SME Web Application Framework provides a Web application framework for small and medium-sized organizations.

SMEWebApp is a framework for constructing Web applications for SMEs (small and medium-sized enterprises, companies, institutions, and organizations). It is built on phpWebApp, and it is higher-level and more specific than phpWebApp.

It has some components that can be reused in any application (perhaps with small modifications), like hierarchical menus, user authentication, and user administration.

The aim of the project is to make Web application construction for SMEs easier than using VB.

Calyxo Web Application Framework encourages in MVC model 2 based web application development.

It offers support for true modular applications, i18n, a flexible view manager, a powerful validation engine, and more! Calyxo is entirely written in Java and builds on the latest Servlet and JSP technologies.

The Calyxo project divides into several components

Calyxo Base - this component collects some of the basic, reusable classes used throughout all the other components. It introduces basic concepts like modules, i18n, accessors and so on...

Calyxo Control - this component implements the Calyxo controller. Calyxo uses an approach similar to Struts here, so Struts users should feel familiar with Calyxo from the start. Calyxo Control may be considered as the "main part" of the Calyxo platform.

Calyxo Forms - this component allows the definition of forms, along with all their validation steps and lets you map inputs to properties of a data object. Complex validations, dependencies between inputs and mapping an input to a set of properties are supported. The Calyxo Forms JSP tag library provides replacements for HTML elements related to forms.

Calyxo Panels - this component allows the definition of pages in a container/component manner. Pages are dynamically composed from a tree of page fragments. Panel definitions may be nested to arbitrary depth and may use inheritance.

Calyxo Struts - this component focuses on integrating Calyxo parts into the very popular Apache Struts framework. The Calyxo Panels and Calyxo Forms components may be used with Struts to replace Struts Tiles and the Struts Validator.

Keystone is a cross-platform, object oriented application framework which allows applications to be written to build on the target platforms of GNU/Linux and Win32 without modification of their source.
Keystone Application Framework implements several modern Web standards, including SVG graphics and the XUL user interface description language.
Enhancements:
- A significant development in this release is the optional use of the GDI+ (Win32) and CairoGraphics (Linux) rendering backends to render SVG content.
- In addition, support for SVG paths has been much improved with the ability to render bezier and elliptical segments.

php.MVC implements the Model-View-Controller design pattern, and encourages application design based on the Model 2 paradigm. This design model allows the Web page or other contents (View) to be mostly separated from the internal application code (Controller/Model), making it easier for designers and programmers to focus on their respective areas of expertise.
The framework provides a single entry point Controller. The Controller is responsible for allocating HTTP requests to the appropriate Action handler (Model) based on configuration mappings.
The Model contains the business logic for the application. The Controller then forwards the request to the appropriate View component, which is usually implemented using a combination of HTML with PHP tags in the form of templates. The resulting contents are returned to the client browser, or via another protocol such as SMTP.
php.MVC is a PHP port of Jakarta Struts. It currently supports many features of Struts, including declarative application configuration via the XML digester. For example, mappings from the various Action business logic components to appropriate results pages can be specified declaratively in the XML configuration file.
Main features:
- Free OpenSource software: This gives users full control of the software, and the able to modify the source code to suit specific needs.
- Security: php.MVC applications have only one entry point (per application). This makes it easy to protect sensitive application code and data.
- Flexible Installation: Individual php.MVC applications can be installed outside of the main php.MVC library directory tree.
- Multi-applications: There is no limit to the number of applications per php.MVC installation.
- Object Oriented design (OOD). The php.MVC framework is based on OOD principles, making it more extendable and maintainable.
- Database integration: The php.MVC framework ships with the Pear::DB Database Abstraction Layer, and a driver for the MySQL relational database manager (RDBM) is provided.
- Action Chaining: php.MVC allows for passing control to other Actions. This makes it easy to process a sequence of Actions (business logic classes) and static resources (pages).
- XML configuration: php.MVC uses declarative application configurations using Extensible Markup Language (XML) files. Each application has its own XML configuration file.
- MVC Model 2 design: php.MVC implements the Model-View-Controller (MVC) Model 2 design pattern. The Model 2 paradigm allows the separation of the application presentation from the business logic, making it easier for designers and programmers to focus on their respective areas of expertise.
- Form button mapping: php.MVC implements the LookupDispatchAction class to enable HTML form buttons to be mapped to particular business logic methods. For example, a form submit button called "Add to Cart" could be mapped to an Action class method called MyCartAction->addToCart(...).
- Message Resources: php.MVC provides a PropertyMessageResources class that handles messages in text string properties files with parametric replacement. This can provide Locale-sensitive messages for internationalized applications.
- The php.MVC framework is based on Jakarta Struts application framework design. Struts has proven to be reliable, extendable and well supported.
Enhancements:
- This development release adds bugfixes and enhancements to the framework, a compressed performance version for use in more demanding hosting environments, and an example application to demonstrate the use of both versions.

PIC USB Framework is a USB application framework dedicated to Linux (on the host side) and to the PIC 18F4550 family of microcontrollers (on the device side).
PUF includes: a bootloader that can flash the PIC application through the USB, a PIC demo and its corresponding application on the host side, and docker, the host-side flash programming utility.
The PUF also contains gputils and sdcc as cross-building tools, and odyssey 0.4vasco as a parallel port PIC programmer.
Enhancements:
- sdcc optimization flags are now switched on by default.
- A component library (including a console mechanism and a small real time scheduler) has been added to help building user applications.
- Tools have been upgraded to automake 1.9.6, autoconf 2.59d, sdcc snapshot 4482, odyssey 0.5, and gputils 0.13.4.
- The applications size has been optimized.

REST::Application is a framework for building RESTful web-applications.

SYNOPSIS

# MyRESTApp L instance / mod_perl handler
package MyRESTApp;
use Apache;
use Apache::Constants qw(:common);

sub handler {
__PACKAGE__->new(request => $r)->run();
return OK;
}

sub getMatchText { return Apache->uri }

sub setup {
my $self = shift;
$self->resourceHooks(
qr{/rest/parts/(d+)} => get_part,
# ... other handlers here ...
);
}

sub get_part {
my ($self, $part_num) = @_;
# Business logic to retrieve part num
}

# Apache conf
< Location /rest >
perl-script .cgi
PerlHandler MyRESTApp
< /Location >

This module acts as a base class for applications which implement a RESTful interface. When an HTTP request is received some dispatching logic in REST::Application is invoked, calling different handlers based on what the kind of HTTP request it was (i.e. GET, PUT, etc) and what resource it was trying to access. This module wont ensure that your API is RESTful but hopefully it will aid in developing a REST API.
