Silva News Network 2.1 released

Publication date: 15.June.2006, 10:03

14 februari 2006 – Infrae has just released version 2.1 of Silva News Network, the news application and framework for Silva. Silva News Network can be used to turn a Silva site into a sophisticated news publishing and aggregation application.


The most important changes in the new release are:

  • Silva 1.5 support (Silva 1.5 is the required Silva version for SilvaNews 2.1).
  • Added upgrader for a specific Zope 2.8.x issue, where catalog queries failed under certain circumstances (when using Zope 2.7.x contents).

For a full list of changes, see HISTORY.txt in the package.

What is it?

Silva News Network provides a News and 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 might have their own news page too. By adjusting SNN filters, editors can choose what target audiences and subjects their aggregator collects, and have granular control of display down to an article level.

Silva News Network viewers 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. SNN has RSS extensions; a news viewer can publish its contents as RSS. There is also an RSS Aggregator that can be used to pick up and display news from other SNN sources or external RSS and Atom feeds.
