JBoss.org Community Documentation
In this chapter you downloaded and installed the example application and used it to upload files into a JCR repository. JBoss DNA automatically sequenced the image and/or MP3 files you uploaded, extracted the metadata from the files, and stored that metadata inside the repository. The application allowed you to see this metadata and the sequencing statistics.
This application was very simplistic. In fact, running through the example probably only took you a minute or two. So while this application won't win any awards, it does show the basics of what JBoss DNA can do.
In the next chapter we'll venture into the code to get an understanding of how JBoss DNA actually works and how you can use it in your own applications.
