- 9. Community Validation On Medsphere.org: “which is the best community site in the health FOSS industry” On Medsphere’s open development and expertise: “we need to fully endorse whatever party is actually making progress on the problem. So far, that is Medsphere. In open source doers rule.” – Fred Trotter, O/S Health Advocate and ‘Hacktivist’ 9 Copyright © 2010 Medsphere Systems Corporation
- 10. Fostering an Active Community Black Duck Software, which maintains a knowledgebase of more than 200,000 open source projects, recently announced results of research focused on open source healthcare software. They listed the top 10 healthcare projects, of which VistA was one. Black Duck also identified healthcare software projects where community contributions are strongest: "Projects dealing with electronic health records management, practice management and VistA, the health care information management system developed by the US Veterans Administration, lead in project community activity. OpenVista, an open-source version of VistA, is among the most active health care projects in the open source community as tracked by the Black Duck KnowledgeBase." 10 Copyright © 2010 Medsphere Systems Corporation
- 11. OpenVista Server OpenVista Server is derived from the VA Freedom of Information Act (FOIA) VistA server release and includes defect corrections and a selection of commercial enhancements equivalent to what has been released at Medsphere client sites.

- 23. In January of 2010, Conestoga College embarked on a project to integrate openDICOM.net with OpenVista CIS in order to better support their research and educational pursuits within the Center for Clinical Simulation. A workable plug-in was built within four Plug-in Support – months, including interfacing to the image database.

- 27. OVID The OVID (OpenVista Interface Domain) layer is a set of development tools designed to enable software developers easier access to OpenVista data and applications. OVID is a foundational technology that allows developers to build upon OpenVista (and VistA derivatives) using alternative languages (such as Java) or architectures (such as Web Services/SOA).

- 28. OVID Technical Capabilities • Useful for building on the OpenVista/VistA platform: Traditional applications Web/Mobile applications Exposing OpenVista data/logic as Web Services Console based applications Automation and Integration • Ability to create M to Java calls, allowing M applications to call external Java APIs • Ability to create Java to M calls, allowing Java applications to call into M APIs • Supports creating Java domain objects 28 Copyright © 2010 Medsphere Systems Corporation
- 29. A Platform Using the OVID technology and framework, community contributors and Medsphere have created new tools and applications: Web Services to CCR/CCD gateway Web Services to DoD KMR middle tier IHS/Medsphere Clinical Flowsheet, Pharmacy and more in development iPhone/iPod application to view patient record in real-time Registration application built on OVID RESTful interface to OpenVista 29 Copyright © 2010 Medsphere Systems Corporation
- 31. Web Services via OVID • Sample web services published • Source available • See “Creating Web Services with OVID” 31 Copyright © 2010 Medsphere Systems Corporation
- 32. When to consider OVID VistA provides a strong integrated solution ...but, Integration is a double-edged sword VistA has not easily adapted to the changing world OVID can be used in projects with varying goals: • Extension – or a platform on which to build • Integration – the glue between disparate systems • Orchestration – conducting between systems • Migration – a transitional path to different technology See: Extending the Platform talk, 6/9 @ 9am 32 Copyright © 2010 Medsphere Systems Corporation
- 33. FM Projection FM (File Manager) Projection is a technology that “projects” the data structure of OpenVista into a relational database format. Users can query against FM data structures using SQL queries and COTS query tools.

- 34. FM Projection Architecture: • M-engine agnostic (GT.M or Cache) • Implements a MySQL storage engine that is backed via a network connection to an OpenVista server • Projection model uses SQLi package Capabilities: • Data can then be accessed via J/ODBC data tools and compatible data access development libraries • A Java-based schema and data viewer is included • Current version provides read-only access Uses: • Connect open source or COTS data analysis, reporting, BI tools 34 Copyright © 2010 Medsphere Systems Corporation
- 35. GT.M Integration Project The OpenVista/GT.M Integration Project has released Linux tools and enhancements to OpenVista to meet production environment requirements. The project strives to re-use as much existing infrastructure as possible, encourage best practices by building them into tools, and be familiar to Linux administrators and M/VistA users alike.

- 36. Project History Medsphere had been using GT.M internally for development, QA, and open source efforts for a number of years • Installation and operation required strong knowledge of Linux • Installations were not repeatable • Incompatibilities with VistA OpenVista/GT.M Integration project started in late 2008 • Published proposals and gathered community and internal requirements and feedback • All bugs and code published on Launchpad.net • Initial release May 2009 • Regular releases every month or two 36 Copyright © 2010 Medsphere Systems Corporation
- 37. Project Goals OpenVista, GT.M, and Linux make up a pure open source stack, but they were not specifically designed to work with each other. There is significant value in integrating these components to simplify installation and management. • Packaging Should be able to “apt-get install openvista” Packaging should follow OS/package management standards • Management tools Install, backup, restore, and monitor OpenVista instances easily Access instances securely Handle journaling and boot/shutdown tasks automatically • Platform port of VistA/OpenVista to GT.M Error trap, HL7 and RPC broker management, printing, routine management, switching between instances Find and fix Cache-specific/non-standard M 37 Copyright © 2010 Medsphere Systems Corporation
- 38. Future Development Package more components • OVID • Mirth • OpenVista Server Wrap more GT.M functionality • Replication • Database encryption • Shared objects on x86_64 Deeper integration with OpenVista • Developer tools • Initial configuration Volume set, RPC Broker, TaskMan • Adding printers CUPS, DEVICE file 38 Copyright © 2010 Medsphere Systems Corporation
- 39. Other Releases Medsphere.Widgets is a collection Strongwind is a GUI test of cross-platform interface automation framework inspired by elements for Gtk# used by dogtail. Strongwind is object- Medsphere's products — primarily oriented and extensible. You can OpenVista CIS. Some are a use Strongwind to build object- compositions of standard Gtk# oriented representations of your widgets, and others, like GridView applications ("application and Graph, are custom managed wrappers"), then reuse the widgets. application wrappers to quickly http://medsphere.org/community/project/medsphere-widgets develop many test scripts. Strongwind scripts generate a human-readable log that contains the action, expected result and a screen shot of each step. http://medsphere.org/community/project/strongwind 39 Copyright © 2010 Medsphere Systems Corporation
