(This section contains information of a general or explanatory nature that may be helpful, but is not mandatory.)
6.1 Intended use. An IETMDB is the source data for the preparation of IETMs. IETMs prepared in
accordance with this speciication are intended for use in the installation, operation, maintenance, repair, and
logistics support of equipment/systems or for the accomplishment of the assigned mission of users.
6.1.1 Nature and purpose of a revisable source database. For complex weapon systems and other types of
military equipment, adequate logistic support in all its forms requires an enormous amount of current, readily
accessible, accurate, and highly detailed data, consisting of TI. This information has been traditionally
prepared and distributed to the end user in paper form; but with new technology, it can be better and more
effectively displayed or presented electronically and interactively to an end user. The material presented is
derived from material stored in textual, graphical, audio, or video form in a revisable database which is
composed of logically connected but randomly accessible IETM data elements. It is this starting point of the
IETM electronic data chain that is speciied in this document. An integral part of the IETM concept and, in
the larger arena of the DoD Computer-aided Acquisition and Logistic Support (CALS) program, is that the
services can acquire and maintain large scale databases. They can also gain access to such databases
that are maintained continuously by a contractor.
6.1.2 IETMDB capabilities. An IETMDB is a complete collection of database elements relating to a
weapon system or other equipment acquired by the Government and constructed in a standardized manner
to provide the following capabilities:
a. The IETMDB can serve as the basis for construction and update of the entire suite of
electronically displayed, weapon system, IETMs through the use of automated authoring systems.
b. Government activities or DoD contractors concerned with logistic support for the weapon
system involved, can access the database directly to obtain needed logistic support information
for speciic purposes.
c. The IETMDB, or portions of it, can be interchanged by means of standardized formats and
procedures throughout the DoD and its supporting contractors when needed for any purpose.
6.1.2.1 References for composing graphics. Information about composing graphics may be found in
MIL-HDBK-28001, MIL-STD-1840 and ISO 8632-1.
6.1.2.2 Development of content speciic DTDs. Refer to MIL-PRF-28001 Markup Requirements and Generic
Style Speciication for Exchange of Text and its Presentation, for guidance to develop content speciic DTDs.
6.2 Acquisition requirements. Information for acquisition documents may include:
a. Title, number, and date of the speciication.
b. If IETM program requires content speciic layer elements other than the content speciic
layer elements provided by TMSS (see 3.2.).
c. If the speciication applies to the delivery and tagging of an IETMDB (see 3.2a.).
d. If the speciication applies to the structuring of the IETMDB and naming of the IETMDB
elements which are created and maintained by the contractor (see 3.2b.).
e. Content speciic DTDs other than the one provided by TMSS and whether these are to be used
in addition to or instead of the one provided by TMSS. (see 3.3.4).
f. If Validity is to be the responsibility of the Contractor (see 4.1).
g. Packaging requirements (see 5.1).
6.3 Technical information procurement options. Acquisition of IETMs may be carried out by one of several
optional approaches. This speciication provides requirements for a standardized IETMDB which will permit
the Government to acquire TI by applying any of the following contractual options:
a. Acquisition of only the required inal form IETMs. Although the author (equipment prime
contractor) will need to establish an automated equipment or weapon-system (source) database,
this database will not be acquired by the Government. The contractor will maintain, use, and
