Umbraco is an open source content management system (CMS) platform for publishing content on the World Wide Web and intranets. It is written in C# and deployed on Microsoft based infrastructure. Since version 4.5, the whole system has been available under an MIT License.[3]

Umbraco was developed by Niels Hartvig in 2000 and released as open source software in 2004.[4] In 2009, CMS Wire described it as one of the leading .NET-based open source CMS systems.[5][6] In 2010, with 1000 downloads a day,[7] Umbraco was in the top five most popular downloads via the Microsoft Web Platform Installer, two places below its main rival DotNetNuke,[8] and was the 12th most downloaded application from Codeplex, six places below DotNetNuke and 13 places higher than mojoPortal.[9]

Technology

Umbraco is primarily written in C#, stores data in a relational database (commonly Microsoft SQL Server) and works on Microsoft IIS. Umbraco's front-end is built upon Microsoft's .NET Framework, using ASP.NET.

Umbraco uses standard ASP.NET features such as ASP.NET "master pages" to facilitate the creation of reusable page layouts, and supports both Razor and XSLT. XSLT has been used for scripting, and in the past there was much debate as to which yielded better performance, since XML has been used for database storage and for the cache file (umbraco.config) [10][11]

Database tier

In 2008, a data abstraction layer for Umbraco was built, making it possible to support databases other than SQL Server. In version 4.0 of Umbraco, support for MySQL, SQL Server and VistaDB come as standard.[12]

With Umbraco 4.6, released in 2010, VistaDB support was removed, and replaced with support for SQL Server Express and SQL Server Compact Edition, due to licensing issues with VistaDB's parent company.[13]

As of Umbraco 6, support for MySQL has waned, as the development team has spent more time supporting Microsoft's SQL Server products.[14] MySQL 5.6.5 or newer is required to support Umbraco 6.1 or newer.

Umbraco 7 featured a completely revamped back-end administration UI, with the use of AngularJS for a single-page application experience. It has also been announced that they will implement AngularJS 2.0.[15]

Deployment

The standard release of Umbraco is typically deployed on IIS in an environment which supports Full Trust. While a Full Trust environment is mandatory to install and operate the standard release, the codebase has been branched and modified to produce a version of the framework and backend UI which supports Medium Trust.[16][self-published source?]

Research has also been undertaken on running an Umbraco website on Mono on Linux.[17][18]

Umbraco can be deployed on a single physical server running the database and web tier, and this deployment model can be appropriate for small low-cost sites. Umbraco sites which serve content under higher load can also be deployed on a load balanced cluster. Load balanced Umbraco installations can use software or hardware load balancers, and load balanced network files can be shared using a SAN, NAS or a cluster file system or using a file replication service between nodes in the cluster.[19][self-published source?]

Releases

Version 4.1 Beta II was released on 16 February 2010 which refactors a number of key components of the framework,[7] including the UI tree control to improve performance and the user experience and parts of the data access layer to reduce the number of database calls.

Version 5 (codenamed "Jupiter") is a rewrite of the framework, built using ASP.NET MVC,[20] published in January 2012. Problems (performance and code complexity) inherent in the architecture of the new Version 5 data access layer [21] led to Version 5 being dropped in June 2012 despite having been released on a commercial licence,[22] and development efforts refocused on integrating selected Version 5 front end enhancements into Version 4.

Version 6 was released on 31 January 2013, and was focused on additional support for MVC 4 and a new streamlined API.[23]

Version 7 was released 21 November 2013. It is updated concurrently with version 6, but provides a redesign of the back-office user interface.[24]

Community

The Umbraco corporation employs a staff of 9[25] and is supported by a core development team of 15[7] volunteers who work on the open source core platform. Umbraco's community site, "Our Umbraco", has more than 55,000 registered users and developers.[citation needed] Since 2005, an annual developer conference has taken place in Copenhagen, except in 2007, when it was held in London. In 2009, the conference had 170 attendees[citation needed] and subsequently took place in Copenhagen in June 2010[26] and June 2011, then growing to 350 attendees for June 2012 and 2013.[citation needed]

Reception

In August 2009, Umbraco was included in a list of 10 CMS systems recommended by the Danish Version2 magazine. Among these were three systems initially developed in Denmark: Sitecore, TYPO3, and Umbraco.[27]
