OSEHRA VistA

This source tree contains patches, tests, and tools for VistA, the Veterans Health Information Systems and Technology Architecture. It is maintained by OSEHRA, the Open Source Electronic Health Record Alliance.

This version of VistA includes Open Source Community contributions accepted by OSEHRA.

Purpose

The OSEHRA VistA-M Source Tree contains a static representation of VistA. VistA is built on a database platform that houses both code and data so it requires programmatic operations to apply changes while maintaining consistency. Patches in this source tree may be applied to a running VistA instance to keep it up to date.

Layout

The source tree is organized as follows:

  • Packages.csv: A spreadsheet recording VistA packages. For each package it has a name, namespaces, file numbers and names, and a directory name for this source tree.
  • CMake: CMake build system modules.
  • Documentation: OSEHRA VistA documentation pages.
  • Scripts: Contains scripts to process VistA patch files, populate the Packages/ directory layout, analyze dependencies, and compute an order for patch installation.
  • Packages/<package>/Patches/<patch>/: Holds distribution files for one patch. The <package> directory name matches that in Packages.csv. The <patch> directory name is derived from the patch build name. For example, directory Packages/Kernel/Patches/XU_8.0_431 holds files for KERNEL patch XU*8.0*431.
  • Packages/Order Entry Results Reporting/CPRS: Delphi sources for the "Computerized Patient Record System".
  • Packages/RPC Broker/BDK: Delphi sources for the "Broker Development Kit".
  • Packages/MultiBuilds: Holds distribution files for multi-build patches. Since these may contain builds from multiple packages we do not keep them under a specific package directory.
  • Packages/Uncategorized: Holds files with no clear package category. In addition, it contains *.csv spreadsheets derived from the VA FOIA Spreadsheets. See Scripts/HowtoUpdateSpreadsheets.rst to update them.
