Fluenta DITA Translation Manager

Fluenta logo

Fluenta is an open source tool designed to simplify the translation and localization of DITA projects by combining two open standards from OASIS: DITA and XLIFF.

Fluenta implements the workflow described in the article Use XLIFF to Translate DITA Projects, making it easy to manage the translation side of your DITA projects according to the procedure recommended by the OASIS DITA Adoption Technical Committee (see the official TC publication, available in PDF format from OASIS and in HTML format from

DITA is an XML vocabulary, but not just any XML. It has certain peculiarities that are not easily handled by a standar XML editor or a translation tool.

Just like an XML editor that is good for authoring in DITA, a translation tool that can properly handle DITA files should:

  • Be able to resolve DITA content references, such as the conref attribute or the keyref mechanism;
  • Support DITA specializations that allow customization of translatable elements and attributes.
  • Understand the translate attribute.

Fluenta is designed to handle all of the above issues.

A DITA project can contain hundreds of small files. That's not unusual but it usually makes file handling a bit tedious. Fluenta is able to parse a DITA map, resolve the references to all topics and subtopics, and prepare a unified package that you can send to your Language Service Provider (LSP).

If your LSP charges you for file management, you can reduce costs by preparing a consolidated translation package in-house using Fluenta.

How it works

  1. Start by creating a new project in Fluenta. All you have to do is specify the location of your DITA map, a name for the project and select the languages that you want to translate into.
  2. When you are ready to translate your project, ask Fluenta to generate an XLIFF file.
  3. Send the XLIFF file to your Language Service Provider and wait for a translated XLIFF or translate yourself using a CAT tool such as Swordfish Translation Editor.
  4. Import the translated XLIFF and choose a folder where to store the translated version of your map and topics.

After updating your DITA content, you may want to update your project's translations. All you need to do now is:

  1. Ask Fluenta to create a new XLIFF file.
  2. Send the XLIFF file to your LSP and wait for a translated XLIFF.
  3. Import the translated XLIFF and select the folder where you want to save the updated translated version of your map and topics.

Fluenta automatically recovers In-Context Exact (ICE) matches from the translation saved in the previous cycle. This means you don't have to pay again to translate content that hasn't changed.

Thanks to the Translation Memory technology included in Fluenta, you can also recover translations of parts that have changed slightly.
