A growing number of countries around the world have introduced legislation which either directly addresses the need for websites to be accessible to people with disabilities, or which addresses the more general requirement for people with disabilities not to be discriminated against. TYPOlight does not treat accessibility as just an additional feature and is thoroughly accessible.

Elgg is an open, flexible social networking engine, designed to run at the heart of any socially-aware application. Building on Elgg is easy, and because the engine handles common web application and social functionality for you, you can concentrate on developing your idea.

Elgg is open source. That means, when you use Elgg, you have the benefit of being part of a large developer community, with the security and stability that hundreds of eyes can provide. It’s also headed and used by Curverider and its partners, so you can be assured that it’s in commercial use and will cope with the demands of a popular application. 

It runs on Apache, PHP and MySQL – the same open source platform that the majority of web applications are written in. Elgg is compatible with enterprise technologies like the Zend Platform and any server environment that can run the Apache web server.

Elgg supports

• User, object, file and site management

Symphony has a bucket-load of features, but rather than tell you about them all, it’s better to let you discover them for yourself. Check out the live demo or download the Symphony installer and try it for yourself. Below is an overview of Symphony’s main features.

Designed to do things your way

Symphony lets you organise everything the way you like, from your publishing environment to your website’s URL structure. Built to be versatile and customisable, Symphony really is what you make of it.

Powered by XML and XSLT

Symphony’s templating engine is pure XSLT goodness. XSLT is a standard recommended by the W3C, so learning Symphony means that you’re learning skills that you can also use outside of the system. If you already know the XML and CSS standards, then chances are you should be able to quickly pick up XSLT.

Symphony allows you to create small blocks of XSLT code called utilities, which you can use as building blocks to construct your site’s pages. Due to the nature of XSLT, these utilities are highly reusable, so the next time you’re developing a website you’ll probably find you’ve already done half the work.

There’s no need to bother with complex SQL queries; Symphony can take care of the heavy lifting while you just worry about what data you’d like. Of course, if you want to write the queries yourself (or maybe a PHP event on page request), you can.

Rapid developement means more time to relax

It takes 4 minutes to setup and install Symphony. It takes 3 clicks to install Campfire services (our extension system), 2 clicks to update the system and 1 click to get the latest stats on your website. Symphony is about getting things done quickly.

Features

The Engine

• Symphony is modular, which makes it a cinch to move your files between different websites, collaborate on a single project and share themes with the Symphony community.
• Of course, if there is something Symphony can’t do, there’s no problem. Campfire services, Symphony’s extension modules, can add extra functionality where it’s missing.

The User Interface

• By making every aspect of the publishing environment customisable, Symphony gives you complete control over how you and your authors publish. Every field is customisable and reorderable, and you can even apply validation rules which make sure they are correctly formatted.
• You can manage everything from within the admin interface, but Symphony is also designed to work with FTP, so if you’d rather edit files directly on the server or with your favourite text editor, you can. All your changes will be reflected in Symphony and on your website immediately.
• Symphony’s XML-RPC Campfire services allows desktop applications like MarsEdit to publish entries to your website remotely.

The Development Environment

• Maintenance mode is very useful for testing and debugging a live site. Switch on maintenance mode and visitors will be directed to your maintenance page, while you can still see and browse your website as normal. A set of handy debugging features are also enabled during maintenance.
• URL schemas give you a clean and efficient way to create dynamic pages.
• Did we mention that XSLT is a very cool templating language?

Requirements

Your Server

• PHP 4.3
• MySQL 3.23 and above
• XSLT Support (LibXSLT or Sablotron)
• Some common modules: XML Support (LibXML), ZLib Compression Library and mod_rewrite Apache module

Your Browser

• The Symphony admin requires that you use a modern standards-compliant browser. We recommend Firefox and Safari.
• For the best experience, make sure you have cookies and JavaScript enabled.

Based on the best practices of web development, thoroughly tried on several active websites, symfony aims to speed up the creation and maintenance of web applications, and to replace the repetitive coding tasks by power, control and pleasure.

Symfony provides a lot of features seamlessly integrated together, such as:

• simple templating and helpers
• cache management
• smart URLs
• scaffolding
• multilingualism and I18N support
• object model and MVC separation
• Ajax support
• enterprise ready

New Features in 1.0

• Easier installation and larger compatibility. Symfony is now compatible with magic_quotes_gpc set to on and PHP 5.2. Pake and phing are now bundled with the core classes, so symfony has no more external dependency. It is very easy to link a symfony application to the symfony libraries (through the config/config.php file), and PEAR is no more a prerequisite. The symfony command line now works out the box (for PEAR, SVN or .tgz).
• Major performance improvement. Many parts of the code have been refactored, with performance in mind. The result is a performance increase of 50% to 500%, depending on your platform.
• New plugin system. Extending symfony has never been easier. A plugin can package classes, modules, helpers, filters, web assets, fixtures, data models, unit tests, and so on. Plugins can be installed with one command. Check the Plugins page for a list of already available plugins.
• New unit test library. Symfony is now bundled with its own unit and functional test framework, called lime, and a bunch of automated tests utilities, such as the sfTestBrowser and sfDomCssSelector classes. Symfony itself has more than 2800 unit and functional tests that guarantee its quality of code.
• Updated default pages for error 404, error 500, insufficient credentials, unavailable page, and deactivated application (thanks justinm for the design!). These pages are both much nicer and much easier to customize than before.
• Easier templating. Components and components slots now work perfectly on every situation, even with cache set to on. Their code was refactored to be fast and effective. The new temlate fragment tools, called slots, are faster than component slots, require no extra file or configuration to add a dynamic zone to a layout. And the icing on the cake: Ajax actions have no layout by default.
• Better and more flexible Model layer. Symfony is now ORM independent: it is still bundled with Propel by default, but can work with others (such as Doctrine) in a snap. Database schemas can now be written in YAML instead of XML. Persistent support and specific database encoding are now supported natively.
• New mixin feature. The sfMixin class introduces mixins in PHP, allowing core classes modification without inheritance, addition of new methods to existing classes, and multiple inheritance.
• New behaviors for Propel classes. A behavior is a group of properties and methods that can alter the Propel generated classes. To make a Propel class sortable, to add a pessimistic lock, or to change the deletion by a is_deleted flag, you now need only one line of code with behaviors.
• More user-friendly development tools. The symfony logs and the web debug toolbar now display more information about time and execution bottlenecks, thanks to the new sfTimer class. The symfony command line now has a color output (in *nix). The logging mechanism (via the sfLogger class) is more flexible and easier to extend. Logs rotation and cleaning are automated.
• More flexible filter system. User filters can now be registered anywhere in the filter chain (even before the security filter).
• New many-to-many relationships are now supported in the admin generator.
• Easier deployment. The freeze task is implemented and fully functional. It transforms a symfony project into a self sufficient program by adding in the symfony libraries and assets.
• Updated creole, Propel, script.aculo.us (1.6.5) and prototype (1.5.0_rc1)
• And more than 200 bug fixes and small enhancements
