0. INTRODUCTION
This specification provides the definition of the Data
maintenance request definition message (DMRDEF) to be used in
Electronic Data Interchange (EDI) between trading partners
involved in administration, commerce and transport.
1. SCOPE
1.1 Functional Definition
This Data maintenance request definition message (DMRDEF)
permits the transfer of a data maintenance request action among
parties involved in the preparation, processing, assessment,
resolution and directory production processes.
1.2 Field of Application
The Data maintenance request definition message may be used for
both national and international applications. It is based on
universal practice related to administration, commerce and
transport, and is not dependent on the type of business or
industry.
1.3 Principles
The message permits the transmission of a Data Maintenance
Request (DMR).
The message may be exchanged at the regional or national level
between the DMR submitter and the secretariat that acts as the
entry point for DMR submissions to the submitter's technical
assessment group. It may also be exchanged at an international
level among the secretariats for the assessment function as
well as those participating in the production of the
directories.
At the regional or national level the first DMRDEF sent for a
given DMR will be from the submitter to the entry point
secretariat utilizing the submitter's own reference number.
On an international level the first DMRDEF sent for a given DMR
will be from the entry point secretariat to the central
secretariat utilizing the entry point secretariat's own unique
reference (Log) number. All DMRDEF messages initiated after
registration at the entry point secretariat will use the entry
point secretariat Log numbers. All DMRDEF messages initiated
after registration at the international level will use the
central secretariat's Log number. The Data maintenance status
report/query(DMSTAT) message will be used to notify all
applicable parties of the latest log number assignments and
other necessary status information.
The DMRDEF message shall contain only a single Data maintenance
request.
For submissions of messages that allow the inclusion of
substructure maintenance requirements in the same DMR, the
segment identification segment group, the composite data
element identification segment group, the simple data element
segment group, and the code set identification segment group
are to be used to provide the modified substructure relative to
the message's boilerplate. A structure defined below the
message level, as part of a Message submission, must include a
change indicator in the associated attribute segment of the
structure to indicate that the structure is being detailed as a
proposed modification in association with the message.
The reference segment shall identify all related parent and
child DMRs one level above and one level below the current
level.
DMRs which change an existing entry must provide a complete
replacement entry with the changed parts identified via the
change indicators. All changes to message structure must also
include all resultant changes to boilerplate text.
Use of the default service characters is required and the
Interchange header shall specify character set level C.
Proper use of the DMRDEF message within supporting applications
assumes the availability and use of the EDI standard in
conjunction with originator data entry mechanisms in order to
ensure the accurate association of data maintenance actions
with the standard.

0050 FTX, Free text
A segment specifying text information outlining the business
requirement for this DMR. This segment may also be used by the
originating technical assessment group to convey any
explanations or comments which should accompany the DMR through
the international assessment process. Other assessment groups
will comment on a DMR via the DMSTAT message.
0060 RFF, Reference
A segment identifying the type of and reference log number of
this request, as well as any related DMRs.
In order to ensure proper identification of related DMRs, this
segment shall identify, if existing, any parent and child DMRs
one level above or below the current level. This segment shall
not identify grand-parents and grand-children at any level.
(Although a related DMR may have multiple parent DMRs and/or
multiple child DMRs, the parent and child DMRs for these
related DMRs will not be identified in the current DMR.)
A related DMR(s) at the highest level, will have no parent
DMR(s). A related DMR(s) at the lowest level will have no child
DMR(s).
The actual DMR reference log number type may be: Original
submitter, Entry point assessment log number, Central
secretariat log number, or International assessment log number.
The related reference log number type may be:
Original submitter, parent DMR
Original submitter, child DMR
Entry point assessment log number, parent DMR
Entry point assessment log number, child DMR
Central secretariat log number, parent DMR
Central secretariat log number, child DMR
International assessment log number, parent DMR
