Subject Re: [VOTE][RESULT] Accept Apache Ace into the Incubator
Date Thu, 23 Apr 2009 21:15:11 GMT
Time to call the vote on accepting Apache Ace for incubation.

* +1 votes from (* indicates binding votes) Carsten Ziegeler*, Niclas
Hedhman*, Richard S. Hall, Niall Pemberton*, Robert Burrell Donkin*,
Bertrand Delacretaz*, Felix Meschberger, Francesco Furfari, and Karl
Pauls.

* No other votes.

The vote is successful. Thanks to everyone involved. We will get the
ball rolling asap.

>>
>>
>>Proposal
>>
>>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. It is built using OSGi and
>>can be deployed in different topologies. The target systems are
>>usually also OSGi based, but don't have to be.
>>
>>
>>Background
>>
>>When assembling software out of reusable components, the task of
>>deploying software onto an ever increasing number of targets is not
>>trivial to solve. This becomes even harder when these targets require
>>different components based on who's using them.
>>
>>A key technology in the Java space for developing component based
>>applications is OSGi. The OSGi speciï¬ cation, which has been around
>>since 1999 and by now has matured into the de facto module system for
>>Java, allows you to write components that can interact through
>>services and that allows components to be updated individually,
>>without disturbing the rest of the components.
>>
>>Although the OSGi speciï¬ cation describes how software distribution
>>should be done, it does not actually prescribe any protocols or
>>implementations. Apache Ace implements a software distribution system
>>based on, but not limited to OSGi. It is setup so it can deal with
>>different target types, using different protocols. Also, it can handle
>>an extensible number of artifact types (bundles, configurations,
>>resources, ...).
>>
>>
>>Rationale
>>
>>When you start using OSGi to build reusable components, the task of
>>managing those components and their use in various applications
>>becomes non-trivial. Apache Ace allows you to group those components
>>and assign them to a managed set of targets. This allows you to
>>distribute updates and new components easily, while keeping a full
>>history of what was installed where during what period. It also helps
>>you setup an automated development, QA/testing, staging and production
>>environment.
>>
>>
>>Initial Goals
>>
>>The initial goals for Apache Ace are:
>>
>>* Donate the existing codebase and import it.
>>* Setup the incubation infrastructure (svn repository, build system,
>>website) so we can run continuous builds with automated tests and
>>publish all available documentation.
>>* Get people involved in advancing the code base in different
>>directions, integrating it with other projects at Apache.
>>* Prepare for an initial release that demonstrates the systems core
>>capabilities.
>>* Present the project to the community at ApacheCon 2009 US.
>>
>>
>>Current Status
>>
>>The current codebase is developed and tested in various
>>configurations. It was developed at luminis over the last couple of
>>years using Scrum, so we have internally demonstrated we can release
>>often and produce working code using a transparent process.
>>Documentation for the project is now available on an internal wiki,
>>which can be donated and converted to the Apache Ace website. We did
>>not yet use mailing lists as the primary colaborative process, as the
>>whole team met face to face on a daily basis.
>>
>>
>>Meritocracy
>>
>>Some of the core developers are already committers and PMC members at
>>Apache, so they understand what it means to have a process based on
>>meritocracy.
>>
>>
>>Community
>>
>>In the past, luminis has been talking to various interested users and
>>developers about Apache Ace, and we believe there is an interest in
>>this project. Feedback at ApacheCon EU 2009 and afterwards on the
>>Apache Felix mailing list confirmed that. The problem that is being
>>solved is one that many software developers run into, so it should
>>appeal to them. Our list of initial committers already includes people
>>from different backgrounds.
>>
>>
>>Core Developers
>>
>>The core development team is a mix of people that work for luminis and
>>have been involved in the project up til now and new committers, some
>>of which have previous experience at Apache.
>>
>>
>>Alignment
>>
>>The initial codebase makes use of Apache Felix as its core framework.
>>It also uses various other components of that project. As a project
>>that builds on components we are constantly looking out for existing
>>components that can accelerate our implementation and we want to
>>actively work with other projects to make that happen. For building
>>and testing we use Apache Ant and have developed a couple of
>>extensions that help managing OSGi projects. Finally, at least
>>informally a couple of projects at Apache have already expressed
>>interest in a system that can help them do software provisioning.
>>
>>
>>Known Risks
>>
>>Apache Ace uses Felix as its default OSGi implementation and some of
>>its developers are also part of the Felix community. We are open to
>>collaborate with other Apache projects, looking at candidates such as
>>Commons, Sling, JackRabbit that could help us in certain parts of our
>>infrastructure.
>>
>>An important reason for open sourcing this project at Apache is the
>>strong community, as well as the Apache license. This will attract
>>more users and developers so the project can be moved forward into new
>>directions that we would otherwise not have been possible. Judging
>>from the initial interest from some of the other projects at Apache,
>>we certainly see ways in which to collaborate and advance the project,
>>possibly in ways we would never have thought of. However, we have been
>>able to support and develop this product outside of Apache quite well,
>>so in no way are we trying to just dump the code there or merely
>>trying to generate publicity.
>>
>>
>>Initial Source
>>
>>Apache Ace has been in development within luminis since 2005.
>>
>>
>>Source and Intellectual Property Submission Plan
>>
>>The current codebase is owned by luminis, and will be donated together
>>with its documentation. We will get the paperwork out of the way as
>>soon as possible. There should already be a CCLA on file for luminis
>>and the people that are already involved with Apache obviously have
>>ICLAs on file.

>>libraries, their sources and licenses are listed here:
