This devshare submission qualifies for Plug In 2 BIRT Contest
Dropbox ODA allows BIRT users to create Dropbox usage reports. It doesn’t take too long to fill up a Dropbox, and when you realize you do need to remove some files, it can be difficult to know where to start.
Dropbox ODA provides access to your files using the Dropbox Search Rest API. You provide a query and an optional path (the default is the root), and the ODA provides a rich result set that you can group, sort, chart, etc. This makes it a lot easier to find large files that have been long forgotten.
Please take a look at the User Guide, which has much more detail.
