The document introduces the IKS project, which aims to develop a reference architecture for semantically enabled content management systems. It describes key components of the IKS technology stack including the Apache Stanbol framework for semantic enhancement and reasoning, and the VIE library and widgets for building semantic user interfaces. The document provides overviews and examples of each major component in the IKS stack.

What is a Semantic CMS?
Traditional CMS vs. Semantic CMS
 Atomic unit: Document  Atomicunit: Entity
 Properties as meta-data  Semantic meta-data
 e.g. author  Defined entity types
 tags, keywords  Linked entities
 Keyword search for  Semantic search for
 strings in docs  entities and their relations
