It is great to see more companies come along with open source contributions a la http://opensource.adobe.com.
The main seed release revolves around Adam and Eve:
Adam is a modeling engine and declarative language for describing constraints and relationships on a collection of value, typically the parameters to an application command. When bound to a human interface (HI) Adam provides the logic that controls the HI behavior. Adam is similar in concept to a spreadsheet or a forms manager. Values are set and dependent values are recalculated. Adam provides facilities to resolve interrelated dependencies and to track those dependencies, beyond what a spreadsheet provides.
Eve consists of a declarative language and layout engine for constructing an HI. The layout engine in Eve takes into account a rich description of UI elements to achieve a high quality layout - rivaling what can be achieved with manual placement. A single HI description in Eve suffices for multiple OS platforms and languages. This document describes Eve2, the latest version of Eve. Eve2 was developed to work with Adam and to incorporate many improvements that have been requested since Eve1 was written.
It is important to note that Adam and Eve do not constitute a traditional application framework. They are component libraries which can be incorporated into a number of environments. They can be used together, or independently, but must be combined with other facilities to construct an application. Nearly all of the components which comprise Adam and Eve can also be used independently and are documented as part of ASL.
ASL is being developed in C++, and relies heavily on the Boost libraries http://www.boost.org which are required for building ASL.
It seems like companies are coming out with two forms of community news:
New Open Source Contribution!
New Web Services APIs To Our Services
There are some interesting differences between the two :)
