For the last two years, AOL has been promoting its OpenAIM initiative as a vehicle to enable developers to build their own AIM (AOL Instant Messenger)-based clients. But there were issues with documentation that got in the way of some projects.
With the release of Open AIM 2.0 Wednesday, AOL is aiming AIM at open source developers with more ease-of-use tools.
Among the major changes in Open AIM 2.0 is the fact that AOL is now providing open documentation on its core OSCAR protocol (Open System for CommunicAtion in Realtime), which powers AIM. Previously, open source instant messaging client implementations of OSCAR had to reverse-engineer the protocol instead of simply using a documented protocol.
There is, however, a catch.
Although Open AIM 2.0 provides open access to the OSCAR protocols, developers need to do something for AOL in return. AOL requires that developers choose two options from a list of five items that must be added to an Open AIM-based client.
