Interactive Electronic Technical Manuals
In an overview IETM (Interactive Electronic Technical Manuals) come up with the problems with the general characteristics along with an identification in the three services leading up to IETMs. It defines the new style of presentation medium with general areas including initial standards for “new start” programs. For each and every emerging Electronic Technical Manual classes “IETM” stands for a call.
IETM is the replacement of paperwork which is equivalent to a paper-based presentation. IETM becomes as the advantage for the medium for displaying an electronic display screen along with the redesigned with its associated computerized control system. IETM is designed in a user interactive mode which can be displayed text along with the specific graphics while displaying and this can be used as a guide to the users in a procedure manner.
Here levels are defined by the Tri-Service IETM Working Group which are classified as Level 0, Level 1, Level 2, Level 3, Level 4 and Level 5. Level 0 gives us the full description of the spectrum and Level 5 gives the future innovations which are not available till now. So that’s why Level 5 is known as open-ended Level. Now let us see in detail about the Levels.
Level 0: Non-Electronically-Indexed Page Images
As we all know that Level 0 gives us the full description of the spectrum by providing the digital page with images that can be mean to plan for electronic archival filing. These pages allow the users to view only on an electronic device but it does not have the detailed index for navigation with this document for the online purpose.
Level 1: Electronically Indexed Page Images
In this level systems with a digital page with images are provided with full page display and it allows the navigation by means of user-friendly which can be an automated index page. For e.g: Navy Advanced Technical Information System – ATIS). This type of systems which can be used in libraries and as well as used for reference setting for research and reading purpose.
Level 2: Electronic Scrolling Documents
Systems for Interactive Display of ASCII-Encoded Documents using an intelligent index and Hypertext tags inserted into an attached document file. In general, the document is the result of a simple conversion from a page-oriented document but with little or no alternative by a subject matter expert with the exception of adding hypertext tags. These allow a user to navigate through the document, but have very limited, if any, author inserted navigation aids or a content-driven "NEXT" function.
Level 3: Linear Structured IETMs
Interactive Display of Technical Information which is SGML tagged using MIL-D-87269 tags to the maximum extent possible and using a Hypertext presentation system for display in accordance with MIL-M-87268. It is based on a sequential SGML document file and not a hierarchically based on Database. Navigation is based on author developed make employing features such as to bring dialog boxes and content-driven logical "NEXT" function.
Level 4: Hierarchically Structured IETMs
Interactive Electronic Display of Technical Information specifically authored into and maintained as not characterized relational or object-oriented hierarchical database. These source data are subsequently packaged (i.e., "view-packaged") as a run-time database for Interactive Presentation in accordance with the DoD IETM in detail (MIL-M-87268, MIL-D-87269, and MIL-Q-87270). This level differs from level 3 largely in the manner in which the source data is managed. The user presentation may be very similar.
Level 5: Integrated Data-Base IETIS
As we all know that Level 5 is an open-ended level which is known as Integrated Electronic Technical Information System (IETIS) for Interactive Presentation of level 4 IETMs integrated with the data for other processes, including Expert-System rules for the display of information and other user-applications such as characteristic or computer-managed training. This level is meant to include future applications and features not yet developed or sufficiently mature for production use.
