Apache Forrest is a web-publishing framework based on Apache Cocoon. It is an XML publishing framework that allows multiple types of data-files as input, such as various popular word processing and spreadsheet files, as well as two wiki dialects. Plugins are available to support additional formats, both for input as well as output (such as PDF).
Forrest is not a content management system (CMS), as it lacks the full workflow and admin functions of a CMS. Its primary use is in integrating and aggregating content from various sources and presenting them in a unified format for human consumption.
