| GENERAL DESCRIPTION |
The Data Standardization (DS) Domain Action Team (DAT),
which includes the application developer, identifies which reference files
should be standardized for the Domain. Each entry in the file is then
assigned a VHA Unique Identifier (VUID) by the Enterprise Reference
Terminology (ERT) Group. DS then assists in the seeding of the VUIDs at the
Facilities. There are two approaches to the VUID Seeding. The first is
Facility by Facility and the second is Global Distribution. Additional
information about the approaches can be found in the VUID Implementation
Application Patch Requirements Document for the Domain being Standardized.
Each Domain is given a document which identifies the changes needed in Current
VistA for the DS effort. One of the requirements is to release a VistA patch
via the National Patch Module (NPM) which contains the changes identified in
the Patch Requirements Document.
For the Facility by Facility Approach the HDIS Domain file is used during the
VUID Seeding Process. It contains a list of the files being standardized for
the Domain. The VUID Seeding Process itself is invoked in the application
post-initialization routine by calling EN^HDISVCMR (IA #4639). As part of
this process DS will look through the entries for each of the files being
standardized for the Domain and extract the .01 field to be bundled into an
XML message.
The subscriber agrees to give DS permission to directly access the Global in
the routine FILE^HDISVCFX for the .01 field of the file being standardized.
GLOBAL REFERENCE:
^Global(file#,D0,0)=.01 field read only
