Daisy is a CMS framework.
What sets Daisy apart is its ReST style of WebServices, which allows you to access the standalone repository server through HTTP/XML. Additionally, it comes with a high-level (remote) Java API that's easy to use, regardless of your technical background. Its extensive browsing and editing capabilities are thanks to the DaisyWiki application running inside Apache Cocoon.
Daisy's licensing arrangement is commercially-friendly, so you can use it without worrying about legalities. If you need help with Daisy or want to explore its potential, Outerthought offers commercial services that can meet your needs.
