The document discusses using the Java Content Repository (JCR) specification and REST web services to build non-CMS web applications that access content in a flexible and standardized way. It provides an overview of JCR and how the Apache Sling framework uses JCR and REST to easily create dynamic websites and applications using content from a JCR-compliant repository without the need for server-side programming. Code snippets are included that demonstrate performing basic CRUD operations on content from a JCR repository using RESTful URLs and JavaScript.
