Silva 1.0: The Structured Content Management System

July 20, 2004 - after two and a half years of development, the Silva team is happy to announce the release of Silva 1.0. Silva is an open source content management system with a focus on structured content and its reuse. It is based on the open source web application platform Zope, and the programming language Python.

New in Silva 1.0 are:

  • Deeply integrated support for Kupu, the WYSIWYG through the web editor with support for both Mozilla and Internet Explorer.
  • Silva 1.0 ships with full documentation that is a Silva publication itself. When you install a new Silva root you get the option to install the documentation as well.
  • Other new features include image thumbnail support and image cropping support.

"At ETH we operate a mass virtual hosting Silva instance hosting a few hundred sites," says Reinhard Hess, of the central IT services at the Swiss Federal Institute of Technology in Zurich (ETH Zurich). "In addition to that there are a number of sites being run by independent departemental IT units across the university." ETH Zurich has been deploying Silva since 2002 - and they are also developing on the platform. "Silva is well capable to compete successfully with other web CMS products in the enterprise range - either open source or closed source. Silva was a good choice for us. Silva gives us the best cost/performance ratio even in the long term and maximum operational flexibility."

The University of Luton in the UK is going online with a new Silva-based site later this week. "Silva is a very flexible tool for generating and maintaining web content," says Steve Kendall, University of Luton project manager. "Previously all web content had to be looked after by a small team of central staff with specialised skills, but now we have the mechanisms in place to return full ownership of the content to the faculties and departments."
