The European Aerospace Defence Industries (ASD) devised the S1000D specification concept in the early 1980’s. A variety of national specifications were used before that time, making it more difficult to exchange data between countries. At the same time, the aviation industry was succesfully using the ATA S1000 specification to deliver and exchange information internationally. In fact, the S1000 specification of the Air Transport Association (ATA) was the cornerstone used by the European Aerospace Defence Industries (ASD) to develop the S1000D specification.

The S1000D is based on XML (Extensible Markup Language) and sets forth a structured approach for the organisation, processes and management involved in generating and publishing technical documents. This standard has been well-received in numerous sectors, including the aviation, space, maritime trasnsportation, automotive, railway and manufacturing industries and is specially suited for the documentation of complex equipment with extended life cycles. 

The S1000D specification is currently endorsed by the European Aerospace Defence Industries (ASD), the United States Aerospace Industries Association (AIA) and the Air Transport Association (ATA) and is under the supervision of the S1000D Steering Committee (SC), sponsored by the Electronic Publications Working Group (EPWG) to address technological breakthroughs. 

Business Rules in the S1000D: Fundamentals for Content Coherence and Completion

Business rules are essential in the S1000D, insofar as they guide the implementation and processes that guarantee that content is coherent and complete. These rules are classified into 11 areas, ranging from general operation rules to specific rules for the conversion and management of inherited data. 

The content developed by the S1000D specification stores the data in data modules within a Common Source Data Base (CSDB). Each data module is assigned a single Data Module Code (DMC) that serves as a unique identifier and indicates the type of element and data contained in it. 

Data module structure:

Each data module consists of two parts:

  • Identification and status section:

The identification and status section provides information that enables:

  • Management of the data module in the CSDB
  • Management of data module applicability 
  • Management  of the quality assurance process
  • Control of recovery processes
  • Contents section:

The contents section provides users with the real information needed to perform the task or describe the system. The S1000D contains definitions of several types of information, such as:

  • Crew
  • Description
  • Procedure
  • Brakedown
  • Illustrated parts data
  • Wiring
  • Processes module
  • Business rules exchange

S1000D benefits: Optimisation of Technical Documentation Management


The S1000D specification stands out as a robust standard subject to on-going development that adapts to the ever-changing demands for technical documentation; an essential tool in projects that involve air, land and sea-based vehicles. Continuous updates and the support of international agencies warrant its revelance in the constantly evolving realm of information technology.

At Geminys, we make every effort to spearhead the effective implementation of the S1000D standard, thereby contributing to the progress and efficiency of the aerospace industry. Our dedication to excellence and conformity with the S1000D makes us a reliable partner in the face of the dynamic challenges and ongoing evolution of this sector.
