Supported Terminology Exchange Formats

XML Formats

Acrolinx natively supports the ACTIF and OLIF formats, but you can also import or export terms in custom XML-based formats with transformation style sheets. The main advantage of XML-based formats is that there are fewer mapping steps required when importing terms in the term import wizard.

ACTIF and Custom XML-based Formats

ACTIF (Acrolinx Comprehensive Term Interchange Format) is the native terminology exchange format for the Acrolinx Terminology Manager. ACTIF has a similar structure to most standard terminology exchange formats such as TBX (Term Base eXchange). You can use the ACTIF format to exchange terminology between different installations of Acrolinx.

You can also import or export almost any other XML-based terminology file by using transformations to convert the file into the ACTIF format. You Acrolinx project consultant can help you create a style sheet that transforms your preferred XML format into ACTIF.


OLIF (Open Lexicon Interchange Format) is an open standard for lexical and terminological data encoding and is implemented as an XML Schema and an XML DTD. To learn more about the OLIF schema, visit the OLIF website.

About Transformations

A transformation is a style sheet that does the following:

  • Converts an XML-based terminology file into the ACTIF or OLIF format during the import process.
  • Converts an ACTIF or OLIF file into another XML-based terminology file during the export process.

Transformations are configured based on your data model and individual file transfer requirements and delivered with your guidance package. If your data model changes (for example by adding or renaming custom fields), the transformation files must be adapted to reflect these changes and to ensure a correct export of the data model.

If you’re not sure which transformation to use, or there are no transformations available for your file format, contact your Acrolinx administrator.

Adding a New Transformation Style Sheet or Style Sheet Location

You can use transformation style sheets to import or export XML files that aren’t in the either of supported ACTIF or OLIF formats. If you’ve created a new transformation style sheet or have received a new transformation style sheet from your Acrolinx project consultant, you can update your installation by copying the new style sheet to your Acrolinx installation directory.

By default, the transformation style sheets are in the data directory: <INSTALL_DIR>\data\transformation

You can also specify an alternative location by using the core server property terminologyManager.transfer.transformationPath

The default value is:


This path is relative to the directory <INSTALL_DIR>\server\bin

To add a new transformation style sheet, follow this step:

Copy the transformation style sheet to the directory where transformation style sheets are stored.

Unless you have configured an alternative storage location, copy the style sheet to the following directory:
