Exploring the Jackrabbit Java Content Repository
Databases and conventional data structures are not always a perfect solution for web development. A web application, such as a staff portal on an intranet, for example, has specific requirements for how and when users can access the data. Users have different needs with respect to the data as well. For example, some are interested in targeted content searches, whereas others want to be notified when significant events occur, and all users need access privileges to modify content.
To put it in more general terms: Simply providing content is not enough. Today's users – and today's web developers – expect that various services will accompany the content. For example, web applications often rely on access controls, search functions, and versioning, and, although the developer could build these functions into the application from scratch, the economies of the programming profession cry out for a more efficient approach.
The idea behind the Content Repository API for Java Technology (JCR) is to abstract data-related services from the underlying application and use a standard API to access these service. A content repository avoids the need to continually re-implement data services with each application. Instead, the application simply calls a function through the repository API.
