4.1.3.2 . Purpose and goal. This document provides a resource of
tools, which helps the acquisition manager contract the
functionality required in IETMs. The acquisition process should
be in a manner that can subsequently be priced by bidders and
compared and contrasted in a competitive bid. This document is
intended to provide guidance of the relative complexities of
these functionalities, which equates to costs, as well as a
draft statement of objective language that can be tailored for
the acquisition of an IETM.
4.2 . Determining IETM functionality. Consideration should be
given to the features and capabilities that are desired to
support users from novices to advance. Refer to the IETM
Functionality Matrix for additional information.
5. VIEWER COMPONENTS.
5.1 . Overview. The Web viewer is an integral component that
resides on the client side. It should support the features
needed by the server side that provides the functionality to the
IETM. Because IETMs provide a range of capabilities to the
user, the browser should be capable of supporting a range of
features as well.
5.2 . Available viewers. Currently, there are two major viewers
featuring competing technologies that may support IETM
capabilities. Microsoft's Internet Explorer and Netscape's
Navigator both support basic Web surfing capabilities. However,
when higher level scripting is introduced, there is the chance
that incompatibilities may be encountered. It is important to
design the IETM to detect the type of viewer in use by the
client and provide the appropriate code to support that
particular viewer across all platforms.
5.3 . Outer shell. The outer shell (see figure 1) is the portion
of the screen that surrounds the inner shell. IETM developers
should not attempt to modify or control the outer shell.
5.4 . Inner shell. The inner shell (see figure 1) is the portion
of the IETM, within the browser shell, provided as the client
application display area. The only portion of the screen real
estate under the developer’s control is the inner shell. The
outer shell is the portion of the screen that surrounds the
inner shell. The developer should not attempt to modify or
control the outer shell. As technology changes, the impact on
the outer shell is unknown. For example, the Task Force Web
Portal and the User Facing Service do not allow the developer
the flexibility to control the outer shell. The inner shell
contains specific regions, these regions are:
