Ace

Apache ACE is a software distribution framework that allows you to centrally manage and distribute software components, configuration data and other artifacts to target systems. ACE started incubation on April 24th 2009.

There are currently no issues requiring board or Incubator PMC attention.

Community:

Angelo gave a talk about massive device deployment and Karl and Marcel did a tutorial about ACE in the Cloud at EclipseCon / OSGi DevCon.
We're gathering EclipseCon / OSGi DevCon feedback to populate the roadmap and raise the corresponding Jira issues.

Software:

A lot of work has been done on the build to fully support Maven 3.
We started to work on the documentation also.
Use of Apache Karaf as default runtime is in progress.
Cloud extensions based on jclouds have been added, including a new launcher.

Licensing and other issues:

None at the moment.

Things to resolve prior to graduation:

We created a SVN maven repo waiting for some Felix dependencies release.
Make a release.
Grow the community some more.

Celix

Celix is an implementation of the OSGi Specification in C.

Celix entered incubation on November 2, 2010.

During the EclipseCon a talk was given over Celix, also spoke with several OSGi people who are interested in the progress, especially related to Universal OSGi (which details specification and requirements for OSGi in other languages).
During the last few weeks work has been done to get rid of memory leaks and null pointers.
Currently we are looking at the requirements/details for bundle deployment and updating, possibly in combination with Apache Ace.

Most important issues are:

- Define a status overview of what is and isn't working.
- Move all "sub" project to the new structure.
- Use APR for all file handling, threading etc.
- Generate awareness and grow a community

EasyAnt

EasyAnt is a tool built on top of Ant and Ivy providing a standard approach to building java projects without locking the users in.

Incubating since January 31st 2011

issues/agenda:
- 1 ICLA missing. The person does not answer since Feb 4th 2011, when he indicated he was working on getting the ICLA. The svn logs have been gathered and shared between the PPMC members in preparation for a possible cleanup of the svn tree of that person's contribution.

activity since last report:
- the web site http://incubator.apache.org/easyant/ is published via svnpubsub
- while reviewing the licences of the software included in the svn tree of Easyant, some dependency on external LGPL library was found. There are somehow optional to EasyAnt core, but not for the "plugin" dedicated to the integration of that third library. A consensus was found by the developer community to not release such software under the ASF.

Empire-db

Apache Empire-db is a relational database abstraction layer that allows developers to take a more SQL-centric approach in application development than traditional ORM frameworks. Its focus is to allow highly efficient database operations in combination with a maximum of compile-time-safety and DBMS independence. Empire-db has entered Incubation in August 2008.

Activity since last report:
- We have successfully completed and published our 2.1.0 release with few but major improvements.
- We have increased your community by taking on a new long-time contributor as a new committer.

Important issues to address for graduation:
We still need more contributors and more attention in the Java community. Recently we experience increased traffic on the user lists and there are plenty of plans on the development side. The challenge will be to keep users interested and let them participate in the development process.

Jena

Jena was accepted into the Apache Incubator November 2010
(http://mail-archives.apache.org/mod_mbox/incubator-general/201011.mbox/%3C4CEC31E4.9080401@apache.org%3E). It is an existing project migrating to ASF. It has a large
codebase that provides a semantic web framework in Java that implements
the key W3C recommendations for the core semantic web technologies of
RDF and SPARQL.

Three most important issues to address for graduation:

* Create a code base in Apache with legal clearance.
* Establish the Apache-based community for developers, contributors and
users
* Create and communicate open project processes aligned to Apache

Issues for the Incubator PMC or ASF Board:

None.

Community development:

We have started to advertise the existence of Apache-hosted mailing lists. Traffic on these lists continues to grow.

A new work area on enhancing the native storage system with trsnaction support is being conducted in public on Apache cwiki and mailing lists.

Project development:

We are still awaiting the software grant from HP. As this is the majority of the codebase, we are waiting for this before migrating any code into Apache SVN. We understand that HP has progressed this and has decided on the details for signing.

Olio

2011-April Olio Incubator status report

Olio is a web 2.0 toolkit to help developers evaluate the suitability, 
functionality and performance of various web technologies by implementing 
a reasonably complex application in several different technologies.

Things have been fairly quiet on both the user and developer list this quarter.

Graduation From Incubation:

The user base is not showing growth. Since this is a test application/workload, 
it is being used as such for short-term projects.

Rave

Apache Rave is A new WEb And SOcial Mashup Engine. It will provide an out-of-the-box as well as an extendible lightweight Java platform to host,
serve and aggregate (Open)Social Gadgets and services through a highly customizable and Web 2.0 friendly front-end.

Rave just entered incubation on 2011-03-01, this is our first board report.

Mailing lists, SVN and user accounts have been created, Issue tracking (JIRA) and  continuous integration (Jenkins) have been setup.

All the three initial code donations have been provided and imported in SVN.

Website creation and management is underway, using cms.apache.org, but currently still in staging only.
Getting the website ready for publishing is high priority.

Branding requirements will be taken care of together with the website.
Discussion on creating and selecting a Rave logo is underway on the developer mailing list.

The committers voted on and selected Maven as build engine for Rave.
A basic Maven project is committed. Discussion about the new code base and features to implement has started.
The project code base will be created from scratch, not be based on or directly incorporate the initial code donations.
Under discussion on the developer list also is choice of development methodology and style.

Next steps:
 * Get the Rave website ready for publishing, select a Rave logo and fulfill the branding requirements.
 * Reach out to the community and build up awareness of Apache Rave.
 * Proceed with building up the new code base and work towards a first (incubator) release.

Tashi

2011-April 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 has previously encompassed just the tools to manage virtual
machines using Xen and KVM, but is gaining the facility to hand out
physical machines as well.

Development activities have included:-
        * Importing bug fixes from CMU deployment
        * Don't display exceptions if failure is expected
        * Validate fields and clean invalid instance entries
        * Eliminating inconsistent state between node and cluster manager
        * Allow hosts to be soft powered off via ACPI
        * Refactor primitive scheduler to be less convoluted (ongoing)
        * Define a stable branch for tested code
        * Example support for dynamic scratch space disks
        * Enforce designated copy-on-write data filesystem for Qemu

The project is still working toward building a larger user and development
community. User groups have been identified in Ireland, Slovenia and Korea,
as well as at Georgia Tech. CMU usage is growing as other groups hear about
the availability of the resource. Intel has restructured its research
division and folded some operations into adjoining academic sites.

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.
        * Scratch space integration would be desirable, accounting
          integration is probably a necessity
        * Develop community diversity (Committers currently at Telefonica,
          Google and CMU)
