Creating a digital library requires converting the original scanned images into various formats. WolfpackSys is a software system that performs these large data conversion tasks in a distributed manner. The framework allows the best off-the-shelf conversion programs to be used in an automated system, and it runs the conversions in parallel on a large number of machines. It is currently used to perform image cropping, de-skewing, de-speckling, and OCR, as well as to create JPEG and Acrobat files from scanned images.

SwiXAT is a Swing-based authoring tool for the quick and easy development of GUI Java applications. It implements a true MVC framework and uses XML to define the view (SwiXML is used as the XUL engine), BeanShell as a scripting language for the controller, and JXPath as the binding mechanism between the view and model. It provides a complete environment in which it is possible to almost write an entire Java Swing application without writing Java compiled code. The use of XPath makes it very simple to traverse the object tree of the application's business model.
