Blog:CMS (formerly Nucleus XE) is a content management system written in PHP with a MySQL database. It attempts to integrate several open-source projects into a forked version of Nucleus CMS, including DokuWiki, PunBB, and an image gallery, using modifications written by its primary developer, Radek Hulán. The project is generally considered a “pre-modded version” of Nucleus CMS, rather than a full product in its own right. The Blog:CMS home page claims that it is used on thousands of websites worldwide.

concrete5 is an open source content management system (CMS) for publishing content on the World Wide Web and intranets.

It enables users to edit site content directly from the page. This makes the platform easy to use with a minimum of technical skills. This feature, combined with a version management for every page, are typical of wiki software, another type of web site development software. concrete5 allows users to edit images through an embedded editor on the page.
Concrete5 was chosen as SourceForge’s “Project of the Month” October 2008.

Features

Concrete5′s main feature is in-context editing (the ability to edit website content directly on the page, rather than in an administrative interface or using web editor software). Editable areas are defined in concrete5 templates which allow editors to insert ‘blocks’ of content. These can contain simple content (text and images) or have more complex functionality, for example image slideshows, comments systems, lists of files, maps etc. Further addons can be installed from the concrete5 Marketplace to extend the range of blocks available for insertion. Websites running concrete5 can be connected to the concrete5 website, allowing automatic upgrading of the core software and of any addons downloaded or purchased from the Marketplace.

SilverStripe is a free and open source content management system (CMS) for creating and maintaining websites. The CMS provides a web-based administration panel that enables users to make modifications to parts of the website. This panel includes a WYSIWYG website editor.

SilverStripe is released under the terms of the BSD Licence. An online demonstration of the CMS is available as a video and as an interactive demo. Documentation is available for CMS users and website developers.

Software Design

SilverStripe is written in PHP5, and takes advantage of PHP5′s object-oriented design capabilities. It is based on a model-view-controller pattern and uses an object-relational mapper. The CMS generates markup using a custom template language. SilverStripe contains Sapphire – a custom PHP framework.

SilverStripe is extensible through modules, widgets, themes, customization and ModelAdmin. SilverStripe generally relies on a code customization model over configuration.

Features

Notable features of the SilverStripe CMS include:

• An extensible web-application interface
• Drag and drop tree-based navigation structure
• Custom output markup and table-free default styles (including HTML5 support)
• Work-flow management: Draft/Published separation through content staging, document revision control/rollback with ‘compare’ functionality
• Configurable security/permissions model (role-based)
• Data object model, database generation through [object-relational mapping], suite of customizable data input controls.
• asset management, image resizing
• Multiple templates per page
• Search engine friendly URLs, meta-data management, XML sitemap generation
• Full text search and RSS feeds
• Optimizations for heavy loads (full and part-template caching)
• Internationalization/Languages: SilverStripe supports multiple-language content. UTF-8 and the internationalization of character sets are supported. The CMS is available in many languages, including English, French, German, Spanish, and Chinese.
• Hierarchical URLs
• Cross platform: OS (Windows, Mac, Linux), Web Server (Apache, IIS), Database (MySQL, Microsoft SQL Server, PostgreSQL fully supported; SQLLite and Oracle have limited support.)

Notable features of upcoming releases of SilverStripe include:

• Additional Administration UI (e.g. Web-interface based installation of Modules, Widgets)
• Complete transition to jQuery library (currently uses jQuery with a mixture of older JavaScript frameworks.)
• Site-wide Widgets

Common CMS features not currently available in SilverStripe include:

• In-place page editing
• Web-interface based installation of Modules, Widgets or Themes
• Web-interface based customization of themes
• Automated cache management/ORM refresh

Dotclear is an open source blog publishing application distributed under the GNU GPLv2. It is relatively popular in French speaking countries, where it is used by several major blogging platforms. Developed originally by Olivier Meunier from 2002, Dotclear has now attracted a solid team of developers. The latest release of Dotclear is version 2.1.6, released on October 1, 2009.

Dotclears proposed aim is to develop a software fully respecting web standards based on open source solutions with a multilingual capability for publication and for the interface. It is written in PHP (working with version 5.0 or higher) and proposes a choice of databases (SQLite, PostgreSQL, …).

Dotclear is offered as a free blogging system for all hostnames registered with Gandi.net, which guarantees a large number of users in Europe (24,421 as of 2010-02-07).

Frog CMS is an open source content management system originally developed by the company Philippe Archambault. The design decision taken from its start was to use PHP5 as the language for the software, along with a MySQL database backend, although it also has support for SQLite (version 3). It is a port of the Ruby on Rails CMS known as Radiant, although Frog has begun to take its own development direction.

Features

Frog CMS offers the common advantages being based on the well-known PHP/mySQL pair. Resisting the temptation to develop its own arcane scripting system, PHP is available directly to developers, but may be hidden from users. It also makes use of an “Extra Light PHP Framework” to provide some commonly used functions to the CMS. Otherwise, its main features include:

• simple hierarchical structured page creation and navigation
• drag-and-drop page re-ordering
• styles and metadata assigned globally or on a per-page basis
• flexible page content with reusable “snippets” (header, footer), or sidebar, or extended (custom fields) content
• lightweight core with many functions available as “plugins”, including file-management, comment forms, Textile and Markdown support, and database connectivity via PDO (required for use with SQLite); user-contributed plugins include the TinyMCE and FCKeditor wysiwyg editors, gallery, and lightbox-style image display
• user management, allowing three levels of access (“Administrator” = full site access; “Developer” = complete access except to the “User” module; “Editor” = access only to unprotected pages) to the backend; pages can be selectively “protected” from those with “Editor” rights
• built-in CSS editing
• UTF8 encoding, with i18n modules currently available for Bengali (Bangla), Chinese, Croatian, Czech, Danish, Dutch, Estonian, French, German, Hungarian, Indonesian, Italian, Japanese, Norwegian, Polish, Russian, Spanish, and Swedish.
