The Java Content Repository (JCR) standard defines a content model and API for accessing and manipulating content in a content repository. Several content management systems are based on the JCR standard, including:
Apache Jackrabbit: Apache Jackrabbit is a fully compliant implementation of the JCR standard. It provides a hierarchical data storage system that can be used as a standalone content repository or integrated into other applications.
Magnolia CMS: Magnolia CMS is an open-source content management system that is built on top of the Apache Jackrabbit content repository. It offers a range of features for content management, personalization, and e-commerce.
Hippo CMS: Hippo CMS is another open-source content management system that is based on the JCR standard. It offers a flexible and scalable platform for managing digital content across multiple channels and platforms.
ModeShape: ModeShape is an open-source content management system that is built on top of the JCR standard. It provides a flexible and extensible platform for managing content and integrating with other systems and technologies.
Adobe Experience Manager (AEM): AEM, as we have discussed earlier, is another content management system that is based on the JCR standard. It offers a range of features for managing digital content across multiple channels and platforms.
These are just a few examples of content management systems that are based on the JCR standard. The JCR standard is an important part of the Java technology stack and is used by many other systems and applications beyond content management.
