# Silverstripe CMS

Silverstripe CMS is a free and open source content management system (CMS) and framework for creating and maintaining websites and web applications. It provides an out of the box web-based administration panel that enables users to make modifications to parts of the website, which includes a WYSIWYG website editor. The core of the software is Silverstripe Framework, a PHP Web application framework.
Silverstripe CMS is released under the terms of the BSD License.

## Software design

Silverstripe CMS separates the roles of:
* content authors (who get a rich (AJAX) web-based user interface that omits technical jargon); and
* website designers/developers (who write code: HTML, CSS, JavaScript, and PHP)
This contrasts with CMS products which allow technical website development tasks to be performed within a GUI, and also contrasts with programming frameworks which offer no out-of-the-box content authoring application. The Silverstripe CMS approach allegedly removes complexity for content authors, and offers more flexibility to developers.
The core of Silverstripe CMS is named Silverstripe Framework (formerly referred to as "Sapphire"). As with the rest of the platform, it is written in PHP (5.3), and takes advantage of its object-oriented design capabilities such as name-spacing. The Silverstripe Framework provides website developers a framework to build and extend websites based on modern programming techniques including the model-view-controller pattern and object-relational mapper.
Silverstripe CMS generates markup using a custom template-language based on W3C HTML5 that offers simple placeholders and conditional logic. Silverstripe CMS is extensible through modules, widgets, themes and code customization.

## Features

Notable features of the Silverstripe CMS include:
* Out-of-the-box template, supporting responsive design (works on smartphones, tablets, and desktop computers)

* Quick embedding of videos and other resources from websites like YouTube, slideshare, etc. (using oEmbed)

* Optimizations for heavy loads (full and part-template caching)
* Internationalization/Languages: Silverstripe CMS 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 (Linux, Windows, Mac), Web server (Apache, IIS), Database (MySQL, PostgreSQL, Microsoft SQL Server fully supported; SQLite and Oracle Database have limited support.)
Notable features of upcoming releases of Silverstripe CMS 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

## Modules, widgets, and themes

Modules can be used to extend the core functionality of Silverstripe CMS. Some existing modules include: Blog, Advanced Workflow Management, eCommerce, Forum, and LDAP/OpenID authentication. Modules are available from the Silverstripe CMS modules repository, which as of October 2022, lists over 3000 modules.
Silverstripe CMS Widgets are small pieces of functionality that can be drag-and-dropped into Silverstripe CMS modules (notably the blog module). Examples of widgets include: tag clouds, Flickr photos, or word of the day. Widgets are a relatively less-used aspect of the platform. As of August 2012, there are 96 widgets.
The Silverstripe CMS themes directory provides a number of community-contributed, freely available themes (114 as of October 2022).
Modules, widgets, and themes are all available as free downloads under the BSD license, and the majority of them are community contributed.
