The document describes the Information Workbench, a self-service platform for developing linked data applications. The key points are: 1. Developing linked data applications is challenging due to issues like integrating diverse data sources and ensuring data and interface quality. 2. The Information Workbench addresses these challenges by providing semantics-based integration of public and private data sources, intelligent data access and analytics tools, and a collaborative authoring environment. 3. The platform uses a self-service model where users can provision instances in the cloud, discover and integrate relevant linked open data sources, customize interfaces using semantic widgets, and extend the platform with their own components.
