S1000D History

In the early 1980s, the concept of S1000D specification originated in the aerospace field within Aerospace and Defence Industries Association of Europe (ASD). Earlier in Europe various national specifications were used in technical documentation, this made data exchange between countries more difficult. During this same period, civil aviation was successfully using ATA S100 specification to deliver and exchange information internationally. The Aerospace and Defence Industries Association of Europe (ASD) had developed the S1000D specification, originated from the Air Transport Association (ATA) S100. From then on it emerged as a widely adopted standard in Europe by military projects.

S1000D also known as ASD S1000D is an international specification for the procurement and production of technical publications based on XML (extensible Mark-up Language), utilizing a Common Source Database. This specification offers a structured procedure regarding organization, processes, and management in the process of technical documentation and their publishing’s. It has become widely utilized and highly regarded across various sectors, and a good choice for documenting complex equipment with long life cycles such as defence, civil aviation, space, shipping, nuclear, automotive, rail and manufacturing. Finely tuned structures in this specification can also support sophisticated military and civil project life cycles.

The S1000D specification is now supported by the successor to AECMA, the Aerospace and Defence Industries of Europe (ASD), the Aerospace Industries Association of America (AIA) and the Air Transport Association (ATA). The specification is controlled by an international body, the S1000D Steering Committee (SC), which is responsible for maintaining it and includes members from both government agencies and industry. To address the rapid development of information technology, the SC is supported by a group of specialists known as the Electronic Publications Working Group (EPWG).

ASD S1000d Specification-smartifysol

S1000D covers the planning, management, production, exchange, distribution and use of technical documentation that support the life cycle of any civil or military projects that include air, land and sea vehicles.

Business Rules

Business rules are major because they determine the implementation and processes to ensure consistent and complete content. These are decisions created by a project or an organization on how to implement S1000D. S1000D business rules are documented based on project and/or organizational requirements, and these determine and constrain all elements of a technical publication or the project.

S1000D also specifically defines Business Rules Decision Points (BRDPs). Business Rules Decision Points help us to create instructions and guidelines that affect authoring, presentation and distribution of publication for a project. Business rules written in computer language are stored in the BREX document. That BREX data module is then referenced inside each data module, hence the software and applications can validate that data module’s content to the referenced BREX.

S1000D now contains business rules categories. Combining your business rules into these business rules categories helps you with scope and normalization. The 11 business rules categories of S1000D are listed below:

The 11 Business rules of S1000D Specification

1. General Business Rules

General rules cover overall decisions made by a project or an organization that are not covered by any of specific business rule categories. They serve as overall decisions for the implementation of S1000D.

These include

  1. What issue of S1000D suites the project.
  2. Parts of S1000d to be used in project implementation.
  3. Defining the terms used throughout the project.

2. Product Definition Business Rules

Product definition business rules covers the data module coding strategy as to how the product is broken down either physical or functional. Including the model identification codes down subsystem level, supplier subsystems, applicability and identifications also need to be considered.

3. Maintenance Philosophy and Concepts of Operation Business Rules

These rules cover

  1. Usage of Item location codes.
  2. Decision on how to apply information code variants.
  3. Specifying information codes and information names that can be used in the project.
  4. Project specific information sets in detail.
  5. Deciding on how information code variant can be applied.
  6. Training and Skill levels.

4. Security Business Rules

Following are the business rules are included

  1. Defining of security classifications
  2. Copyright markings
  3. Use of disclosure
  4. Instructions for destruction
  5. National security restrictions
  6. Defining access to various “Classes” of data modules

5. Business Process Business Rules

Business process business rules cover the interaction with other disciplines into Technical Publications in an organisation, project level of organisation or project as a whole, agreed workflow procedures between manufacturer, subcontractor and customer and reuse of content across systems including training environment.

Rules to be considered in preparing a strategy for data module coding are

  1. The optimal reusable data granularity for screen presentation in learning products and the system maintenance philosophy for presentation in IETP.
  2. The development of maintenance, operational and learning content for use in interactive multimedia and simulations.
  3. The process of developing the appropriate amount of data modules that meet the intended need of an SCO in SCORM.
  4. The relationship between data module/publication module codes and the requirements for learning content registration.

6. Data Creation Business Rules

Data creation business rules give information about the creation of text, illustrations and multimedia objects.

The data creation business rules include:

  1. rules for creating textual data
  2. rules for creating graphics, 3D content and multimedia objects

6(a). Data Creation Business Rules - Text

Text creation business rules consist of rules and guidelines (including terminology rules such as language and dictionaries, and the order of preference) for maximizing the amount of reuse that can be achieved within technical publications, and between technical publications and supporting training content.

Text creation business rules provide rules and guidance how the technical and learning content is to be developed. They also specify eg the use of dictionaries, how numbers must be expressed, how the author must refer to technical terms, how multimedia, maintenance, operational and learning content is to support IETP and training, and the establishment and use of a terminology database. Markup business rules provide information about which markup elements and attributes must be used and populated. These rules are often project or organization specific.

6(b). Data Creation Business Rules - Illustrations and Multimedia

Illustration and multimedia creation business rules cover the creation of illustrations and multimedia objects. They are divided into style, detail and data format. Data style rules for illustrations and multimedia objects govern characteristics such as illustration sizes, use of color, line weights, fonts, projection methods (isometric or trimetric), etc.

The rules for illustrations cover for example the use of hotspots.

