups have been identified in Ireland, Slovenia and Korea,
Malaysia, as well as the United States.

Items to be resolved before graduation:
        * A stable branch exists which could be a release candidate, but
          the codebase is large and test hardware is currently in
          short supply. We are confident that the code in the stablefix
          branch will work if running QEMU emulation, Pickle or sqlite
          data storage, primitive scheduler. Xen, other data stores and
          schedulers have not been tested recently.
        * Develop community diversity (Committers currently at Telefonica,
          Google and CMU)
