Hi there !
I am very happy to announce the first public release of Zena, a Ruby on Rails CMS on which I started working in 2005.
Since these early days, Zena has grown from a “website with content management” (think wordpress) to a framework to build complex agile applications.
The data model in Zena is built in such a way that database design can be easily altered through the application’s life cycle: it offers both a “document model” (properties) and a “relational model” (SQLiss query language, indexing, scope indices, etc).
I know the “beginner” documentation is sparse, so please do not hesitate to spam me or Zena’s mailing list (http://zenadmin.org/community).
