This release contains four packages. A single "CACHE.DAT" file of the routines and data as one complete instance, an archive containing the routines available as individual files, an archive containing a global export of all data, and a zip archive containing the images attached to patient records in the demo dataset. The varying formats are provided to give adopters a choice of database engines. We have provided no instructions on how to install, import, setup, start or use OpenVista. Guides for installation exist elsewhere.
