Announcing the VistA Novo Project

A new OSEHRA open source project has just been launched to create an open source toolkit developers can use to build VistA-based applications using mainstream development environments. The project, called VistA Novo, will initially focus on supporting JavaScript (using node.js)—additional environments that could be supported in the future include Ruby on Rails and Python.

Visualizing worldwide installations of VistA

Working with data provided by Open Health News we developed a visualization of the worldwide installations of VistA.  The visualization was developed using Google's WebGL Globe open platform.  To view the visualization you'll need to use an updated version of Chrome, Safari or Firefox.  The visualization will not work in Internet Explorer.  To view the visualization, go to

OSEHRA Automated Patching framework for VistA Development


KIDS (Kernal Installation & Distribution System) is a standard way of sending and loading patches and packages in VistA. Because the way patches are constructed and distributed, every patch might have specified dependencies and may only apply in a specific order.

Automated VistA installation and testing using Vagrant

I've been working on an exciting project that will make fresh VistA instance creation and development environment configuration and setup as easy as typing "vagrant up" into a clone of the OSEHRA VistA repository.

VistA patch available from OSEHRA.

In late July, a possible VistA security vulnerability was discovered as part of an academic exercise at a major university.  The VISTA Expertise Network validated the vulnerability for some VistA configurations, and contacted OSEHRA to coordinate a community response.  A special open-source project group was formed.  Operating under non-disclosure agreements (industry best practice in handling zero-day exploits), OSEHRA members and collaborating partners (including VA and IHS) worked jointly to create and test an applicable patch.
