Welcome to the official home of ARP, the Open Source Pattern-Based Rich Internet Application (RIA) Framework for the Flash Platform.

ARP currently supports Macromedia® Flash® and Flex™-based RIA Development in ActionScript 2 and ActionScript 3.

NEW: Arp now supports ActionScript 3. See Aral's blog post for more information.

ARP was initially authored by Aral Balkan and is currently maintained and evolves under the guidance of the ARP Advisory Committee with input from the ARP Community.

Arp has a mailing list where you can discuss the framework and ask questions (make sure you search the archives first before asking a question as it might already have been asked and answered before.)

Sign up for it here: ARP Mailing List

ARP is designed to be simple to use and lightweight. To learn more about ARP, read through the easy-to-follow yet comprehensive Developer's Manual. You can also share suggestions, contribute to ARP’s future development and get support from both the development team and our ever-growing community of some of the best Flash and Flex developers in the world by subscribing to the ARP Mailing List.

You can download the latest development version(s) of ARP directly from the ARP Subversion Repository on CVSDude:

• http://svn1.cvsdude.com/osflash/arp/
• See also: Advisory Branch with experimental changes, additions and extensions by the ARP Advisory Committee. ARP Advisory Committee members also have their own labs for their own experiments.

The release version (installer) of ARP is currently outdated Version 2.02. This version still uses the old package names (com.ariaware) as opposed to the new org.osflash.arp package structure. Our next release (2.03) will essentially be identical to 2.02 but contain the new package structure.

The current release version of ARP is 2.0.2. Since its release, the ARP user and developer communities have created home-grown extensions to ARP. One of the reasons we formed the Advisory Committee was to gather these together, along with other experimental additions and utilities with the aim of making them part of ARP. In the meanwhile, the ARP Extensions page will serve as a resource with links to community-contributed extensions to ARP.
