Issue 7 of the specification fully replaces all previous issues and revisions. A data module is a self-contained unit of information, such as a couple of paragraphs, a figure, or a table. An actual XML hierarchy must be designed specifically for each different knowledge domain.


To request your copy, please follow the instructions on the Downloads page. Data modules have two sections: Today, the success of STE is such that other industries use it beyond its original intended purpose of aerospace maintenance documentation. There are no additional charges or royalties required.

The standard originated with the European Association of Aerospace Industries AECMAwhich represents the aerospace industry in the fifteen European Union nations in matters of common interest-technical, financial, legal, and economic. In adcma, it defines a Common Source Data Base CSDB 1000d provide source information for compilation of the publications and for use in electronic logistics information systems to deliver modules of information direct to the user.

English is the international language of science, technology 1000 human relations. When change is required only the single DM needs to be changed whilst the changed information appears throughout the output, an example of the fundamental CALS philosophy eacma ‘create once, use many times’ Views Read Edit View history. It provides for creation of documentation using the principles of modularity and minimalism, supporting the “ability to readily identify relevant information at the lowest level possible.

Each module has its own identifier-the data module code DMC -that aids in ensuring that every piece of information placed in the CSDB is unique. Items of information, which are repeated in different contexts, for example, warnings, opening and closing procedures, can be stored once as a single data module and aecka be used many times in different contexts. From Wikipedia, the free encyclopedia. Knowledge so partitioned and classified can therefore be shared among many publications, and updating of items in the underlying SD XML document will automatically affect updating of the dependent publications.


SD can be downloaded for free at its official project website. It is this feature together with the modular approach to data creation and storage that aeecma the specification so 11000d to the wider international community In aviation, it is mandatory to correctly understand maintenance and operation documentation to make sure that systems operate safely and correctly and to protect human lives.

The modular concept assists in the generation and simplification of electronic commenting procedures by its ability to readily identify relevant information at the lowest level possible. A small to medium project will often consist of 10, or more data modules.

SGML and XML are system and platform independent data formats, thus enabling interchange of technical information across software applications. It is an XML specification for preparing, managing, aaecma using equipment maintenance and operations information. There is an interface specification with SL Issue 1. However, it is not often the native language of the readers of technical documentation.

SD is an international specification for the procurement and production of technical publications. Interest in STE has also increased dramatically in the areas of language services, professional translation and interpreting, as well as in the academic world. For example, it identifies the version of the data module as well as the security settings which determine who can make changes to the module The combination of data module code, information types and DM metadata allows a selection of subsets of information to be chosen by query or table of contents designed to eacma a specific users needs.

SD requires a document to aevma broken down into individual data items called Data Modules which can be marked with individual XML labels and metadata, and be part of a hierarchical XML structure. That has resulted in new documentation being written for every new product, even if the product is likely comprised of many of the same physical components and sub-components used in other products.


The writing rules rule wording, explanatory texts, and examples and the dictionary have been fully revised. The DTD and Schemas have a modular form. STE was developed to help the readers of English-language documentation understand what they read, particularly when these readers are non-native English speakers. Information is stored in the CSDB in small chunks, called data modules. The 1000f also identifies how the subcomponents being documented relate to larger components that comprise a piece of equipment.

The specification is free to download and use, although it is recommended that advice be sought on the best methods for implementing an SD repository. It is also the language of the aerospace and defense industry. These two groups explored the existing controlled languages and researched texts in several maintenance manuals.

AECMA SD “incorporates a methodology for storing data in electronic form and provides the capability to output information both in electronic and, if required, paper format. This permits the updating of single data items without necessarily changing the path down the XML tree which points to them.

Retrieved from ” https: That standard is Specification D SD. This page was last edited on 3 Augustat This modular design of DTD and Schemas allows for incremental update when new types of data modules are required.

This provides considerable savings in data maintenance and enhances data configuration control. Many readers have a limited knowledge of English. The specification has since been modified for use with land, sea, and commercial equipment. The purpose of storing discrete chunks of information in the database is to promote reuse of the information in as many different technical documents as possible.

Complex sentence structure and the large number of meanings and synonyms that many English words have can cause confusion. List of document markup languages.
