openMDWS is Rob Tweed's new all-encompassing strategy for opening up access to VistA.  It embraces and extends the VA's Medical Domain Web Services strategy, casting it as an Open architecture and widening its focus beyond XML-based web services.

EWD is Rob's rapid web development framework which has become the de-facto technology for modernising VistA's UI and allowing to be accessible from desktop browsers and mobile devices.  EWD underpins openMDWS and together they represent a potent and exceptionally productive platform for the VistA developer.

This course is designed for all VistA developers who wish to learn about EWD and openMDWS.

The course will assume no prior knowledge of EWD, openMDWS, MDWS or of web application development.  By the end of the 3 day course, all students should be capable of building openMDWS services and creating desktop and mobile web front-ends for VistA.

The course will start by examining in detail how web applications and web services work and the many critical issues faced by web and mobile application developers that are addressed and automated by EWD.

It will then focus on how EWD works, its design principles and philosophy, before focusing on how it simplifies the use of the very latest breed of Javascript frameworks, in particular ExtJS and Sencha Touch.  It will also look at MDWS and its metamorphosis into the openMDWS architecture.

The next step will be to demonstrate how to design and build openMDWS services on top of VistA, and then examine how EWD can be used in conjunction with openMDWS.

Along the way, students will participate in hand-on exercises.  To this end, all students should come prepared with a laptop and have an installed and running version of the dEWDrop Virtual Machine (  Important Note: there will *not* be time during the course to help with its download and installation.