Data format rules cover the formats in which the information must be stored. For a CGM illustration, this will cover the elements that are permitted (eg coordinate types, polylines, restricted text). For raster images it can include the resolution and orientation. It is often difficult to separate style from format.

7. Data Exchange Business Rules

This data exchange business rules includes rules for usage of Data Dispatch Note (DDN), Data Module Requirements List (DMRL), Data Module List (DML), CSDB status lists, File based transfer protocol, Data exchange frequency. Rules for data module issue numbers and agreed criteria for acceptance and rejection between partners and customers. Acceptance and rejection are based on agreed criteria.

8. Data Integrity and Management Business Rules

These business rules enforce the referential integrity within the CSDB and are closely joined with the data exchange business rules and cover how creators and customers manage data. This includes internal, external workflow and Quality Assurance rules and processes. If required, this business rule category can contain rules determining the procedure for submission and acceptance of non-compliant information when providers are unable to generate S1000D compliant data.

9. Legacy Data Conversion, Management and Handling Business Rules

Legacy data conversion, management and handling business rules are totally different from other business rule categories which are mentioned above. This includes conversion rules containing mappings between elements and attributes of source and target specifications and rules for inclusion of legacy information in technical publications Eg: ATA ISpec 2200 project.

10. Data Output Business Rules

These data output business rules contain information over how to style elements and attribute content. The data creation business rules are associated with this data output business rule category, these rules define output formats for S1000D data and contain Interactive Electronic Technical Publication (IETP) formats, Sharable Content Object Reference Model (SCORM) formats and multimedia formats.

S1000D Data Modules

The content developed using S1000D standard stores data in the form of data modules in a Common Source Data Base (CSDB). Each data module is assigned a unique Data Module Code (DMC) that serves as a unique identifier, and implies to what type of element and data it holds. This prevents duplication of content into the CSDB. Data module codes are used to manage data modules in the CSDB. S1000D data modules are structured in accordance with their content type. At present there are 21 data module types, with content that vary from descriptive and procedural content, over to the added functionality carried by the applicability and technical repository data modules. S1000D offers SGML Document Type Definition (DTD) and XML Schemas to support these data module types. It should be noted that beginning with Issue 4.0 of the S1000D specification, only XML Schemas are defined.

Each data module is divided into two main parts, they are:

  • An identification and status section (which is common to all data module types)
  • A content section (particular to each data module type)

A list of current S1000D data module types are:

  • Applicability cross-reference information
  • Business rules exchange information
  • Conditional cross-reference information
  • Container information
  • Crew/operator information
  • Descriptive information
  • Fault information
  • Illustrated parts data
  • Maintenance checklists and inspections
  • Maintenance planning information
  • Procedural information
  • Process information
  • Products cross-reference
  • Reference information
  • Common information repository
  • Training information
  • Wiring data information
  • Wiring data description information
  • Checklist
  • Learning
  • SCORM Content Package

As the name indicates, the ID and Status Section consists of all the data needed to find the data module in terms of its identification, or data module address. It also contains data related to its status, like its verification status, source information, security classification, applicability and other necessary information. The content section includes all content intended for the user information and is specific to the data module type. Identity of each data module is achieved using a coding system that offers unique identification code for each data module and prevents duplication. This code is also used for file identification, as it is used to form the data module's filename. S1000D is very particular on the rules for this coding system known as the Data Module Code or DMC.

Common Source Database

The key element in information management is the CSDB. It is an information store and management tool for all objects required to produce the technical publications within projects. S1000D does not specify the design and implementation rules for a CSDB. It only specifies the data structure of the information objects, which is independent from any software implementation. All data modules applicable to the Product are gathered and managed in a database, which is here after referred to as the CSDB. A benefit of the CSDB is to enable production of platform-independent output in either page oriented or IETP. Data managed in S1000D is not duplicated in the CSDB. Data modules enable data to be stored once and used for multiple outputs. A single change to an individual data module can update multiple outputs and multiple deliveries.

DATA MODULE CODES

Data module code is partitioned into three types:

  1. Hardware identification
    • Model identification code, System difference code, Standard Numbering System, Unit or assembly, Disassembly code, Disassembly code variant comes under hardware identification partition.
  2. Information type
    • Information code, Information code variant, Item location code comes under information type partition.
  3. Learn type
    • learn code, learn event code comes under learn type partition.

Information Control Number

Illustrations and multimedia are determined by a unique information control number. In a CSDB, ICN is the unique identifier of an illustration sheet, multimedia object, or attached data, and is used to establish the relationship to one or more data modules. The ICN is independent of file format and includes in the following mark-up elements:

Illustrations are usually

  • Vector line drawings (CGM)
  • Raster images (CCITT Grp/4, TIFF)
  • Photos and another Artwork (JPEG, GIF, PNG)
  • Multimedia can be of any defined type and are supported by the project’s business rules.
How to create a Information Control Number in S1000D Specification

In the process of Information Control Number here are the 6 steps to be followed, whereas Model Identification Code, System Difference Code, Standard Numbering System and Assembly Codes are similar and covered in the Data Module code breakup above. Once these steps are completed we will get a complete code like below. Example Information Control Number: - ICN-S1000DBIKE-AAA-DA10000-0-U8025-00512-A-004-1.

ICN-Information Control Number S1000D Specification 1. Creation of Responsible Partner Company Code

The Responsible Partner Company Code must contain 1 character , it is the company or organization responsible for the illustration multimedia object or other data independent of its use in the data module. It should be determine by the project or organization. Eg: 0 is chosen as Responsible Partner Company Code.
