JCR (Java Content Repository)

A Java Content Repository (JCR) is a standardized way for applications to store, organize, and retrieve digital content, such as documents, images, or web pages. It provides a structured, hierarchical system similar to a file directory but with advanced features like versioning, search, and access control. JCR enables different software systems to manage content consistently and efficiently, making it easier for developers to build, share, and maintain content-driven applications without needing to create custom storage solutions. Essentially, it acts as a universal content management framework for Java-based systems.
