4. GENERAL GUIDANCE.
4.1 . General. The objective of IETM acquisition is to procure
standard SGML/XML/XSL tagged IETM data that is optimally
structured with internal reference linking to create survivable
data in revisable and economically maintained databases by
sharing common objects. Although, interactive PDF with internal
reference linking is allowed the goal is to acquire XML tagged
documents.
4.1.1 . Integrated Data Environment (IDE). The IDE is a dynamic
data environment in which all users draw from a common virtual
database containing data maintained by an unlimited number of
Government or commercial service providers. This philosophy is
a key element in the migration toward the IDE. A shared
information environment providing immediate access to digital
data supports the IDE.
4.1.2 . IETM acquisition choices. An IETM may also be procured as
a logistic support product under a major weapon system or
equipment buy, as a separate item under its own contract to
support new equipment, or as a conversion.
4.1.3 . IETM acquisition considerations. There are a number of
choices to be considered for the acquisition of IETMs, several
of which may have a direct impact on the type of technical data
presentation method that is contracted for.
4.1.3.1 . Resources. Resources also are provided that may help the
acquisition manger evaluate the cost benefit associated with
IETM acquisition and trade off higher functionality requirements
with maximum return on investments.
