IETMs : An Interoperability Problem

MID	MID : An Implemented Solution

IETMs : What makes Them Unique ?

Descriptive Content

Procedural Content and Structure

Embedded document behavior driven by user interaction

Pre-conditions and post-conditions for each frame of information

Multiple document views: Navigation and display driven by user environment, e.g. which aircraft, what model/serial number, etc.

Consistent, Reliable Information Presentation

Today's Situation

Variety of COTS products used for delivery of IETMs

Delivery formats are not interoperable between viewers

Delivery formats and viewers tightly linked

Documents are authored/created for a specific platform and application

How Did We Get Here?

Data  MIL-PRF-87269

MIL-PRF-87269 - IETM Standard Data Structure

Content, Structure, and Behavior

No presentation semantics

MIL-PRF-87268

MIL-PRF-87268 - Standard for Presentation

Standardized user interaction

Layout, style

Standards - But no success

Not Just Another Standard

MID	MID History

U.S. Navy

MID Research Project Objectives

Scripting language to handle the logic in IETMs (behavior)

Provide compatibility with current standards and specs without modification

Provide consistency across dissimilar authoring and presentation systems

Can be implemented by existing IETM programs with minimum impact

MID Technical Overview

Defines standard set of "renderable" object types, combined with an internal scripting language that controls interaction

Does not require duplication of IETM DB content  HyTime    HyTime (ISO 10744) application   Specifically adapted to handle hypermedia (linked) information

"Standard" promoted by common API or interface

HyMID Browser Design

Current Status

Document Type Definition

Document Type Definition

32-bit Windows Reader/Browser Implementation

Conceptual design for a automated data authoring

Test IETM Implementation and Test Suite

Published API interface

Test Implementation software is free
