New project proposal to bring a modular framework and OSGi-like capabilities to Flex development.

ElementRiver have submitted the Potomac
Framework for Flex
as a new Eclipse project, where it will
exist under the banner of ‘The Flex Modularity Project.’

The Potomac framework was originally inspired by the Eclipse RCP
and OSGi, and sought to solve the problems of modular

The project aims to bring OSGi-like capabilities to Flex,
implement a modular framework for enterprise Flex development,
provide an extensibility mechanism, and provides tooling that
allows Adobe’s Flash Builder 4 to support Potomac bundle
development. The project will provide asynchronous and
‘bundle-aware’ dependency injection, and also plans to enable
Potomac Flex component hosting within e4 applications, at some
point in the future. Potomac will consist of Flex and Actionscript
code, and will not have any server-side requirements or

Potomac will work by providing bundles that contain the classes
and code, but also the metadata for understanding module
dependencies, extensions and extension points.

ElementRiver will contribute the initial code from the existing
, and Adobe has agreed to provide each Potomac
committer with a free license for Flash Builder 4.

The release of Potomac version 1.0 is currently scheduled for
September, 2010.
