Class 4 – Hierarchically Structured IETM

An advanced IETM with hierarchical technical information, database-oriented content, interactive navigation, and structured access to technical information.

Class 5 – Integrated Database

An integrated technical information environment designed to connect IETM information with other application and support data.

IETM Class for Defence Services

JSG 0852 specifies Linearly Structured IETM Class 3 for use in Defence Services, while the guide also describes higher classes and their capabilities. Important capabilities include:

  • Keyword search
  • Online indices
  • Interactive navigation
  • Text & graphics integration
  • SGML/XML-based structures
  • Hotspot-based navigation
  • Security & access control
  • Annotation capabilities

The applicable IETM class for a specific defence project should always be determined according to the project requirements and applicable specification.

IETM Database – IETMDB

JSG 0852 provides guidelines for the Interactive Electronic Technical Manual Database (IETMDB). An IETMDB provides a structured collection of database elements relating to a weapon system or other equipment. It can support:

  • Automated IETM authoring
  • Updating technical information
  • Electronic technical information display
  • Logistic support information
  • Multiple access routes to technical data
  • Data relationships
  • Integration with other support applications

The guide also discusses the Content Data Model (CDM) for representing technical information and relationships between information elements.

Quality Assurance for IETM

Quality assurance is an important part of IETM development. JSG 0852 provides guidelines for establishing an IETM Quality Assurance Programme covering areas such as:

  • Source data management
  • Draft material evaluation
  • Database integrity
  • Authoring system capability
  • Validation
  • Verification support
  • Quality records
  • Final procedure preparation

A Quality Assurance Program Plan can define the scope, applicability, deliverables, validation activities, and other QA requirements for an IETM project.

IETM Security and Access Control

Defence technical documentation may contain controlled or sensitive information. JSG 0852 addresses access control requirements, including restricting IETM access to authorised users and providing additional controls for selected content and annotation capabilities.

Depending on the project, an IETM implementation can incorporate:

  • User authentication
  • Password protection
  • Role-based access
  • Content access restrictions
  • User activity tracking
  • Controlled annotations

IETM Content Requirements

A JSG 0852-oriented IETM can contain extensive technical information required for operation and maintenance. Typical information includes:

  • Equipment descriptions
  • Operating procedures
  • Maintenance procedures
  • Troubleshooting info
  • Technical drawings
  • Component info
  • Spare parts info
  • Safety instructions
  • Tools & test equipment
  • Technical specifications
  • Glossary
  • Acronyms & abbreviations
  • Warnings, cautions & notes

The guide specifically calls for accessible glossary information and appropriate warnings, cautions, and notes within technical information.

JSG 0852 and Technical Drawings

Technical graphics are an important part of an IETM. Technical information can be connected through interactive navigation and hotspots, allowing users to move between textual procedures, illustrations, drawings, and related information. This approach can make complex equipment documentation easier to understand and navigate.

JSG 0852 and 3D IETM

The 2025 revision also discusses developments in 3D technical manuals and interactive technical information. 3D technologies can provide an additional method for understanding complex technical content through:
