Web Apps atop a Content Repository
Download as PPTX, PDF0 likes1,149 views
The document discusses content repositories like Apache Jackrabbit and web frameworks like Apache Sling. It explains that Jackrabbit is a Java content repository API that provides structured and unstructured content storage, properties, versioning, and access control. Sling is a web framework that is built on top of content repositories, implements OSGI, and offers scriptable application layers, RESTful capabilities, and extensibility through OSGI bundles. The combination of Jackrabbit and Sling aims to meet challenges of web application development by enabling rapid prototyping, high dynamism, maintainability, and a REST architecture.
