NAVAIRINST 4120.11
b. TMs, ETM, and IETM XML formatted deliveries to NAVAIR
shall include an XML source file and entity files.
(1) An XML source file consists of TM text with installed
XML tags. The XML source file will be stored and kept in a
TMAPS repository or a database in NATEC.
(2) Entity files are connected with an XML source file and
may be created and referenced by the DTD. Usually, entity files
are designed when there is standard text in a document that will
be used or shared among instances of a class of documents.
Contents of entity files are available to any document using a
connecting DTD. Instances are actually marked-up textual data.
(3) FOSIs are used in conjunction with the applicable DTD
to provide for the formatting and printing of paper TMs in work
package format.
(4) Style sheets are used in conjunction with the
applicable DTD to provide for the look and feel and certain
navigation capability for the computer display of IETMs.
(5) A description of how XML tags are used can be found in
the DTD Data Dictionary.
(6) The Tagging Conventions document is used as an aid in
tagging and developing a XML source file for a NAVAIR TM.
c. An ETM is a TM normally prepared from a linear Standard
Generalized Markup Language (SGML) or an XML document file. The
ETM is also displayed on an Electronic Display System (EDS) in a
sequential or document oriented manner. The data author largely
predefines the sequence of data presentation. It is an
organization of technical data that replicates the order of
information found in a page-based document. There is generally
a default “path” through the technical data. The ETM may employ
a combination of an automated intelligent index and linked
reference data.
d. An IETM is a technical manual prepared in digital form and
designed for interactive display by means of a computer
controlled EDS. The information is not displayed in a
sequential fashion. The organization of content does not follow
a document or page-based paradigm. There are high levels of
interactivity between the data and the user. The order of
presentation is dictated by inputs from the user, external
sources, or events (as in diagnostics). There may be multiple
paths through the data. Individual paths through the data are
