  3. Action Items: review open action items
  4. Discussion: OSEHRA/VistA Product Definition and Roadmap

As a contract deliverable, OSEHRA must define its "Product Definition and Roadmap".  In discussion with the OSEHERA technical team and the OSEHRA Architecture Workgroup (AWG) the following consensus approach was agreed upon:

Class 1: modules are in all VA VistA builds.

Class 2: VA regional customizations of VistA; there are 4 geographic regions and 1 administrative “region”

Class 3: Hospital specific code, templates, files and tables used in local builds; reportedly, there are 5,000 to 10,000 Class 3 modules.

"Product Definition (PD)" is the inventory of modules which comprise OSEHRA/VistA, where:

  • The FOIA release is the “core” set of modules.
  • The PD flags FOIA modules no longer used by the VA (e.g., HealtheVet GUI)
  • The PD includes non-mumps modules used by the VA with appropriate comments.
  • The PD includes non-FOIA, open-source and commercial modules used by the VA with appropriate comments/links.
  • The PD includes the 4 regional and 1 administrative class 2 modules with appropriate comments.
  • The PD includes “VA approved” class 3 modules used by individual hospitals with appropriate comments/links.
  • The PD includes re-factored and in-flight modules with appropriate comments.
  • The PD includes the Cache environment & related modules as the primary VA platform.
  • The PD includes the GT.M environment & related modules as the available open-source platform.
  • The PD includes links to the Visual Cross Reference tool, source code/package directory, documentation Wikis, discussion groups, tests and entries per package.


For each module, The PD defines:

  • Module grouping (e.g., Clinical, Admin/Finance/ HealtheVet)
  • Class (e.g., 1, 2, 3)
  • Core FOIA (yes/no)
  • Module Name
  • FOIA Package Name)
  • Version
  • Namespace
  • Patch Number
  • Public ICR
  • Comment


The Product Roadmap will be defined in 2012 to include:

  • Modernization of VistA (main road)
  • Better GT.M support (branch)
  • VA hospital definitions (branch)
  •  Interoperable EHR (iEHR) transition (branch)
  • vendor code alternatives/unification (branch)
  • Other branches, if appropriate.
