Silva is an open source CMS in use at many institutions, primarily in Europe, but also in the US and Australia. It's a powerful solution for organizations that manage complex websites. Content is stored in clean and futureproof XML, independent of layout and presentation. Features include versioning, workflow system, integral visual editor (Kupu), content reuse, sophisticated access control, multi-site management, extensive import/export facilities, fine-grained templating, and hi-res image storage and manipulation.
Development of Silva began in 2001. Through the support and contributions of many developers it's grown into a robust and stable content management system, especially suitable for use at hierarchical organizations. Today Silva is highly scalable, serving websites with millions of pieces of content and running in clusters that host 350+ Silva sites.
The initial funding for development came from Erasmus University in Rotterdam, the Netherlands. Other investors quickly followed, such as the visionary ETH Zurich in Switzerland (the Swiss Federal Institute of Technology), Wirtschaftsuniversität Wien (the Vienna University of Economics and Business Administration), the University of Bedfordshire in the UK, and many others. Independent developers continue to contribute much to Silva; see the credits file for a list.
Silva is built upon the advanced Zope application server which offers a through-the-web management interface, a flexible templating language, relational database integration besides its built-in object database, security infrastructure, XML support, extensibility with new components, scalability through clustering, and many other things. Zope and Silva are written in Python.
Silva and all of its components are open source with a BSD license.
