6 december 2006 – Infrae has just released Silva News Network 2.6 beta. This is the first Silva 2.x compatible release of SNN.

What is it?

Silva News Network provides a News & Events application for Silva that runs out-of-the-box. It offers the capability to deploy multiple News Sources within an organization, say, in different departments, where some or all sources can be aggregated into a central news page. The different departments can have their own news page too. By adjusting SNN Filters, editors can choose what news sources, target audiences, and subjects their aggregator collects, and have granular control of display down to an article level.

SNN Viewer components can be used ‘as is’ for a news page, or be included inline into a document. Silva templates can display news feeds in a related column. Silva News Network has RSS/Atom extensions; a News Viewer can publish its contents in RSS or Atom format. There is also an RSS Aggregator that can be used to pick up and display news from external RSS and Atom feeds.


Thanks to Andrew Altepeter of Bethel University in St. Paul, USA, and Marc Petitmermet of ETH Zürich, for indefatigable flagging and fixing of issues.  Also thanks to Jon Bowlas at University College London for initial development of the SilvaNewsCategoryFilter.
