Subject [Incubator Wiki] Update of "FlexProposal" by AlexHarui
Date Mon, 19 Dec 2011 20:02:28 GMT
Dear Wiki user,

You have subscribed to a wiki page or wiki category on "Incubator Wiki" for change notification.

The "FlexProposal" page has been changed by AlexHarui:

New page:
= Apache Flex Proposal =

== Abstract ==

Apache Flex is an application framework for easily building Flash-based applications for mobile
devices, the browser and desktop. 

== Proposal ==

Apache Flex allows developers to target a variety of platforms, initially Apple iOS, Google
Android, RIM !BlackBerry, Microsoft Windows, and Mac OS X with a single codebase. Flex provides
a compiler, skinnable user-interface components and managers to handle styling, skinning,
layout, localization, animation, module-loading and user interaction management. 

== Background ==

Apache Flex is the software evolution of the popular Adobe Flex SDK project. 
Adobe Flex SDK evolved from the need to provide developers with an easy programming model
for creating rich Internet applications that can run in the browser, on the desktop or on
mobile devices. 

Adobe Flex SDK has always focused on a single goal: to provide application developers with
all of the constructs needed to boost their productivity while building large-scale, visually
expressive applications. This meant that Flex provided all the traditional UI components in
a way that designers and developers could interact with them along with a dynamic scripting
language, !ActionScript, and a declarative markup language, MXML. 

Adobe will donate the Flex trademark to the Apache Software Foundation as part of the incubation
process. The source code, documentation and related assets will all be contributed to the
Apache Foundation as Flex.

== Rationale ==

Content developers need to target multiple screens and the cost of creating applications native
to every target platform is high. Additionally, the dominant window to the web is quickly
becoming devices, mostly phones, and delivering consistent experiences is key. The Apache
Flex project exists to bring the focus back to a consistent development model, one where a
single application can run the exact same way across the web, desktop and mobile devices.

== Initial Goals ==

 * Donate all Adobe Flex SDK source code and documentation to the Apache Software Foundation.

 * Setup and standardize the open governance of the Apache Flex project.
 * Rename all assets from Adobe Flex SDK to Apache Flex in project source code, docs, tests
and related infrastructure.

== Current Status ==

Flex is a mature software project. 1.0 was shipped in March of 2004 with 7 major releases
having shipped since. The most recent release was the 4.6 version which shipped on November
29th, 2011. 

== Meritocracy ==

The Adobe Flex source code is available to the community on the Adobe opensource site:
 Currently, while the community has been invited to contribute patches to the codebase, only
Adobe employees decided on which patches to commit.  There were no external committers and
this caused frustration in the community.

Going forward, both Adobe and our community are eager to become one single merit-based community
working together.  To that end, Adobe will only have minority representation on the initial
committers list.  Adobe is working to educate our community with meetings and blog posts on
how the Apache model makes this possible for them.

We have made it clear to our community that going forward, the community, rather than Adobe,
will determine the future of Flex.  

== Community ==

The community surrounding Flex is vast, diverse, distributed globally, and with all levels
of proficiency in software development. The common thread of application development binds
all Flex developers together. 

It is estimated that there is between 350,000 and 500,000 Flex developers worldwide. Precise
numbers are impossible for us to know due to the open nature of Flex. A blog post calling
for initial committers received over 60 responses in two days.   The !FlexCoders mailing list,
a general-purpose mailing list for anyone working with Flex, has over 9000 members.  A quick
look on the Adobe Forums or Twitter’s #!AdobeFlex hashtag usually shows activity within
minutes. The community is engaged and active daily and incredibly excited by Adobe’s move
to contribute Adobe Flex SDK to Apache. The community is responsive, inclusive and honestly
emphatic when it comes to bettering Flex for application development. 

== Alignment ==

The only way the Apache Flex project can work is if it is an open, transparent and collaborative
effort. The project has now grown in mind-share and community enough that we believe it is
time we work with a foundation to see the code mature in a fashion consistent with our values.

== Known Risks ==

Moving from a corporate-led project to the Apache model of collaboration is a challenge, and
Adobe is committed to help making the transition as smooth as possible, by delegating employees
to work on the new project. We would like to see more free collaboration from the community
but with the same principles that has kept Flex with the high-quality design and ease-of-use
it has maintained under Adobe’s governing hand. 

== Documentation ==

We will, over time, be moving all of the documentation, including localized versions, from
Adobe ( to the Apache Software Foundation.

== Initial Source ==

All code related to the Apache Flex project can be found on SVN here:

== Source and IP Submission Plan ==

 * All canonical source will be moved to Apache infrastructure under the name Flex.
 * Documentation and specifications will be moved completely over to the Apache systems.
 * The existing Flash Builder trademark will be used as a commercial entity.
 * Existing Flex-related conferences, podcasts and websites should be allowed to continue
using “Flex” as part of their name - Apache Flex will have to create guidelines for that.

== External Dependencies ==

Some parts of Flex development rely on third-party libraries.  The complete list is still
being determined but some are:
 * Adobe AIR SDK
 * Adobe Flash Player SDK
 * Adobe Text Layout Framework (TLF)
 * Adobe Open Source Media Framework (OSMF)
 * Adobe Font Engine (AFE)

Licensing of these dependencies will have to be checked, and possibly adapted, to allow their
use in Apache Flex.
