JSR 170 provides a standard API for accessing content repositories in a technology-agnostic way. It allows different systems like content management, product lifecycle management, and learning management systems to share content repositories. The API provides hierarchical navigation of nodes and properties, as well as features like versioning, transactions, and access control. Implementations like Apache Jackrabbit provide a full-featured open source content repository that complies with JSR 170.
