Omeka

The Omeka team recently announced the release of Omeka 2.1. Omeka is a free, flexible, and open source web-publishing platform for the display of library, museum, archives, and scholarly collections and exhibitions. The focus of this new version of Omeka is interoperability with other systems by including an API for reading and writing information in your Omeka installation.

According to Patrick Murray-John, Omeka Development Team Manager:

This week we added three Web applications to our CMS Focus top 30 list.  The CMSs and ECMs listed in CMS Focus are not necessarily the most popular in content management and are not meant to meet everyone's requirements for a CMS. Instead the content management systems that make up this top 30 are what I consider content management "game changers" or "attention getters". New to CMS Focus are the following CMS/ECM: EPiServer, Umbraco, and an unknown CMS called Omeka.
