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:
- A modern, extensible web-application interface
- Drag and drop customization of tree-based navigation structure
- Customizable output markup with CSS-based, table-free defaults
- Work-flow management:Draft/Published separation through content staging, and document revision control/rollback with 'compare' functionality
- Highly configurable security/permissions model
- Data object model, automatic database schema generation, and a suite of CMS data controls to enable easy customization of inputs.
- asset management and image resizing
- Multiple templates per page
- Search engine friendly URLs, meta-data management, and automatic XML sitemap generation
- Full text search and RSS feeds
- Optimizations for heavy loads (e.g. manual cache refresh)
- 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.
Common CMS features not available in SilverStripe include:
- In-place page editing
- Web-interface based installation of Modules, Widgets or Themes
- Web-interface based editing of data model, themes
- Automated cache management/ORM refresh
Modules, Widgets, and Themes
Modules extend the core functionality of SilverStripe. Existing modules include: blog, advanced workflow management, ecommerce, forum, LDAP/OpenID authentication. Modules are available from the SilverStripe modules repository.
SilverStripe Widgets are small pieces of functionality that can be dragged and dropped into SilverStripe modules (notably the blog module). Examples of widgets include: tag clouds, flickr photos, or word of the day.
The SilverStripe themes directory provides a number of community-contributed, freely available themes. These themes can be quickly added to most SilverStripe sites.
Modules, Widgets, and Themes are all available as free downloads under the BSD license, and the majority of them are community contributed.
Software Requirements
SilverStripe is a web application, requiring a compatible HTTP server and SQL database. As of version 2.3.0 (23 February 2008), the requirements for SilverStripe are as follows [1]:
- Apache v1.3.19+, Lighttpd, or Microsoft IIS 5.1+ (A URL Rewriter is strongly encouraged but not required, to provide friendly URLs.)
- MySQL v4.1.X+ (Support for other databases is mentioned in the roadmap)
- PHP 5.2+ with MySQL, GD Graphics Library and Zlib support
Documentation
SilverStripe is released under the terms of the BSD Licence. Documentation is available for CMS users and website developers. An online demonstration of the CMS is available as a video and as an interactive demo. A 450 page technical reference book on SilverStripe is available in German[2]. An English book is available for pre-orders, with publication scheduled for August 2009.[3]
History
The SilverStripe software is developed by SilverStripe Limited, a website development company founded in 2000.
Prior to SilverStripe 2.x, the CMS was commercially available under a proprietary license. Development of SilverStripe 2.X started in late 2005, as a complete overhaul to take advantage of object orientation and new features in PHP5.
On 3 February 2007, SilverStripe 2.0.0 was released publicly as free and open source software[4].
In March 2007, SilverStripe was selected for the Google Summer of Code programme[5]. This programme resulted in the 2.2 release of SilverStripe[6].
On 29 November 2007, SilverStripe announced they would be participating in the Google Highly Open Participation (GHOP) contest[7]. This led to a proliferation of themes, translations and widgets that broadened the system.
In late 2008, SilverStripe split its main website into silverstripe.com, to act as the home for the company behind the software, and silverstripe.org, to act as the home for the software and its open source community.[8].
In April 2009, SilverStripe claimed the software had been downloaded 150,000 times since first released[9].
In May 2009, the SilverStripe company formed partner associations with other website development companies to represent the company in foreign markets[10].
