SDL Trados

History

Trados GmbH was founded as a language service provider (LSP) in 1984 by Jochen Hummel and Iko Knyphausen in Stuttgart, Germany. The company began developing translation software in the late 1980s, and released the first Windows versions of two of the suite's major components in the early 1990s – MultiTerm in 1992, and Translator's Workbench in 1994. In 1997, the company received a major boost when Microsoft decided to use Trados for its internal localization needs.

Trados was acquired by SDL in 2005.

Configuration

SDL Trados Studio is delivered with several tools and applications. These are:

SDL Trados Studio

The main application providing a complete environment to edit or review translations, manage translation projects, organize terminology, and connect to machine translation.

SDL MultiTerm

A terminology management tool that is integrated with SDL Trados Studio for adding, editing and managing terms.

SDL Language Cloud

Secure access to machine translation engines that can be accessed directly from within SDL Trados Studio.

SDL AppStore

SDL Trados Studio includes several applications on the SDL AppStore - an online marketplace which offers apps to help with a range of translation processes, for example further file format support and task automation.

Supported source document formats

SDL Trados Studio supports over 70 different file types, including: various markup and tagged formats such as SGML, XML, HTML, XLIFF, SDLXLIFF (Studio's native format for translation), OpenDocument files; straight text files; source code files, such as Java and Microsoft .NET; Microsoft Word, Excel, Bilingual Excel and PowerPoint; and some Adobe file formats, such as PDF, scanned PDF (OCR is included) FrameMaker, InDesign, and InCopy.

Handling of translation memories and glossaries

The translation memory (TM) format of Trados is SDLTM, which consists in a particular SQLite database.

When creating a new (file-based) translation memory, SDL Trados Studio creates a database file in which all translation units are stored. The translation memory also stores structural and context information to link all the different segments and their position in a document. This allows the tool to select the most relevant translation memory segment.

Main translation memory database file: .sdltm

In previous version of Trados a neural network of files that enable fuzzy search capability was also created. A new translation memory consists of five new files:

Main translation memory database file: .tmw

Neural network files: .mdf, *.mtf, *.mwf, *.iix

When copying a translation memory, you must copy all five translation memory files. Otherwise, Translator's Workbench displays an error message when opening the copied translation memory.

Trados can also work with server-based translation memories.

Glossaries are handled by the MultiTerm application. Glossaries can be bilingual or multi-lingual.

Integration of Machine Translation and Post-Editing

SDL Trados Studio has integrated machine translation and postediting into its translation workflow. If the appropriate parameter setting is made, SDL Trados Studio will insert a machine translation of a translation unit (TU) if no match is found in the translation memory. The translator can then post-edit the machine translation for added clarity. SDL Trados currently supports the following MT systems: Language Weaver, SDL BeGlobal, SDL LanguageCloud and Google Translate. SDL Trados Studio also supports the integration of Microsoft Translator and other MT system through its open API and plugin architecture on the SDL OpenExchange.

SDL AppStore

In December 2010 SDL launched the SDL OpenExchange, now known as SDL AppStore, a web portal allowing independent developers to leverage the software's open architecture to create applications and plug-ins for SDL Trados Studio. Apps can be downloaded to add functionality missing from the base product, such as legacy file support and new machine translation plugins. As of 15 December 2011 over 25,000 apps have been downloaded.

Market share

According to a 2004 survey by the World Bank, Trados held an estimated 75% global market share with SDL holding an additional 10%.

According to the ICU Translation Memory Survey from 2006, SDL Trados is used by a total of 75% of surveyed users - 51% used Trados with a further 24% SDL Trados (See table 21).

Documentation and help

SDL Trados manuals can be downloaded online from the company's website. Basic training is available in the form of webinars delivered free of charge on a monthly basis, while there is also onsite training at SDL and partner (Authorized Training Center) locations. A calendar can be found on www.translationzone.com in the Event section. Educational videos can be found on www.youtube.com/sdltrados.

Criticism

SDL Trados has been criticized for various issues such as lack of backward compatibility.

A number of solutions have been created for handling the different versions of Trados file formats, but the process is not failproof. SDL did apparently respond to user complaints of licensing complexity and problems by simplifying the licensing scheme used in the SDL Trados Studio 2011 Freelance release.
