Apache Sling is a RESTful web framework built on top of the Java Content Repository (JCR) standard. It maps HTTP requests to content resources using a resource-oriented URL decomposition model and uses scripts or servlets to render responses, supporting multiple scripting languages including HTL, JSP, Groovy, and server-side JavaScript. Apache Sling forms the foundation of Adobe Experience Manager (AEM) and is an Apache Software Foundation project with 300+ modular OSGi bundles.
