Free persistence framework software for linux

Echo is a framework for developing object-oriented, event-driven Web applications.
Echo removes the developer from having to think in terms of "page-based" applications and enables him/her to develop applications using the conventional object-oriented and event-driven paradigm for user interface development.
Knowledge of HTML, HTTP, and JavaScript is not required. Echo is open-source software distributed under the terms of the Mozilla Public License or the GNU LGPL License.
Enhancements:
- Version 1.1.4 adds support for specifying the order of tab-based navigation of components. The release also fixes bugs reported in previous versions, including the issues discovered with setting component focus.

XOscript is a transparent communication bridge between objects running in an application server and the browser. JavaScript programmers have access to the methods supported by server side objects. No additional coding techniques are required to call the method of a server side object. Java programmers are free to build an application using any coding style they choose.

The xoscript framework fully supports Java security. During the invocation of any method the Java programmer may have access to the session metadata as well as cookies, params and attributes passed at method call time. No additional argument signatures are required. The framework supports any method return type including object, primitive or client supported Map and Collection interfaces and may pass an array of the aforementioned.

The JavaScript programmer can take advantage of client side support for all of the Map and Collection interfaces used by Java programmers. Supports for 33 of the most useful classes found in the java.util package have been written in JavaScript.

The goal of this project is to let you code the way you want. Providing a simple framework that stays out of the way yet opens the communication gap between the browser and server. Allowing applications to be written without regard to what the framework can or can not handle. A great deal of thought has gone into the most natural way to achieve this end. Using the default implementation of the framework allows for 90 percent of the code just the way it is written today. Under the covers xoscript is divided into 3 services, invocation, persistence and logging. Each of these services can be implemented through a factory class that understands how to create and use your implementation of the service.

Future goals include bringing a server to client event model into the framework enabling the browser and server to interact as if they were one program and building in support for client side custom tags that can be driven by server side logic. Hope you enjoy XOscript.

Business Oriented Framework (BOF) is a Perl application server. It uses SOAP, optionally secured with SSL, to communicate with the client.
The client can use SOAP::Lite or the client module included in BOF, making it easy to connect to the server. User, grou
Enhancements:
- Added support for Schedules and tasks

Molins is a framework for the development of applications with PHP 5. Its more important features are database persistence, logging, unit testing, dynamic content generation (PDF, Flash, graphics, XML), security roles, GTK+ wrapper classes, and a complete Web MVC model (using XSLT). It is fully object-oriented, with class packaging similar to Java.
Enhancements:
- This version is focused only on bugfixes.
- The most important bugfix is related to the exception handler.

WebWork MVC Framework is a Java pull HMVC Web application framework, designed for creating dynamic websites using minimal effort and maximum flexibility.
It supports multiple views, allowing you to switch between different view technologies, including HTML, Swing, PDF, XSLT, and Velocity, without changing the logic producing the data.
It includes a powerful expression language for navigating its object stack, as well as a small but complete tag library. WebWork MVC Framework supports internationalization, error handling, chaining actions, validation, command driven actions, redirection and type conversions.
Enhancements:
- Full support for Java 5 Annotations and Generics.
- Rich AJAX support using DWR and Dojo.
- A new QuickStart tool makes development easier.
- Client side validation using AJAX or plain JavaScript.
- Built in support for Continuations.
- A rich UI template framework.
- Native support for Spring and Pico IOC containers.
- More intelligent error reporting.
- Developer Mode makes building Web applications easier with improved error reporting.
- A simplified tag syntax.
- An advanced data binding framework that works with any object, including domain objects.

Biome is a simulation library aimed at individual-based or agent-based simulations (like Swarm or EcoSim). Biomes features include a fast rng, an event-based scheduling system, Qt classes for graphs and histograms, an analysis framework, a basic persistence framework and many more.
Enhancements:
- An easy-to-use command line parser, a unified parameter class able to read from files or the command line, and a simple SDL canvas class were added.
- Many bugs and compatibility problems were removed.
- Many internal changes were made.

machine learning framework for Mathematica is a collection of powerful machine learning algorithms integrated into a framework for the main purpose of data analysis.
Fuzzy logic is one of its key techniques. The framework allows for combining different machine learning algorithms to solve one single problem. This combination of distinct algorithms may give the user unforeseen insights into its data.
The algorithms are highly parameterizable. Given this parameterizability combined with the efficient core engine of the machine learning framework for Mathematica, the user is able to analyze their data interactively, with short cycles of changing parameter settings and examining the results.
The machine learning framework for Mathematica covers a wide range of machine learning algorithms which can be integrated to work together and therefore yield new results.
Enhancements:
- runs native on Intel-Macs
- runs in 64-bit mode on G5-Macs
- fuzzy decision trees
- fuzzy rule learning
- fuzzy regression trees
- cluster descriptions
- optimization of fuzzy controllers
- self-organizing maps
- automated model testing
- advanced data visualization.
