SMS Framework is an Objective C framework for decoding SMS messages in PDU format to objects.
It is easily usable in Cocoa and GNUstep environments, and it reduces developer responsibility for decoding messages to extracting the raw messages from the phone.
The XCode project file contains three targets: one system wide framework, one framework to include in applications, and a small application for testing the framework.
Enhancements:
- Fixes two small bugs in decoding that seem to affect international users.
- The bugs became apparent after OS X 10.4.5 appeared.

SA Web Framework project is a complete PHP application framework, based on the Front Controller Pattern.
SA stands for SkyApp? and is the framework which we developed and which we are using here at Skyweb.
SA is open source and released under LGPL license which means you can use it for free.
SA relies heavily on PEAR which gives us access to some nice features like mime mail handling, independent database abstraction layer, destructors, database session storing and many more.
SA was developed and tested using PHP 4.4.0.
Enhancements:
- The whole application stack has been rewritten in order to take advantage of the PHP5 object model.
- Some new classes and interfaces were introduced and the existing ones were completely rewritten.
- A new Page handling concept was implemented.
- The default page class now extends Smarty.

Salto Framework is a framework based on Ajax, Struts and J2EE technologies. Salto Framework provides graphical components such as datatables, treeviews and listboxes, and allows you to refresh only some parts on the screen. Thanks to the framework you dont have to write any javascript or to know anything about Ajax mechanism.

Joshs Website Framework is a CMS framework for PHP Web developers. Joshs Website Framework consists of various subcomponents you can extract and use individually. SaxInterface provides an OO wrapper for SAX XML parsing.

The Auth Engine provides both level-based permissions (e.g., must be level 100 to access this page) and name-based permissions (e.g., must be in "editor" group to access this page).

Utilities include Mutex and SharedData classes (for interprocess communication), site-wide custom error handling, and the ability to take a site offline for maintenance.

ROMA wants to change the way to do Java Applications. Its a Meta-Framework designed to build cross frameworks applications in very short time.
ROMA wants to glue the best of Java tools and frameworks together. ROMA doesnt want to reinvent the wheel or another brand new Web Framework, but just use the existent products with very low effort for the developer.
Main features:
- Roma its totally based on POJO (Plain Old Java Objects)
- True Object Oriented vision in all aspects: from the model to the view and to the repository/database
- Encourage the use of the Domain Driven Model (DDD) approach: lets think to the Domain: the other things are secondary Aspects
- It works with Conventions? ala Ruby On Rails: much less code to write and maintain and more uniformity in projects
- Applications are fully portable across frameworks since the application is developed using POJOs. For example you can switch between JDO and EJB3 PersistenceAspect without changing code unless you use directly the aspect implementation (see below)
- Allow to makes things dirty: you can use directly the target framework taking the full advantage of the implementation power
- You can use the already developed Modules (CRUD, User&Profiles, etc.) and extend their if you need
- The skill requested to build application can be lower than required for modern Java Web Applications: minor cost of development
- Roma is based on Spring Framework as IoC container, but you can use another one if you want.

Xholon runtime framework executes applications that are event-driven or that have highly dynamic structure or behavior. Specify your models using XML and Java, or using third-party UML2 tools and MDA transformations.
To get started, read or actively work through the basic HelloWorld tutorial. Its a very simple application, but it demonstrates many of the main concepts.
For more detail on the concepts behind Xholon, you might want to read one of the papers thats been published. These describe how to model cells and other complex biological entities using tools designed for developing real-time and embedded systems.
This earlier work used Rational Rose RealTime and C++, rather than the current Java. Xholon is intended to be a runtime framework that can execute the same types of systems described in those papers, plus many more traditional non-biological event-driven systems.
The goal of the Cellontro sister project is to develop complex biological simulations using the Xholon framework. Most of the features described in the published papers have been re-implemented as Cellontro applications using Xholon.
Also have a look at the sample applications that are included with the Xholon software. These give an idea of the range of applications that can be supported by the Xholon runtime framework.
These have been employed as use cases to determine what functionality is most important in Xholon. The digital watch simulation is a good example of a Xholon application with a hierarchical state machine, developed using a UML modeling tool.
A Xholon is essentially a holon. A holon is an entity that lives within a hierarchical structure, and is both a whole and a part at the same time.
In mainstream computer science terms, a Xholon is a node in a tree. The node has a single parent, possibly one or more children, and possibly one or more siblings. A Xholon may also be an active agent able to interact in real-time with other Xholons in the tree.
In UML2 terminology, a Xholon is a structured classifier that may exist as a part within other structured classifiers, and that may in turn contain other structured classifiers as parts of itself. The result is a hierarchical containment structure, nested to an arbitrary number of levels.
As a part, a Xholon plays a specific role within another structured classifier. Xholons are UML classes that are subsequently refined using UML2 composite structure diagrams. Structured classifiers interact with each other through ports, by passing messages or by making function calls.
Using the more philosophical terminology used to describe holons, a Xholon is something that is simultaneously both a whole and a part. Since everything in the universe is a holon, then everything running within a computer application should be a Xholon. The term holon was invented by Arthur Koestler in 1967.
The Xholon Project is inspired by biological concepts. A major incentive behind the project is to build a run-time environment that is equally adapted to running simulations of biological systems, and to running more traditional real-time, embedded and other event-driven reactive systems.
Xholon applications may contain structures that are highly mutable. A Xholon is an active agent that can modify the tree structure in which it lives. It can navigate the tree to interact with any other node, it can add, delete or modify other nodes, it can exchange messages with other nodes, and it can move itself to another position within the tree.
The Xholon Project incorporates many concepts of the Real-time Object-Oriented Modeling (ROOM) methodology, much of which has been incorporated into UML2. At the same time, Xholon removes some of the limitations of ROOM to allow for greater flexibility, mutability and mobility of active objects.
The Xholon run-time can serve as a target for a Model Driven Architecture (MDA) transformation pipeline. MDA stresses the importance of models, and the ability to transform those models, through a series of steps, into an executing target system.
You can create your model using a UML tool such as Gentlewares Poseidon or NoMagics MagicDraw, save the model as an XMI file, transform it using XSLT (or by some other MDA means) into a Xholon model and application, and then execute the model.
Enhancements:
- UML state machine simulation capabilities have been extended, including animation, and fork, join, junction.
- Additional Agent-Based Modeling functionality is available.
- The NetLogo-like syntax has been enhanced.
- The architecture is more flexible and is ready to more fully support integration of multiple domains.
- Histograms and probability distributions are now available. Line charts update in real-time.
- Numerous other modeling, simulation, transformation, and execution features have been added.

Aranea framework 1.2.2 is professionally designed as an Open Source Java Hierarchical Model-View-Controller Web Framework that provides a common simple approach to building the web application components, reusing custom or general GUI logic and extending the framework.
